Daggar said:No it will not. Your wasting money by trying to advance the timing yourself too. Lower octane gas burns hotter and faster than higher octane gas. If your car performs well with regular gas and doesn't ping then you're doing very well. You can start advancing your timing until you do get pinging then back it off 2 degrees and you'll be perfect. Running higher ocatane gas for the sole purpose of advancing your timing is worthless. You will acutally end up with a net loss of HP instead of a gain.
v8only said:great advice. so you think advancing the timing as much as possible on 87 octane, and that's that eh? no 89?
DMAN302 said:I am interested to see if in fact I can run a touch more timing now that the temps are no longer in the 180's everyday. I run premium and 14 deg's...but I'm averaging just over a tank every 6 weeks and with that kind of usage the extra 15$ doesn't hurt as much. I should note both my wifes and my daily drivers NEVER even get to look at the premium pumps.
