Is it OK to mix unleaded with premium?

What happens if you put 87 gas in a 91 car?

If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.

Is there any benefit to using premium gas?

If your car doesn’t require premium, fill up with regular. In a consumer notice, the Federal Trade Commission, notes: “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.”

Does premium gas clean engine?

Nope. Regular, plus, and premium gas all come with detergents to mitigate against carbon deposits in your engine. Plus and premium don’t come with special powers for cleaning out the engine. If you’re interested in cleaning out your engine, you’re better off taking it in for service.

Does using premium gas make a difference?

Raising the octane rating (also known as the anti-knock index) doesn’t change the energy content of a gallon of gasoline. A higher octane rating indicates greater resistance to knock, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.

Will regular gas hurt a premium car?

Because regular has lower octane, it is more prone to detonation. Burning regular in an engine designed for premium on a long-term basis or under heavy loads can cause engine knock, and that in turn can damage the pistons, valves or spark plugs.
