10 Reasons Why Your Car Won’t Start

It’s one of the worst things that can happen to a driver. You turn the key in your car’s ignition, perhaps hear a few alarming noises, and then…nothing. Whether in the parking lot after dinner, in your driveway before work, or even at the rest stop after you’ve stopped for snacks, there’s never really a good time for your car to not start. It’s usually indicative that your car needs some kind of repairs, and even when it doesn’t, it creates a serious logistical challenge on your hands.

What do you do when your car won’t start? After calling roadside assistance and getting you and your car to a safe location (preferably an auto shop), you’ve got to figure out why it’s not starting. Here are ten possible reasons why your car won’t start.

1. Bad or dead battery
The most common reason cars don’t start is a dead or faulty battery.1 Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire.2 If something’s wrong with your battery, your car engine won’t turn over. There are other symptoms that may indicate a dead battery, but checking if your engine turns over at all is always a good first step.

The good thing about dead batteries is that you don’t need a professional to get your car going again. Jumping a car battery is something that anyone with a base level of know-how can accomplish. Battery jumps are temporary solutions though, and new batteries can be expensive, so it’s best to just take good care of your battery. For more on how to do that, check out these tips for avoiding a dead battery.

2. Bad alternator
A bad alternator goes hand-in-hand with a bad battery. The alternator recharges the battery and keeps the car’s electrical systems running after the car has started. If you’ve got a bad alternator, you don’t necessarily have a bad battery, but you certainly might not have a functioning one. Any bad alternator should be replaced, so be sure to look out for any signs of a bad alternator.

3. Starter motor
Dead batteries or alternators aren’t the only things that can stop your ignition from functioning. If something is wrong with the aforementioned starter motor that receives the electrical signal to crank the engine, your car may not respond to the turn of your key.

Common symptoms
One of the easiest ways to tell if your starter motor has a problem is to check if your lights come on when you turn your key in the ignition. Turning your key turns your battery on, so if you’ve turned your key all the way and the lights come on, but the engine doesn’t turn over, your starter motor could be the culprit. Any signs of electrical failure could also indicate the starter motor needs help. Repeatedly trying to use a starter motor that has been subject to a blown fuse could cause it to overheat and emit smoke.3

4. Bad ignition switch
The ignition switch is another step on the road that leads from turning your key to starting your engine. It plays a crucial role between your battery and starter motor, carrying power from the battery to the engine.

Common symptoms of a bad ignition switch
If you have a bad ignition switch, you won’t hear the starter motor working to start the engine. You also might experience some electrical issues since the ignition switch effectively activates your car’s main electrical systems. Flickering or dying dashboard lights are a prime example. You may also have difficulty turning your key in the first place.4

5. Spark plugs
If your car doesn’t start, it’s possible that its spark plugs are old or dirty. Spark plugs that have become defective in any way can lead to reduced gas mileage, lack of acceleration, engine troubles like misfires, and yes, even difficulty starting your car at all.5

6. Broken distributor cap
It’s not necessarily the spark plugs’ fault. The distributor cap routes power from the engine’s ignition coil to the spark plugs. Broken or malfunctioning distributor caps can cause your engine to misfire, activate the check engine light, cause strange noises, and, of course, prevent your car from starting.6 Make sure there is no moisture under the cap and replace it immediately if it’s broken.

7. Bad timing belt
Your timing belt is another component that is integral to a functioning engine. The timing belt rotates the engine’s cam and crankshaft in unison, causing the cylinders to fire at the appropriate times.

Common symptoms of a bad timing belt
If something is wrong with your timing belt, you may hear ticking noises from your engine, strange disparities in your engine’s revving, or your engine may not turn over. Replacing your timing belt is a piece of maintenance that needs to be performed on a semi-regular basis, so if you notice any issues that could be tied to it, don’t hesitate to call your mechanic.7

8. Jammed steering lock
Ever gotten into your car and found that you can’t even turn your key? If you’ve experienced this, it’s likely that your steering lock is jammed. Your steering lock activates when someone tries to move the wheel while the key is not inserted in the ignition as an anti-theft measure.8 However, it can occasionally serve as an anti-driver measure by accident.

