Octane ? how high or low
I've read alot where people use way more octane than they really need because a lot of them think that the more octane the faster, and I know thats not true so other than making passes and and going with what runs the best is there a formula that you can go by like compression or what. like what needs 112 or 114 or 116 or maybe I only need 110. I use 114 because the man I bought the car from said thats all he used, but down here around Houston no tracks carry 114 we all mix 112 and 116.
anyway is there a Formula, Thanks Andy
