What Is The Best Gas For Honda Civic?

What Sort of Gas Is Used in the Honda Civic? It is advised that you fill up your Honda Civic with unleaded fuel that is at least 91 octane. Additionally, Honda advises using TOP TIER Detergent Gasoline when it is offered. Never use gasoline that contains methanol and ALWAYS steer clear of fuel that has more than 15% ethanol.

Are premium fuels suitable for Honda Civics?

Can premium fuel be used in a Honda Civic? Yes, technically. However, the engines in many cars are built to tolerate a certain level of wear and tear. Therefore, using premium fuel won’t really make a difference for the majority of automobiles.

Which gas is superior, 89 or 91?


Half of the east coast is experiencing a fuel scarcity as a result of the Colonial Pipeline cyberattack. Due to this, many gas stations are experiencing shortages, higher gas prices, and gallon restrictions.

Many people have inquired as to the distinction between standard grade and premium fuel as some gas stations only carry standard grade fuel due to fuel shortages.

In order to determine the risks associated with not using the proper fuel in your car, our VERIFY team consulted with the experts.


A standard grade 87 or 89 is advised for the majority of vehicles on the road. It’s perfectly fine to fill a normal vehicle with premium gas between 90 and 93. According to auto experts, using premium fuel won’t harm a basic automobile in any way.

Will 87 fit in my Honda Civic?

If you can afford it, you can run any gasoline engine at any time with high octane fuel without suffering any negative consequences. High octane won’t make much of a difference for the majority of cars, but it will make a significant impact for those that are tuned or built for it. Octane has nothing to do with volatility. Some hydrocarbons that are extremely volatile have very low octane numbers. Higher octane fuel does not resist spark ignition, but it does resist autoignition, especially when under pressure. Autoignition temperature and flash point are two distinct concepts. You must not understand diesel fuel or engines.

Does premium fuel make your engine cleaner?

No, premium gas is not a magic cleaner for engines. Carbon build-up is the fundamental issue with engine maintenance and can occur over time with all fuel types if regular maintenance is neglected. The good news is that detergents can somewhat minimize carbon deposits in both normal and premium gas. If you choose premium products, the detergents might be stronger. Nevertheless, having your car professionally serviced is the key to a clean fuel system.

Is premium fuel actually worthwhile?

Why spend a lot of money on something you don’t require? Premium petrol costs around 50 cents more per gallon than regular gas and doesn’t affect vehicles that can’t use it in any way. The Federal Trade Commission warns consumers that, “In most circumstances, using gasoline with a higher octane rating than your owner’s manual suggests delivers absolutely no benefit. It won’t improve the efficiency, performance, speed, or mileage of your vehicle.

In order to clean your engine and improve performance, the detergent additives in your gasoline are significantly more significant than the octane rating. Every shop offers a unique mixture of additives that are applied to all grades. For instance, Chevron’s Techron is available in both their normal and premium gas.

Some people hold themselves to a higher standard when it comes to additives. The Top Tier Gasoline standard, which requires a higher-percentage of detergent additive than the EPA minimum criteria, was developed with the assistance of BMW, General Motors, Honda, Toyota, Volkswagen, and Audi. They contend that lesser detergent additive concentrations may cause greater deposits to form on engine parts like the intake valves and fuel injectors. As a result, emissions may rise and engine performance may be affected. j

Premium Gas Offers Better Performance

This myth is partially true and partially false. The majority of automobiles operate at the same level of performance whether you use standard or premium petrol. You’ll only notice a noticeable difference between the two with particular car models and engine types.

You Need to Use Premium Gas if It’s in Your Car Manual

This myth also rests on circumstantial evidence. Many automakers, like GMC, Ram trucks, and the works, will indicate in the owner’s manual for some of their cars whether they advise or demand the use of premium gasoline. What counts is how these two terms differ from one another.

There are certain advantages to using premium gas when the manual advises against it, but using regular gas won’t hurt your car. It won’t void your warranty in this situation either. Premium gas could potentially improve the performance of these vehicles.

But if the owner’s handbook specifies premium fuel, it signifies the engine does really require higher octane levels to operate properly. Using conventional fuel in these vehicles could potentially harm the engine, and your warranty won’t cover these damages.