If your steering lock jams, try to wiggle it left and right and then gently turn it in whichever direction allows some movement. Once the lock is unjammed, you can turn the key in the ignition normally.

9. Clogged fuel filter
If fuel can’t reach your engine, your car is going to have a difficult time burning it. As obvious as that sounds, you might not realize that the fuel filter is preventing your car from starting.

Common symptoms of a clogged fuel filter
You may notice an array of fuel-related troubles, ranging from sputtering to poor gas mileage, and, of course, difficulty starting. Your fuel filter should be replaced every 30,000 miles, so if yours is coming up on that milestone and your car doesn’t start, it’s worth checking and replacing.9

10. Empty fuel tank
No one wants to run out of gas, but if you do, the silver lining is that there isn’t anything wrong with your car. If your tank is empty, your best bet is to procure a gas can and give your car the couple of gallons it needs to start, and get to a gas station.

What to Do When the Check Engine Light Comes on

The dashboard of a car is full of mysterious lights that run the gamut from warning to a friendly reminder. Most of these lights remain dark most of the time, and when they do emerge, few people understand all of them. The check engine light is cardinal among these cryptic signals, with many possible reasons for its appearance and more than a few ways to make it go away. But what does the check engine light mean? Despite its varied reasons for appearing, there is an overarching rationale to it, and an important one at that. Understanding what to do when the check engine light comes on can mean the difference between a dangerous mechanical issue and an easy fix at the auto shop.

 

What does the check engine light mean?

Let’s start with what the check engine light doesn’t mean. It’s easy to see a warning light come on and hit the panic button, but the check engine light doesn’t usually warrant immediate concern. If you’re driving along and it turns on, you don’t usually need to pull over and call for help. You should take the light as a sign it’s time to get to a mechanic soon, though. The check engine light is a part of your car’s onboard diagnostics system, which monitors variables like engine speed, fuel mixture, and ignition timing. When that system detects a problem it can’t correct on its own, it responds by switching on the check engine light.

 

What does the check engine light look like?

So, your car’s diagnostics have detected a problem, what are you looking for? A yellow check engine light will appear on your dashboard, though the shape may vary based on the car you’re driving. In some cars, the check engine light literally reads “check engine” and nothing else, while in others it appears in the shape of an engine, occasionally with the word “check”. The light’s appearance may also vary depending on the problem. A solid check engine light indicates a less urgent issue, while a flashing check engine light signals a problem that requires immediate attention. Some cars also show a red check engine light if the problem is severe.

 

Common reasons the check engine light comes on

Engine problems

There is a slew of engine problems that can cause your check engine light to come on. Most are minor and cause your car’s fuel economy and emissions rating to decline, however, some can develop into major issues if unchecked. Engine misfires, for example, will cause poor fuel economy and performance in the short run, but can eventually lead to outright engine failure.

Damaged or loose parts and equipment

Any parts that are damaged, loose or missing will trigger the check engine light. Loose gas caps are a common example of this, though this problem does not pose any serious harm to your car.

Sensor issues

If your diagnostics system detects faults in any of your engine’s many sensors, your check engine light will come on. Some common examples are your oxygen sensors, which measure unburned oxygen in your exhaust system, and mass air flow sensors, which measure the amount of air entering your engine to determine the amount of fuel it needs.2

Transmission problems

As the master of your engine’s power output, your transmission can also trigger the check engine light if it malfunctions. Transmission problems can lead to increased tailpipe emissions.3

Overheating

If your coolant has not been changed properly it can eventually cause your engine’s thermostat to degrade, eventually overheating the engine. If this happens, your check engine light will activate.

 

How long can you drive with the check engine light on?

