I been using Valvoline Maxlife- it cured my oil consumption problem. Besides that I'm an Amsoil fanatic.... M1 isn't bad either. Amsoil locally is unaffordable- they charge $14 a quart!!!! WTF

Rotella 10-30. If it is good enough for an 18 wheeler to run, I think my expy will be fine. At $13 a gallon it is a steal.
