any of you guys ever used cen-pe-co oil? its what most people who do truck pulls use. i have a couple buddies using it and swear by it. and i just heard about it. one of my friends said he did oil analysis and he ran it up to 12,000 miles before changing it in his obs 7.3 and he did alot of towing and still looked clean. its 15-40 and cj-4 rated. . its a paraffin based oil and smells way different than conventional oil. he said its about $100 bucks for 8 gallons shipped. so really not that expensive. they have fuel additives, gear lubes, tranny fluid and everything else for heavy equipment
I ran it a few years ago. My truck never drank as much oil as it did with Cenpeco, like 2 qts in 1k miles. I'll never run it again.
They are big into sponsoring truck pulls that's why a lot of truck pull guys use it.
at 180,000+ miles I pulled my valve covers to change glow plugs and everything in there was spotless! I couldn't even get color off of the valve covers with brake clean!
I think I will stick with the synthetic rotella! it is all the engine has had since it's first oil change.
