Another 5W50 to consider is M1 5W50 which is 4.4

I have run
Castrol TWS 10W60
Liqui Moly 10W60
Mobil 1 5W50
Castrol 5W40
Rotella T6 5W40
Mobil 1 0W40

They all work fine. 10W60 cold start cranking is slow at -10F. 0W40 consumption is high. Somewhere in between is probably a good compromise that would work fine for 95% of users.

Next will be a mix of M1 0W40 and 15W50 since I have a bunch of both.