Many of us willfully ignore the check engine light until we see the symptoms of whatever caused it to turn on. That’s a tempting strategy, but it’s not wise. Your issue may be minor at first but develop into a major problem, as is the case with a bad catalytic converter. Even if the problem is merely reducing your fuel economy, that’s still additional emissions and expenses out of your pocket that a quick trip to the mechanic could fix. In either case, you should have your car evaluated as soon as possible.

 

What should you do when the check engine light comes on?

Turn your car on and off

Turning your car on and off three times consecutively may reset your car’s trouble codes. It’s worth trying this before taking your car in for service.2

Check gas cap

Yes, sometimes it’s as simple as tightening your gas cap. Be patient after doing this, as it may require several trips before the light resets.

Perform a diagnostic test

Many newer cars come with onboard remote diagnostics systems. These systems can report trouble codes and schedule a service appointment accordingly.

Reduce your speed

If your check engine light blinks on while you’re driving, a good first response is to reduce the strain on your engine. Lowering your speed will help. This is especially important if the check engine light is blinking or if it is red, indicating a more urgent issue.

Reduce load

You can also reduce the strain on your engine by reducing the haul it’s carrying. If you’re towing anything, you might want to stop.1

Wait and see

It’s not advisable, but you can always wait and see what happens. Most check engine lights do not need to be addressed immediately, and worsening problems will make themselves apparent. If your car’s situation is becoming more urgent, you’ll probably see or hear the signs.

Visit a mechanic

If you haven’t discovered the reason your check engine light is on, it’s probably a good question for your mechanic. You should take your car in for service as soon as possible.

When to Replace Your Tires

New tires are an inevitable expense, but telling when it’s time to get new tires may not be widespread knowledge to all drivers. Conflicting information from friends and family, from what you read online, etc. may make diagnosing your tire situation a dubious task.

Here are the five telltale signs you should check to determine if you need new tires.

1. Low tire tread depth
To test tire tread depth insert a quarter upside down into the tread. If it doesn’t cover George Washington’s hairline, it means the tread is less than 4/32 of an inch deep, and it’s about time to bite the bullet and get new tires. In many states, just 2/32 of an inch is considered the minimum legal tread depth. However, more tread is safer.

Tests conducted showed a car going 70 miles per hour with tread of 2/32 of an inch took 5.9 seconds to stop and required a distance nearly double that of a vehicle with new tires. Meanwhile, with treads that were 4/32 of an inch, while it still took 100 feet more to stop and 1.2 seconds longer, this was much better than what was achieved with the minimal 2/32 of an inch tread.

2. Tires are old
No matter how rock-solid the tires were when you first purchased them, time leaves its mark. With age, rubber becomes brittle. In addition, the tire’s reinforcing cords can weaken over time. It’s important to know how often to replace your tires. Even if the tread appears intact, most manufacturers advise you to replace your tires after six years.

If you look at the side of the tire, you’ll see the manufacturer’s code. The last four numbers here indicate the production date. If this is 3009, for example, it means that the tire was produced in the 30th week of 2009 and it may be time to get new tires. In more severe climates where you may routinely deal with extreme heat, the ultraviolet rays of the sun may impart structural changes in your tires. This may mean that you will have to make the change sooner.

3. Tire sidewall cracking
Look beyond the tread to the sidewall of the tires. Are there any noticeable cuts or grooves? If so, you may be wise to purchase new tires, since these can be signs that a leak is developing or that the tire is weakening and may soon blowout.

4. Bulge in tire sidewall
If the tire has begun to weaken, sometimes the rubber may begin to bulge. This is a red flag, indicating that the tire has begun to fail and may unexpectedly blow out at any time, putting you and your passengers in jeopardy.

5. Vibrations while driving
Has the ride recently seemed very rough or have you noticed vibrations while driving? If so, this can be a sign that your tires are indeed shot, and it’s time to put aside your skepticism and get new ones.

