Octane? Valve timing?

First i was wondering what type of octane everybody uses , now i dont have any "special" racing gas yet , im just talking about the stuff from the pump, so far i've just put in 89 octane. Another thing is the "valve timing" thing , one what do u do, how do u do it and when do i do it , plus could my dealer do it? :rolleyes: thanx

well it helps if you run higher octane because it burns better and cooler also it is better for your motor with the valves you can do it yourself or have a dealership do it for you im pretty sure u do it every couple months

I run 110 octaine, but I used to just run 93 octaine. For the valves just check the EX Tech at the top of the page.
