I used to be a Rotella user, but experienced excessive consumption in a bunch if diesel engines ranging in size from 7 to 15.2 liters. I switched to chevron delo and not only was consumption cut nearly in half across the board, but wear metals in my oil samples.were reduced by on average 30%. I had one of my drivers come to me and ask what I had done because he no longer needed to add oil to the cat c15 in that particular rig between changes. I have since learned that there's been a shift away from Rotella by many other outfits as well because of the reasons mentioned.

I have a Duramax Diesel in my truck and have been using Rotella T4. I really appreciate you posting this information I will be switching to Chevron Delo. I just learned something new.
I saw this on the Chevon site, it says the Delo 400 SDE is discontinued and has been replaced by Delo 400 XLE B which is a synthetic blend? Which Delo 15/40 did you change your fleet to? Chevron has several Delo 15-40 diesel oils, there is ADF, XSP, XLE and SDE.
