I've also heard a lot about Amsoil and 99.99% was good. So I decided to go that route. The only thing that kind of bothers me is high Ca content that supposedly leads to higher frequency of LSPI events...but the latest news from Amsoil is they should be releasing reformulated SS oils. But that has nothing to do with this tread and probably been discussed 1000 times on this forum. lolGotcha, I'm not against amsoil its good stuff. I have just always been a fan of motul which I already purchased for my civic. I ran it in my 370z and wrx, it performed great in both of those. I have been thinking about giving amsoil a try in my cars, as I have always used it in my bikes. I might try it after the motul, do comparisons on both and see how they shake out.
