I'd run the 040 before the 1040. 0W20? No way.

M1 0-20 is pretty thin stuff- unless you drive in nothern winter temps I wouldn't use it.
Go to AutoZone and get some Castrol Syntec (German Catrol) 0-30
Don't want to start another M1 vs GC war, but it is a pretty good oil with proven oil anaylsis results

I've seen M1 0w-40 at the local AutoZones. I'd recommend the M1 5w-40 Turbo Diesel. It used to be sold as Truck & SUV. It's reputed to be Delvac 1, a well respected HD oil. It's also available at AZ and I've also seen plenty of it at wallyworld, quarts and gallon jugs. I run the GC cause local now AZs carry it, but I used to run the T&SUV b4 they did.
