There has been a lot about OIL IN THE T44E engine. I do not know all the answers, but at UPS international informed to us ( DO NOT USE SHELL ROTELLA). I have a dodge with a 6BT cum 5.9L in it. I got it used at 289K miles and it was running Mobil Delvac 1300 Super 15W-40. ( Now I worked for Phillips 66 and ran Super HD II 15W-40 for the last 20 years in my dsl engines) I ran an overhead on it and it was SPOTLESS INSIDE. So I decided to give the mobil a try. I ran it for 7,500 miles and gave it an oil change. I droped the filter in the drain pan while I did the change, no big deal, BUT when I went to pick it up I could not hold on to it. I had to get some pliers to pick it up it was just too slippery. This never happened befor. It dit the same thing at 10,000k miles also. I now work for UPS as a mechanic and I have T44E engines. 6BT engines. Cum ISB engines, and mec 904 engines in my fleet. I have swaped to the MOBIL DELVAC and will proberly stay with it. P.S. UPS has used just about all brands of oil for the dsl and the Delvac will run 15,000k miles in the 6BT and ISB engines with no break downs in the engine. most of my fleet is on the verge of hitting 1 million miles on them and the drivers are trained to drive them like they stole it. And they DO.

moved to Maintenance & Fluids

I believe the reason that they don't use Rotella in the T444E is because the old Rotella had aeration issues and it was messing with the HPOP.

That topic (of oil foaming) is so old I cannot even believe it still has life left in it. It was an issue back in 1994 when the first PowerStroke HEUI 7.3 engines first came out. Shell quickly addressed the issue by adding more anti-foam agent to the oil to meet the Ford specs at the time. Since then, the oil industry as a whole has gone through about 5 revisions to API certifications. There are millions of P/S engines out there that successfully run Rotella. There are thousands of UOAs as proof. For quite some time, Rotella and Connoco were the fill lube right from the factory. (I know this, because I visisted the International/Navistar plant in Indy. It just a few blocks from where I worked at the Ford Steering Systems plant. My neighbor worked at Navistar and retired after 32 years; he worked on the final assembly line in the repair area.)

If UPS does not want to use Rotella (based upon a topic that is 16 years old), that's fine for them, and me. There are plenty of good choices in the market, and Rotella is but one of them. If they use Delvac, that is a good choice. But I do NOT believe that it is fundementally superior in such a manner that it makes the pan impossible to pick up with your slippery Delvac-hands where some other product would not (as if that "pan pick-up" was some great measure of lubricant wear protection of implied "slippery-ness" ...........)

Further, and not to be rude, as your post seems a bit of a rambling, but am I supposed to believe that you personally get to choose the oil that is used in the "fleet" as a mechanic? I would suspect, as large as UPS is, that those programs are bid upon contracts, and they look for all maintenance products that meet minimum performance specs (just as most all companies do). Additionally, does your fleet use UOA analysis, or do they just wait until an engine "fails" to find the OCI limit? Because Cummins has specific OCI limits for warranty purposes that come no where near 15k miles in some applications. I would like to think that UPS uses some science and intellect in their fiscal maintenance decisions; perhaps I'm wrong.

Lastly, I've been around many UPS drivers, both on the road in and conversations. I don't recall them ever mentioning being "trained to drive them like they stole it". In fact, UPS has strict rules and regulations for operation in vehicles, and i don't ever recall seeing Big Brown ever significantly speeding or otherwise acting like they "stole it".

Delvac is good oil. So is Rotella and Delo. These 'big three' are the brands that make up the bulk of the consumer market. There are many other capable brands as well including (but not limited to) Castrol, Connoco, Valvoline and all the associated "underling" brand name changes.

Notice I said "old Rotella". ;)

Please read the story again and you will note that you answered some good things, Most had to do with the fact that you skimed the story and did not read it, [1] yes the fomeing was a problem, but the reason UPS still does not use it is because it will not last the 15k miles we put on the 6BT engine. They do not use differant types of oil for differant motors. [2] UPS does not use mobil, I do. and as I said UPS HAS USED ALMOST ALL BRANDS OF OIL [3] And it was the oil filter I could not pick up, not the pan. [4] THE MECHANIC WHO I REPLACED LEFT UPS TO WORK IN RESEARCH FOR IHC. I seems that he could help them fix a lot of the issues they were/ are haveing with the HPOP-IPR- VPR-crank sensor, and primary fuel pumps. As for me I just said that I used to use the # one dsl oil SUPPER HD ll but I have changed to Mobil now. But do not take my word for it look it up on the internet, SUPER HD ll IS still at # 2 now and it has been around for over 40 years

P.S. do not take the drivers word, watch them jump the curbs and drive through the creeks as a short cut all the time brakeing parts off the package cars while doing it.

Oh, I read your first post. In fact, I had to read it several times. I just got lost in the cluttered, run-on rambling style ...

I personally have a great propensity to post long threads and replys, but I try to have the paragraphs and sentence structure make sense. I'm not trying to flame you here, but it is very difficult to follow your thought process in your writings.

Whatever; it's all good if you're happy.
Have a good day.

I just got lost in the cluttered, run-on rambling style .

Maybe it's our READING style...I had the same problem with the thoughts all running together! :think:
