performance difference in gasolines
21 December 2020, 08:00
I just recently got a 2020 GT (base, not PP2) with the automatic and the manual states it runs on 87 octane fuel, but for best performance to run 91+ octane fuel. My question is, has anyone actually tested and documented results of 0-60 and 1/4 mile ET to see what the actual difference is between 87 and say, 92 octane premium unleaded? Also, would running 100+ octane Avgas provide any more increase over 92 octane pump gas? Just curious as I can't do anything yet since I've only got about 650...
