What happens if you fill up with 87 gas rather than 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.
What happens if standard gas is unintentionally used in place of premium gas?
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 the 93 octane rating matter?
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
