I usually use delvac 1300 or some other that I get for pennies after rebates.

I'm still blowing thru my maxlife 15w40 gallons at $7/gallon from wal mart. Then its HK 10W30 at $7.99/gallon I stocked up on

Already a couple of threads on this. I use it exclusively. You can check my UOA on a a severe duty use. It's excellent HD oil.
