That is most likely to happen if using regular causes severe engine knock or pinging (premature ignition of the fuel, also known as detonation) that damages the pistons or other engine parts.
If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty.

What happens if you mix 87 and 93 gas?
If you mix a half tank of 91 octane and a half tank of 89 octane, you end up with a full tank of 90 octane. Unless you are driving a car that requires 93 octane, you won’t damage a thing. You aren’t going to damage your engine using a higher octane fuel than necessary, but you will waste your money.
Is it OK to use 87 octane?
Octane booster isn’t cheap – but it’s not outrageous – just about every garage has it. In the case of a car that recommends 87 octane fuel, there’s only one reason not to use higher octane — it’ll cost you money, and probably for no benefit.
What happens if you don’t put premium gas in a BMW?
“There generally isn’t any harm done to the engine by using lower-octane fuel,” said a BMW spokesman, Thomas Plucinsky. “Because our engines do have very good forms of knock sensing and are able to deal with lower-octane fuels, you will not have any drivability issues. You will, however, lose some of the performance.”
Is it OK to mix regular gas with premium?
Save On Mid-Grade Gas By Mixing Regular And Premium. If you put mid-grade gas in your car, it’s actually cheaper to pump in a mixture of premium and regular to get the same octane level. It’s perfectly fine to combine different octane levels of gas, as long as they’re both unleaded.
What cars require premium fuel?
15 Unexpected Cars That Run On Premium-Grade Gas
- Buick Envision. While the compact Buick Envision’s base 2.5-liter four-cylinder engine runs on regular, the available 2.0-liter turbo-four engine recommends premium-grade gasoline.
- Buick Regal.
- Chevrolet Equinox.
- Chevrolet Malibu.
- Chevrolet Traverse.
- Fiat 500.
- Fiat 500L.
- Fiat 500X.
Which gas is better 87 89 or 93?
Additionally, octane levels also reflect the fuel’s burn-rate. Regular 87 fuel burns slower than Premium 91 fuel, which will burn hotter and create more combustion. This is why most day-to-day cars can be filled with regular unleaded, while performance vehicles warrant Premium.
Will using premium gas hurt my engine?
Using premium gas in a regular car will cost you more with almost no added benefits. The Federal Trade Commission says that using a high-octane gasoline rather than a recommended one will offer almost no benefits. It will not make your engine perform better or faster.
Is it bad to mix gas brands?
No, getting gas from different gas stations will not hurt your car at all. You need to consult your owner’s manual about what kind of fuel your car requires. All gas is the same. The difference in some brands from others is the additives.
Can higher octane hurt your engine?
The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. But if the vehicle manufacturer says your engine needs only 87-octane regular, that is what you should use.
Is higher octane fuel worth it?
Unless your engine is knocking, buying higher octane gasoline is a waste of money. In fact, in most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage, or run cleaner.
What happens if you put 91 instead of 87?
Unless it’s a vintage or sports car, if your vehicle calls for 91 and you fill it with 87 octane, it’s likely nothing bad will happen, except the car will be slightly slower and may get worse fuel mileage, according to Edmunds.com. Modern cars have knock sensors that report if the fuel is igniting before it should.