17 Ways to Save Money on Car Maintenance

Maintaining a vehicle can be expensive. There’s gas, oil changes, scheduled maintenance, new tires, and brake pads, and even the odd check engine light to take care of now and then. If you’re running to the dealership or the most expensive shop in town for every task, you’re spending too much. But you’re also asking for trouble if you’re completely ignoring car maintenance, too.

Properly maintaining your vehicle doesn’t have to be expensive, and done responsibly, you’ll save money on maintenance and ongoing care for your car. You can save on parts, labor, efficiency, and more simply by being smart about how you maintain your vehicle.

We’ve shared 17 ways you can save money on car maintenance. They include changing your own oil, keeping your car clean, inflating your tires properly, and shopping around for a mechanic and good rates on maintenance. Read on to learn how you can be maintenance savvy with these tips and more.

– Take care of car maintenance regularly: Following recommended maintenance schedules, maintaining oil changes and tire rotations, and generally taking care of your car will extend its life and cut down on potential repair bills. Vehicles aren’t designed to be built once and then run forever. They need help, and if you neglect to take care of them, there will be problems. Gunked up oil, low transmission fluid, engine or brake failure, and bald tires are just a few of the expensive messes you can run into if you don’t pay attention to car maintenance. It’s better to spend a little now than a lot later.

– Read your owner’s manual: Yes, really: you have to read the instructions. Your car’s owner’s manual, particularly the section on scheduled maintenance, is a helpful resource for taking care of your car and keeping it in good shape according to manufacturer recommendations. They are the experts in your car: listen to them.

– Do as much as you can yourself: Many maintenance tasks are easy to take care of in your own driveway. Changing out spark plugs, oil, filters, and checking on fluids are all within the skill level of the average driver. By DIYing as much maintenance, as you can, you’ll be able to save on dealership or mechanic labor fees. You may even find parts and supplies for less. Plus, you’ll be able to take the time to check on other upcoming issues for your car, like fluid levels, squeaky noises, and aging hoses or belts.

-Use online tutorials: An essential tool in the car maintenance DIYer’s belt is Google. Get connected with online guides, even YouTube videos that can walk you step by step through common maintenance tasks. You may even be able to find tutorials and videos for your particular make, model, and year, so there will be no guessing how exactly you can access a part or properly measure a fluid. If you prefer to work on cars the old fashioned way, pick up a repair manual for every model of vehicle you own.

Order parts online: Plan your maintenance tasks ahead and get your parts online, where you may be able to find discounts. Often, online parts shopping offers free shipping and better prices than the dealership or auto parts store.

-Never ignore warning lights: Good maintenance means listening to your vehicle, especially when it’s complaining. Any time you see a warning light, pay attention and investigate the cause. It could be something as simple as a loose gas cap, but you’ll never know until you look. Cars equipped with digital odometers make it easy to get trouble codes. Read your manual to find out how to get codes from your particular model, but most can be activated by simply turning the ignition key to the on (not start) position on and off two to three times and then watching the readout while in the on position. You can then Google these codes to learn more about your vehicle’s issue.

-Use a vehicle maintenance app: Relying on dealerships may have you come in for service too early or too late, as dealerships won’t know your car’s exact mileage and when it’s time to perform certain maintenance tasks. With a gas and maintenance tracking app, you’ll enter in your exact mileage each time, allowing the app to tell you about upcoming maintenance tasks you need to take care of right on time.

-Change the oil only when necessary: In the not too distant past, vehicles needed new oil every 3,000 miles or three months without fail. But that’s not always the case with models today. You could be wasting money if you’re changing your oil more frequently than needed. Look at your manual to find out when it’s time to change your car’s oil. You may also be able to rely on digital oil change reminders built into your vehicle’s system.

-Check fluid levels and perform a safety check every time you change your oil: While you’re changing your oil, it’s a good idea to do a quick diagnostic check. Take a look at fluid levels including your brake fluid, antifreeze, power steering fluid, wiper fluid, and transmission fluid. This is also a good time to change out your air filter, check hoses and belts for signs of wear, and take a look at the life left on your brakes and tires.