Make sure you carefully study your owner’s manual before buying a new or used automobile to make the best decision. Save yourself the money if it’s not necessary.

Premium Gas Lasts Longer

So, is premium fuel more durable? This appears to be a lure of using the ostensibly higher grade fuel for many people. Who among us wouldn’t like to visit the petrol station less frequently?

Regrettably, premium gasoline contains nothing that would extend its shelf life relative to other fuels purchased at the pump. Since the higher octane levels are what set them apart, the only true advantage is a decreased risk of engine knocking, which poses no danger with most contemporary fuel systems.

Premium Gas Cleans Your Engine

This myth is untrue, much like the idea of living longer. The majority of engines are effective in removing residue. You’re in better shape keeping up with routine maintenance checks if you’re worried about the cleanliness of your vehicle’s components.

Can 87 and 91 gas be combined?

Yes, drivers are allowed to mix the two fuel kinds. According to The Drive, the mixture of gas types will produce an octane level somewhere in the center, which the vehicle “will survive.

What happens if you round down to 87 from 91?

Do not become alarmed if the manufacturer of your automobile or truck suggests premium fuel for your vehicle but you instead use normal. Even though premium is advised, you are not required to use it; the engine can run just as well on standard gas.

You can run into issues if you use standard fuel when your manufacturer calls for premium. How well your car or truck will handle normal petrol depends on the sophistication of your fuel system as well as other elements like how your engine is tuned, what the timing is, and how hot it runs. Most of the time, the car will run just fine, although you might notice less power and reduced gas mileage. Because the fuel isn’t burning properly in more acute cases, you might hear engine banging or valve chatter. You should take it to your mechanic because these things might harm your engine.

Does it matter if I’m 87 or 91?

You have the option of using gas with a lower octane rating or gas with a higher octane rating. There are two typical octane ratings: 87 and 91. Just the chemical that they add to the gas is the main distinction between 87 and 91 octane fuel. They still include unleaded fuel that will operate properly in your car.

The additive’s goal is to increase the gas’ resistance to pre-detonation, also known as pinging or knocking. The reason for this is that the gas can only be compressed so far before it heats up enough to ignite without the help of a sparkplug. Pre-detonation may not immediately have an impact, but if it happens frequently, the engine can be destroyed. The characteristic ping or knock sound that it makes, which is absent when the engine is operating properly, makes it quite simple to spot.

Since 87 octane gas ignites at a lower temperature than 91 octane gas, it is more likely to pre-detonate. Try upgrading to 91 octane gas if your engine experiences pre-detonation while using 87 octane gas to see whether the issue is rectified.

The quantity of power that is delivered by 87 and 91 octane is another distinction. 91 octane gas may be pressurized more than 87 octane gas since it does not detonate as easily. More explosive force is produced as a result of compression, which increases engine torque. However, switching to 91 octane gas doesn’t guarantee that your engine will run more efficiently. It still depends on how the engine is built. Keep in mind that the sparkplug’s timing controls when the fuel ignites. Therefore, if the engine is built for a specific compression setting, it won’t compress the gas any farther.

The best course of action is to consult your user manual when selecting the correct gas for your car. If it recommends using 87 or 91 octane gas, then you must do so. The engine experiences issues when using fuel with a lower octane level. While using fuel with a higher octane level may not harm the engine, it does imply that you are wasting money.

Burning of 89 gas is slower.

There are two ways to define octane. Octane is the name of a chemical substance in the purest sense. Gasoline is made up of this combustible hydrocarbon in addition to a few others. It ignites to power the engine in your car. The quantity of energy needed to ignite the gasoline is the subject of the second definition of octane. These octane level values (87, 89, 91, etc.) represent the performance of the fuel as compared to pure (100%) octane as a percentage. Higher octane gas takes more energy to ignite than lower octane gas since the latter burns more quickly. However, this also means that lower octanes burn more quickly and may be more likely to knock in high pressure situations. When gasoline is burning quickly and in high-pressure conditions, knocking happens. Small gasoline explosions take place inside the engine when this happens. These little explosions disrupt the cylinders’ regular action and can harm engine components. Ignoring these knocks may need an expensive repair and drastically lower performance from your vehicle.

Does Honda require premium fuel?
