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

I run Shell Rotella T-6 in my 5.9 because it is a superior oil and right now they have a discount/rebate going on.
