Does anyone know what causes the engine knock/rattle sound when you are accelerating? I used to only hear it when using 87 octane fuel. After a few years it started knocking when using 89 but now I'm starting to hear it with 92 octane. The engine runs fine except for the knocking while accelerating. Is there a way to fix this?

Thanks for any advice.
