royal purple race11
 

Hea guys, I ordered some royal purple race 11 for my 02 gt because it is 5w20. But i got to looking and it says race 11 is for exotic fuels like alcohol but is this just "extra" protection IF you run alcohol and will work fine on gasoline? what series of royal purple do you guys run in mod motors? (i wanted to stay with the stock weight because my car has only 10000 miles on it and i assume everything is still "tight")
