Might look at Royal Purple 0w-40. API certified, meets A3 specs.
My mechanic just filled my Titan's sump with 2qt's RP break-in, and the rest 5w-30. He just installed my JWT cams and springs. I will run it for 1K then dump.
Eneos is getting some good reviews, although it's TBN is a little low, but supposedly, it retains it longer.
If not, run GC. I just bought a few qt's (all they had at A.Z.), for my OPE. If the truck does not like RP, I am going to use GC.
Have a good weekend, I am headed to Crystal River tomorrow for some scalloping over the long weekend.
