but once again...how does that even produce more power? and still it doesn't seem like higher octane fuel would even matter... since higher octane fuel was intended for when the engine runs hot *compression = friction = heat = pre-detonation similar to that of a diesel* and considering that all your doing is changing the timing of the spark...which will detonate the fuel regardless of the octane content. so really i don't see how this would increase power.

and to back up my statement i just read the article on howstuffworks.com about octane ratings and even they mention that the purpose of higher octane is so in a 4 stoke engine the fuel does not pre-ignite during the compression stroke. and they only ever mention having higher octane in a higher compression engine so that it does not pre-ignite. if you wanna read the article to know i'm not BSing
