the talk about ethonal in the gas i really would like to chime in on. the theory about the need for more fuel to burn the air when ethonal is involved is correct, but as long as your richer than 14.7 on a o2 sensor calabrated for gasoline, all of the oxygen has been burnt. when you run rich during boost that extra fuel is mearly there to cool the cylender. since ethonal is far superior for cooling than gas the 10-15% will negate itself (always).

now lets talk about octain ratings. if you read at the pump it will say minium octain rating. what that means is it can be higher but cannot be lower than advertised (just like treadwear ratings on tires). your shell gas in your area could possibly be 94 or 95 and when you switch to other brands they might just be closer to their advertised rating.

i have found that the best gas in my area comes from a station advertising it as 92 but it kickes every other stations butt for detenation suppression.


i find it funny most people blame ethonal for everything and try to find gas with no ethonal in it, while i would love to find some ethonal with no gas in it. how can ethonal be the reason i make such good power while at the same time its the reason others complain of trouble?

my best suggestion would be to find the best gas you can, with the most ethonal as you can and tune from there.
