Have always used rotel in my 7.3 ford but the mobil is a good price right now and I havn't changed yet. Don't put many miles on a year(2500), but change every fall. [Reply]   [No Email]

I don't think you're really going to find much of a change one way or the other myself. Rod [Reply]  [No Email]

When I was rebuilding engines, you could always tell a Pennzoil engine because it had a grey waxy sludge inside! [Reply]  [No Email]

Better oil controll, and more oil pressure. Guido. [Reply]  [No Email]

As long as it's a decent quality oil it should be fine. I've been using Rotella in the diesels, but wouldn't hesitate to switch to something else. [Reply]  [No Email]
