Oil Recommendations
#11
Does anyone have any information on the OEM Mopar oil that came from the factory, or that perhaps the dealers use?

I run Amsoil in my truck with an Amsoil filter. For stock trucks the normal service mileage recommendation is 25,000 or 1 year, but if you have mods or tow heavy or any other reason to consider it severe duty then they recommend 15,000 miles. I usually change mine around the 15,000 mile mark. I don't run my truck hard, I only tow about 12,000 lbs 2,500 miles or less a year, but I do have a programmer.

Well at the moment im using delo and running a fleetguead filter. I will be puting a bypass on in the future when it starts to warm up agian. Been thinking of the amsoil. I have that in my 96 dodge and its good stuff. Shell aint bad stuff neither is the mobil delvac. Realy as long as it conforms to the API standards to your engine you should be fine. Seeing as all the brands stated above do I say you should be fine.

Well if you are fueling hard like from bigger injectores and working it hard ex sled pulling, raceing , heavy towing, extended ide time then yeah its a good idea to change it a little sooner. Least thats what I would do.

When I asked the dealer about the oil they use, I was told they can use any brand of oil they want for oil changes, but if they need to use oil for warranty work the oil they have to use is Mobil oil and it has to be purchased from Dodge.

I personally would not run CJ-4 oil in an engine that you have run CI oil in (mileage based) for the exact reason listed before. The new LE oils have lower levels of naturally occurring ingredients then older blends.
I have heard multiple stories and seen a couple of engines that have run CI oil for all there life, when changed over to the LE (CJ-4) oil it caused premature bearing failure do to the lack of additives.
This is my opinion and knowledge based on working with an 18 truck fleet with many shop contacts beyond that. I am not a petroleum engineer!!!!!

Running the new CJ-rated oil in an older engine is a win-win for two reasons. #1, the lower level of "naturally ocurring ingredients" () I believe probably refers to lesser amounts of the old ZDDP anti-wear formulation found in the the CI-rated oils. The newer formulations with their accompanying new anti-wear additives have a slightly lower overall TBN rating. But they have performed as well or even better in many cases as evidenced by a growing body of UOA evidence. Myth busted.
#2, the new CJ-rated oils and their accompanying formulations were specifically designed for much greater soot control capabilities with new dispersant and detergent technology to support much higher levels of soot production from the emissions systems in new diesels. So, you get just as good (arguably better, time will tell) anti-wear performance and better soot control with an engine that produces less soot. Sounds like a pretty good deal to me.
