ganito pagkakaintindi ko about octanes... The amount of octane in your fuel determines how far the mixture can be compressed before it pre-detonates. Higher the amount of octane the lesser is the risk of pre-detonation due to compression. And that's about it. Higher octane by itself has nothing to do with more energy or more power or better gas mileage.

so it means that if your car uses a higher octane fuel, the pre-detonation is lesser. so it means, walang carbon residues. dahil ang carbon is a by-product of unburned fuel due to pre-detonation.

to conclude: if you are maintaining and using a higher octane fuel, your engine will be cleaner, although not directly, because of lesser pre-detonation. and that's about it. yung carbon residues naman can be cleaned by doing italian tune-ups once in a while or via the cleaners na meron sa lahat ng fuel.

if your car runs on 93 RON, then its fine and leave it the way it is. if it rattles , its a sign of pre-detonation, which tells you to use a higher octane fuel.
