Re: Which AMSOIL Synthetic for an '02 ?
I am not considering a 5
The two oils in question are both 15
W-40. They are two different synthetic versions made by AMSOIL.
I'm trying to figure out if there is a benefit to the more expensive synthetic version marketed towards 2007 and later vehicles.
Ok any particular reason you are eliminating 5w40 oil?
Either one will work fine.
Ci-4+ oil lend themselves to longer OCIs due to higher TBN
numbers but the CJ-4 (post 2007) will do better against soot. Either one will work fine, I would just run whichever one is cheaper.
