I have both 5 gallons of 112 renegade and 3 gallons of 114 Sunoco. The track has gas for a reasonable amount. Glad I am not having to buy it from the local Sunoco store near me. They want $16/gallon for 112!
I plan to mix it to a target of 100 and test there. Will also try some straight 112 again once we have a good base just to see if it helps or not. I suspect somewhere in between 98-114 I will find the sweat spot for my car.
