I've researched AMSOIL ASL, ATM grp IV, Redline grp V and now Schaeffer 9003 grp III/IV. I've read the UOA's. Out of the 3 which do you think has the best additive package for high performance driving? I'm down to 3 (please, no PP or others) AMSOIL, Redline, or Schaeffer? I know all 3 are excellent but which one would you use?
I think this will help me and our viewers out there.
The UOA's show good and bad on all of them depending on engine condition. Thanks.
