Can higher octane hurt your engine?

The higher the octane, the greater its ability to prevent the unruly type of combustion engineers call detonation. The goal is to ignite the fuel mixture solely with the spark plug, rather than from the heat in the cylinder, to prevent detonation, which can seriously damage high-performance engines.

Can you run too high octane?

If you run too much octane in your engine it won’t run very well because the burn is way too slow. … If the octane is too low, the fuel will burn too fast and too hot which causes detonation and leads to sure-fire engine damage.

Why is topping off bad?

Does premium gas give better mileage?

Premium gas gives you more miles per gallon than regular gas. … In actual fact, you’ll get a greater range of fuel economy between different brands of regular gas, than you will between the same manufacturer’s regular and premium gasses.

Does high octane fuel increase horsepower?

Octane does not offer any better fuel mileage, increase engine horsepower, or make the engine start quicker. Higher octane only reduces the likelihood of engine knock or ping. … Because higher octane gas burns slower, it is more resistant to knock when subjected to higher RPM and cylinder pressures.

What happens if you mix 91 and 95?

It won’t hurt your engine if you use a higher octane fuel. For example, if you use 95 or 98 in an engine designed for 91, that’s fine. However, avoid using a lower octane fuel than the minimum recommended by the manufacturer. Using 91 in an engine designed for 95 or 98 is potentially destructive.

Which gas is better 87 89 or 93?

Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates.
