Been useing Dello 400 15-40 in my 2005 Chevy Duramax,is there sometingg better for the same price or less ? been getting it at Costco in the 6 one gallon jugs for $58.00.
GONIFF said:yes the doller is in the toilet,look at the price of Diesel now over last year . anyone ever do a head to head test of Dello vrs Rottela ?
"Yup - that's good humor there!
Back on track: I don't see any real performance differences in the big-3 (Rotella, Delo, Delvac). Each oil behaves slightly differently, but all do very well. And keep in mind that most people here don't apply good analytical controls to their UOA's; they hop from brand to brand, praising or cursing brand "X" with little, if any, good reason.
If price is your overall concern, just buy one of the three you find on sale at OCI time. If UOA's are your main concern, pick one and stick with it. [/quote"
I agree with you to some extent, but you are generalizing a bit there for sure. I certainly wouldn't say "most" people on the board act in this manner, on other diesel/performance/automotive related forums maybe. But not this one. Might be an idea to keep your opinion of "what you think others are doing/have done" without any proof toned down.