-Be aware of fair maintenance rates: Charges for maintaining your vehicle, such as oil changes, tire rotations, and scheduled maintenance can vary widely depending on the shop you visit. Make sure you’re being charged fairly by researching rates before you make it to the mechanic. Websites including RepairPal can tell you what you should expect to pay for a particular maintenance or repair task — and can even connect you with certified shops.

– Shop around for a mechanic: A good mechanic is worth thousands — and that’s not an exaggeration. Finding a mechanic with fair prices and honest practices can really pay off, especially when it’s time to make repairs. Read reviews, ask friends and neighbors, and shop around until you’ve found the right mechanic to take care of your car.

-Keep your battery clean: Your battery is a more important part than you might think. And it becomes especially important if you find yourself stuck with a car that won’t start. It’s easy to keep your car’s battery clean. Use a small brush to apply baking soda and water to terminals to clean off corrosion.

-Shop around for tires: Most of the leading tire brands are available at a variety of shops for a variety of prices. You may be surprised to find that big box stores can have the best deals and service for tires. However, some specialty tire chains may have better policies, such as helpful warranties for damage, rotation, and balancing, so consider these as well.

-Keep your tires inflated: Under-inflated tires wear down more quickly and can negatively impact gas mileage. Pay attention to tire pressure sensors, or check manually with a tire pressure gauge. Most gas stations will turn on air pumps for free when you fill up.

-Don’t neglect your air filter: Your car’s air filter can help you save on fuel consumption, as a dirty filter clogged with dirt and debris can cut your fuel mileage significantly. This is an easy fix, as it is inexpensive and usually doesn’t require tools. You should change your air filter about once every three months.

-Keep your vehicle clean: A good wash and wax does more than make your car look great. It protects your paint and prevents residue that can damage your finish and even lead to rust. Regularly wash and wax your car, especially if you park it outside or take it on extended road trips.

-Touch up paint: Like washing and waxing, using touch up paint is a protective maintenance measure that makes your car look great. Using touch up paint, you can seal chips and cracks early on before they have a chance to really become a problem like rust or paint decay.

Top Tips to Take Care of Your Car If You Don’t Drive Often

From cutting out a commute to putting a car in storage for the season, there are plenty of reasons why you might not be driving your vehicle as often as you used to. But don’t let it sit collecting dust — follow these steps to maintain your car and keep it ready to hit the road:

Keep your car covered
If your home has a garage or a carport, consider parking your car inside to protect it from the elements and inclement weather. If your home doesn’t have a garage or carport and you have to park outside, consider buying a weatherproof and UV resistant car cover to protect your vehicle’s paint from accidental scrapes and protect its interior from UV damage.

Take your car for a spin twice a month.
On average, a car can sit unused for up to a month without the battery draining. To avoid finding a dead battery when it’s finally time to hit the road, take it for a 20- to 30-minute drive at least twice a month. This will also allow fluids and oil to circulate and keep your car’s critical systems lubricated.

Keep the gas tank full
While it may seem like a waste to buy gas for a car you aren’t driving regularly, you’ll be glad you filled your tank, as moisture can build up in an empty gas tank as the weather changes, which can lead to damage.

Follow the manufacturer’s recommended oil change schedule
If you’re planning on keeping your vehicle off the road for more than three months at a time, change the oil before putting it in long-term storage. If you’re still driving your vehicle occasionally but you aren’t driving it enough to hit the mileage interval for an oil change, check your owner’s manual to see how long you can wait before getting an oil change.

Check your tire pressure before driving
Your car’s tires can slowly lose pressure, especially if it sits for an extended period. Before driving your car again, check each tire’s air pressure and — if it’s lower than the manufacturer’s recommended air pressure level, which is measured in pounds per square inch — inflate each tire to the correct level.

