The fleet data I saw when Amsoil was field testing their DEO/5w-40 was that wear rates were comparable to AME/15w-40, but OCI's were reduced by 15%-20% with 500 ppm sulfur fuel.

It's sad that this thread has died.

OK, TBN appears to reach its allowable minimum a little faster with the CJ-4 formular. But can anyone provide data on TAN build up and corrosive wear?
Been using EVER-SEEZ and Neverseal on all my stuff - I got it for free!

Not to any significant detail yet Jag...just one off stuff here and there. A lot of folks in fleets I work with are staying the course with dino cj-4 for a while because they don't have the cashflow to buy the even more expensive synthetic formulations. I did here of one operator of mine who is ready to try some Delo 5W40 vs. some of the Amsoil formulations. I need to get my data vampire into that project for sure. Will let you know if I see anything soon...if diesel prices continue to decline then there will be some folks back in the lubrication hunt. After talking with a few of my fleet guys they are saying that if diesel hits $3.65/gallon they are locking in a full year's supply that day!! We'll see if this price point ever materializes this year, but I thought that was pretty wild.

Any feedback on that Delo 5W40 yet?
