Can I damage my engine with lower octane?

Use of gasoline with an octane rating lower than what is recommended may result in engine knocking. Persistent knocking can lead to engine damage.

What happens if you put 87 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.

Does performance car need high octane fuel?
