Adventures with a Pete 587

[JimT]

I've been using Rotella in my Dodge pickup with the 5.9l cummins for 5 years with no issue. Only thing is it gets black quick, otherwise it doesn't burn any between oil drains. When I first got the Pete I was gonna use Rotella but a local mechanic suggested Delo since, according to him, it's a little thicker and will protect better. Engine also had a label advertising Delo as the factory recommended oil, so I went with it. No problems. I keep it topped up and dump it every 10-13k. It gets black, but it's never ever gotten as black as the Rotella that comes out of my Dodge. Everyone I talk to, who isn't blindly biased, says the same thing, pick one and if it works for you then stick with it.
