Thinking about putting in the FX4 next oil change
Amsoil is #1, Royal Purple 2nd, Mobil 1 took home a 3rd place. A guy on the IROCZONE got results from a worker at a Mobil plant. Guess he did a test and proved his companies oil took 3rd.
I'll be using Royal Purple in the Camaro's engine after I rebuild it.. Pennzoil and Castrol would not hold up, gotta move on up to the purp