Regularly check for pests
A sitting vehicle is the perfect home for pests like rodents and insects. To prevent these unwanted tenants from moving into your vehicle, regularly inspect inside your car’s trunk and cabin for unwanted visitors. While inspecting your vehicle, also be sure to check under the hood, as wasps and bees can squeeze in and start building a hive.

Keep your car insured
Cancelling your car insurance policy may seem like an easy way to save money if you’re not driving your vehicle often, but it’s illegal to drive your car at all without coverage — and if you’re involved in an accident, you’ll have to pay for expensive repairs out of pocket. Luckily, you can update your car insurance coverage to reflect the fact that you’re not driving as much as you used to, which could result in a lower premium.

7 Tips to Extend Your Car Battery Life

Car batteries are an essential part of an automobile. From getting your car started to charging your phone on-the-go, batteries provide the zap your vehicle needs to keep rolling. That’s why it’s so important to know when to start considering a car battery change, as well as what you can do to extend its lifespan.

On average, car batteries last between 3 and 5 years. One of the most important factors that affects how long a car battery will last is the weather. A running engine under the hood is already producing high levels of heat. Throw in a scorching hot day and you have a severe drain on your car battery, which can lead to an increased chance of a dead battery if you don’t take proper summer driving precautions.

Warm weather can cause fluid in car batteries to evaporate, damaging the internal structure of the battery. That’s why average battery life is shorter in warmer climates. So when estimating how long your car battery life will last, consider the climate you will do most of your driving in.

Regardless of the temperature you drive in, properly taking care of your car battery can help keep it running. Check out the seven tips below on extending the life of your car battery:

1. Limit Short Rides
Quick car rides prevent your car’s battery from fully charging. Maintain your car’s battery power by driving it frequently and for extended periods. If you don’t use your car often, consider investing in a portable car battery charger. These portable chargers can jump start your battery without another vehicle in case you’re ever stranded.

2. Keep Your Battery Tightly Fastened
A battery that’s not securely fastened could vibrate, potentially resulting in internal damage and short circuits. Have your battery terminal checked regularly – especially if you frequently drive on bumpy roads – to ensure it is tightly and properly positioned in the mounting bracket.

3. Turn Off All the Lights When You Exit
Accidentally keeping your headlights and car door lights on can put a heavy toll on your vehicle’s battery. To keep yourself from forgetting, post a note on your dashboard, attach a sticker reminder on your car remote or park in a direction where you must walk past your headlights to get to your destination.

4. Control the Corrosion
Battery terminals corrode over time but keeping them clean from buildup is a great way to extend the life of your car battery. Scrub the terminals with a toothbrush dipped in a baking soda and water mixture. Then, using a spray bottle with cold water, rinse the mixture off and follow up with a thorough drying with a clean cloth.

5. Test Your Battery Often
Knowing the condition of your car battery matters when you want to maximize its life. Test your battery’s output voltage level with a car battery tester to keep track of how well you’re maintaining it and if you’re due for a new one.


6. Don’t Use Electronics While Idling
Turn off functions like the radio or air conditioner when your engine isn’t running to put less wear and tear on your battery power. Extended periods of idling also can wear a battery down.

7. Care for Your Whole Car
Your car is comprised of many parts working together. Making sure you are taking your car in for routine tune ups, as well as properly storing your vehicle are also simple ways to ensure your battery’s lifespan can reach its full capacity. The battery is just one component of a well-running car, so make sure to properly maintain all parts of your car to extend its life and the life of your battery.

The Right Type Of Gas For Your Car

You might think about it every time you pull up to the gas pump. What grade fuel should I use? Can I just go for the 87-octane the lowest price option? Is there really a difference in gas grade? Here’s what you need to know.

Is a Higher-Octane Gas Really the Best Gas for Your Car?
When it comes to gas for your car, it’s not about which octane is the best but which octane your car requires. If your car’s owner’s manual doesn’t say you need a higher octane than 87, there’s no reason to pay extra for premium gas. A higher-octane gas will not offer you higher performance.

