Purple gas, Sunoco 100 octane stuff that you can get at most tracks. Has anyone ever run it in a Lightning?
I was wondering because I noticed a difference between 92 and 94 octane and the manual says to use the highest octane available. I was wondering if anybody found a limit to that octane level yet.
Before anyone gets up my butt about noticing the difference in octane, the difference I noticed was on a long trip (~1250 miles) was in running temperature and gas mileage. It was a pretty drastic difference of about 10 degrees and 2.5-3.0 mpg. If I can notice that much of a difference, I can only imagine what kind of results race gas would provide in temperature and even power production through better timing advance.
