M1 EP 0w20 for now …
Right now I'm running 0w20 Pennzoil Platinum. When I bought the truck last year they gave me two "free" oil changes...used one. Spent two hours at the dealer waiting...don't think I'll use the other one.
So in one year I have 27,000 miles on it...I've used Pennzoil Platinum a couple times, 0w20 Walmart Super Tech, Napa 0w20 Synthetic and the free stuff (whatever that was) from the dealer. Not sure what my go to oil is going to Ben long term, maybe the Super Tech, it's very reasonably priced and the additive package looks very good.
I installed an oil catch can after 5,000 miles. Don't really know if I'm going to keep it, it catches a lot of stuff but if I don't remember to drain it every couple of weeks?? That would be a problem.
