Mobil 1 synthetic in the FX and Castrol GTX natural in the RX-7, Mobile 1 filters on both and they're the same size!
Where's the Amsoil?
Did not see that, Amsol does come up as "Best Oil" on google search. But according to them, they've done this test 2nd year in a row. Maybe next year they'll include Amsol. I'll ask what they think they next time I'm there.
Mobil One for me - 5W 30.
I'm gonna try Royal Purple. I'll get Precision Z do a 2 runs of Dyno and then change my oil to royal blue and try the 3rd run. I was told by a few people that it acctually shows up on dyno![]()
Ionno... sometimes I think these things are propaganda paid for by the winning brands. I've seen tests somewhere that showed Royal Purple actually being horrible on the motor even though it frees up a few ponies. To each his own, but I've seen "completely independent tests" show different results also. My biggest gripe with this is what I already talked about with RP showing baaad wear in certain categories. I'll try and dig up THAT research so that you guys can get a wider-based OPINION on the best oil since I have yet to see solid info that corroborates said results.
