What is the highest octane available in your area?

Btw octane is basically how fast the fuel burns, higher the octane the slower it burns...if you run too low octane it will ignite from compression rather than the spark (detonation), which is very bad for the engine. Under heavy detonation your engine may only last a few seconds...

I hate to be a stickler but it isn't how fast it burns. It is the resistance to ignition. Your timing has to be adjusted to take advantage of this resistance. Beyond that your dead on.
