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 ran Delvac 1300 non-synthetic, then switched to Rotella TTT as it was on sale, but the metal numbers started to climb in the reports from Blackstone Labs. I switched back to Delvac, and all the numbers started to drop, now everything is back where it was before the switch to Rotella. Blackstone Labs said
"While it's impossible for there to be absolutely no bearing wear in 4,599 miles, it is possible for it to be so low that we can't measure it, and that's what we've got here." I went 6,000 miles on the last oil change, and all is still excellent.
Cheap and good oil. An excellent combination. I can generally get a gallon of Delvac for around $13.
