Do I actually require premium fuel?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
91 or higher posted octane premium unleaded gasoline should be used. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
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.
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.

Why do expensive vehicles require premium fuel?
The majority of luxury car manufacturers demand (or advise) premium petrol owing to the needs of high performance engines rather than because they’re trying to be tricky. The auto industry claims that high-octane fuel is advantageous for engines with a high compression ratio. Avoiding “engine knock,” a rattling sound under your hood that lowers your car’s performance, is another issue. Regular fuel with a low octane rating is considered to cause engine knock. It should be noted that the majority of contemporary cars have sensors built in to lessen, if not completely prevent, engine knock.

What happens if you combine gasses 87 and 93?
When it comes to this kind of thing, it’s always better to be cautious than sorry. The answer is that not much happens when you combine 87 and 93 gas.
Regular, midgrade, and premium gas grades are terms used to describe the octane content of the fuel. Those numbers 87 and 93 are measuring the same thing. Gas with an octane rating of 91 or higher is classified as premium gas, whereas gas with an octane rating of 89 or 90 is classified as midgrade gas.
Higher octane gas is generally better for your engine and will produce marginally better performance. On the other hand, you obtain their average when you combine two distinct octane levels.
Then you have a full tank of 90-octane gas if you have exactly half a tank of 87-octane gas and half a tank of 93-octane gas.
It will never be an issue to add higher octane gas to an engine made to use lower octane gas. However, if you use regular petrol in an engine that requires premium, you’ll experience performance troubles.
