Putting a Ess g2 kit on my 2019 auto pp1. I drive the car everyday and it gets slight street action only no track at all. Should I use 5w50 or 5w30? Still on stock opgs if that matters ?

Since going boosted, I moved to 5w50 as many have.

Ford recommends 5w/50 for FI engines

I do 5w50 in the summer 0w40 in the winter, or a mix of 5w50 and 0w40. Amsoil signature series. I live in fl.

I’m not boosted but figured I’d add my opinion.

This was long discussed back in the early Coyote days. Numerous analysis reports show that the motorcraft 5w50 very quickly shears down to a 40-30 weight. Running a higher quality 30 or 40 weight will be just as good.
