100oct race fuel is typically unleaded, 110 is leaded ...
I ran two tanks if sunoco 100 unleaded at the track thurs... ran it all last year at the track, no issues
Make sure it isnt leaded fuel
When i track my car i try to eleminate KR as much as possible, i run 100oct on a 91oct tune, just for the added safety. Plus at the track, 91oct is 6.99/gal and 100oct is 8.99/gal ... sooo wtf lol
