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

"Neighbor uses Amsoil in his old 5,9 Cummins Diesel and changes it once a year regradless of miles."
I do the same with my 99 Tahoe with 235k, runs great. I use the AMZ/OIL 15-40 Diesel Marine.