On the other hand, if your car’s owner’s manual says that your minimum octane for your car is 91 to 93, don’t cheap out — it could end up costing you more in the long run. Go ahead and use the premium. The general rule is you should be putting the minimum acceptable octane gasoline in your car as per the owner’s manual.

Why Do Some Cars Require Higher Octane?
Before knowing why some cars need higher octane, it’s important to understand what exactly octane is. When you activate the ignition, this creates a spark that ignites the compressed air and fuel mixing in your engine, which is what allows the gas to power your car. Sometimes this mixture can ignite prematurely, a phenomenon known as preignition, which is signaled by a knocking sound coming from the engine. Modern cars usually have knock sensors that prevent this.

The octane of your gasoline has nothing to do with how much energy is in the fuel. It is a measure of how easily your air-fuel mixture ignites. Higher octane means the gasoline you are using has a greater resistance to preignition. That is to say, it requires greater agitation to ignite it. That is all that the octane level indicates.

Many premium cars generate greater power by using a higher fuel-air compression ratio in the engine. Because the mixture is more compressed, it generates more heat and thereby is more likely to ignite early. Higher octane gasoline is more resistant to this problem.

What Happens if You Don’t Use the Best Gas for Your Car?
Your gas cap or instructions near the gas cap should indicate if your car requires premium fuel. You can also check the owner’s manual for specific information on what kind of octane fuels are appropriate for your car.

If your car requires premium gas and you use a lower octane like 87, you can expect knocking, preignition and engine damage particularly if you have an older model vehicle. If you have a modern car, your knock sensor will kick in to prevent preignition, but this will reduce your engine power and diminish fuel economy, so you will lose more money than you save by using the cheaper gas. It’s also conceivable that your knock sensor could be faulty or slow, which could still result in engine damage over time.

Should I Always Use Premium Gas When It Is Indicated and Never When It Is Not?
Some cars may indicate something like “premium fuel recommended.” What this means is that your car is safe to run on regular 87-octane gas, but there can be benefits from using a higher octane. If this is the case, you may want to just go with the cheaper gas, or experiment and see if the amount you make up in fuel economy and the difference in power is appreciable enough to justify the higher cost of the premium fuel.

What about the other way? Does higher octane gas ever help a car not designed for it? If there is no premium recommendation for your car, putting in higher octane gas will not improve fuel economy, and you are just throwing away money.

If your vehicle calls for diesel fuel, you have a diesel engine, which is an entirely different system. There is no negotiating fuel if you have a diesel engine. You need to fill it with diesel fuel and nothing else. If you put regular or premium unleaded gasoline in a diesel engine, not only will the vehicle not run, you can do catastrophic damage to the engine.

Other Things to Know About Octane
If you are driving through very high-altitude places, you may see gas stations offering lower-octane gasoline than you expect. For example, you may see 85-octane gas advertised. If you are used to always just getting the least expensive gas at the station, you may be tempted to use lower octane gas than you are used to. Here’s why you should resist that temptation.

Older cars were able to operate with lower than normal octanes at high altitudes because of the thinner air, but this does not hold with modern fuel-injection engines. Therefore, if you usually use 87-octane gas, going for the cheapest option if it is lower than 87 is not recommended. It is better for your car to use 87, 88 or even 91-octane gas than to go too low. If you have a luxury car that needs premium gas, try to fill up before driving to a high-altitude location in case you cannot find a gas station that provides the octane you need.

Foreign cars that are designed for sale in the U.S. should have standard octane ratings, but those purchased or intended for purchase outside the U.S. may call for a RON, or research octane number. The RON number and the U.S. octane number do not match up exactly. If your European car calls for RON 95, for example, it requires regular or 87-octane gas. If it asks for RON 98, use premium 93-octane fuel.
