just because you can read a msds doesnt make you a expert on how oil performs.

you put ATF in ur 5-speed?anyways... I use the RP synchromesh in my trans. I had mobil 1 synthetic ATF and didnt like it (too notchy), the RP cleared that up but made it a bit noisier. Its not like ull notice much of a difference, but those are the few i did. who knows.. what i do know is that royal purple products are good products and are the only kind ever gonna be used in my car because i feel like its the best and thats all that matters![]()
