Diesel Oil.....
2006 Cummins 5.9 - 150k miles. I know nothing about this 5.9 that I just bought, except it really runs good. I've always used Delo 400 in diesel engines, what do you prefer and why? Thanks

Update: Went to three Walmarts for Valvoline Diesel oil, they all had none.
Went with Rotella instead.
