MOPAR HD 15/40 Motor Oil

[roperteacher]

Visited the dealer today and they still stock the MOPAR 15/40 HD oil that is CI4+ and NOT CJ. Any idea who makes this stuff? I didn't see it in the results of the study unless I missed it. $16 a gallon. A little higher priced but not bad as I thought!! Since all I could find is CJ maybe this will be good?

 

[JHardwick]

I think you are stressing yourself out over nothing. CJ oil is all that will be available soon, and my oil samples show good results so far with CJ4 over CI4.



What is the difference really between the "best" oil and "marginal" oil?



I have 320,000 miles on my truck and I'm shooting for 600,000 miles anyway.



How many of the everage Cummins owners will even come close to that? Most people see 100,000 miles as the "majic number" to trade, and I'm thinking you could run a Cummins on corn oil that long!

You're running nearly 100K miles a year - nearly 7K miles per month , and probably following a pretty regular maintenance schedule, and the engine probably doesn't see much non-running cool-down time. Hardly a typical user or useful as to lube performance in situations the vast majority of us face.



Try running at the more typical 1K per month most of us see - with LOTS of short haul stop-and-go use, you know, the operation that really tests the additives in the oil - THEN get back to us on how the new stuff works for you!



Your situation and annual mileage simply doesn't test the oil additives in the same way most of us operate...

I didn't buy a 1 ton diesel to grab a gallon of milk from the corner store don-cha-no :-laf



My truck runs weeks at a time depending on the weather, A/C in summer and heat in winter. I actually have a very low MPH average because I idle so much ... ..... even at over 300,000 miles!



I see what you are saying, but I still think that a hype is being made out of this CJ oil deal. How many Cummins owners are really going to see the difference when it comes to needing rings and bearings due to normal wear?



I bet less than 5% ... ... ... ... I hope to see a rebuild date, but heck, that'll be close to a million miles!!!

Have asked one dealer in NV. & one here in Ca. who might supply the Mopar brand engine oil and got the answer Mobil 1. I do not know how accurate this is. ?

Just throwing out some thoughts... not directed at anyone:



CI-4+ would handle this type of driving better than CJ-4??? How much better (and why)?? Is it measurable with a UOA?



My UOA of CJ-4 was probably 50/50 mixed driving (not going to repost it, you've already seen it)... some with 90+*F temps towing a small trailer with the slide in camper loaded (trip to Key West). It had a lot of my 106 mile commutes in Philadelphia/Reading area traffic. It also had a trip to MN (and cold started) in temps at -5*F. This is probably the widest variance any one single owner could put on their truck, and the UOA was far from scary at 10k miles...



I just don't see what is scary about the CJ-4 oil... I'm going to see what Blackstone recommends when the 10k mark rolls in, but I doubt it will be a "change immediately" call.



And how extended do we need OCIs?? The DODGE recommended OCI is what? 15k?? If the oil can go 15k without issue, why are we hung up on extended OCIs in *our* little world??? I understand a OTR truck that wants upwards of 50k on a OCI, but does it really affect us and have we actually seen proof the oil (combined with ULSD) can't go that far??



Again, just some thoughts...

I have heard it is relabeled Valvoline (DCX uses Cummins recommended filters, why not use Cummins recommended oil too??)...

That would sound logical.

I went to a different parts store today WAY across town and found 6 gallons of the Mobil Delvac 1300 15/40 cI+4. Not CJ. It was on CLEARANCE ( Probably to make way for all the CJ stuff) for 8. 00 a gallon. SO I bought all 6 gallons. I triued to remember how this oil was rated on the TDR study but could not remember. I just knew the CJ's were all at the bottom of the list and it was not a CJ. SO it is atleast " Satisfactory"... John Holmes recommended switching to synthetic for sure as recommended by cummins engineers but keeping the same drain intervals. .

I would imagine the bottom line question is, WHAT additives have been removed or modified in the CJ lubes, and what was their long accepted purpose - and THEN, what steps have been taken by refiners to make suitable substitutions to make up for what WAS modified or removed.



Find the answer to those questions, and then your own will be answered as well...



IF those additives removed or modified were NOT replaced with acceptable substitutes, why were they in the oil to begin with?



We were either lied to about the effectiveness and "need" for those lost additives from the beginning - or else we're being lied to now - I wonder which it will prove to be?



AND. like many other issues, a longer test period and a few season rotations will be needed before a proper judgement can be arrived at - and it WILL eventually be revealed...

Ahh heck, just add some liquid ball bearings to your engine :-laf



Well, I for one plan on getting as close to a million miles from my motor as I can, which puts me in the minority, and I'm not afraid of CJ oil

 

[Jeff Knight]

I even put the Valvoline Premium Blue CJ in my Kubota tractor. I have no problems putting it in my truck. I even have 3 gal on the shelf waiting for my next oil change. I change mine at 5k. Jeff

I think I am going to have massive head trauma from this topic!! LOLOLOL I just want to do what the best for my truck and it seems like it is going to be a " Wait and see" :-laf

Yup - that about sums it up for me as well - and many others it seems, judging be the various threads on the same subject and member comments. I don't expect any catastrophic issue with the new stuff, especially with normal recommended oil changes - but like others wanting the best for my engine, and suspecting that the "best" is now being taken from my reach, will be looking tor the "best" remaining alternative.



So far, it seems my best solution will be blending my remaining supply of CI4-Plus with whichever of the new CJ stuff that analyzes as best...

 

[Heavyweight]

Roperteacher,,,, Delvac 1300 is excellent oil. No worries there.



There is a walmart in Folsom CA, that still has Delvac 1300 in CI-4.

I loaded up on this stuff.

You'll never put enough miles on your engine to know the difference.



People hate change ... ... ... the 24 valve wouldn't work ... ... ... . the common rail wouldn't work ... ... ... . it's all change, and people don't like change.



Heck, can you remember the "total crisis" when they took lead out of gasoline?



I'm still running CJ oil 15,000-20,000 towing miles without wincing, regardless of the hype or urban legend

AH - but the 24 valve engine DID have unique issues - remember the VP-44 and MANY LP failures?



The common rail too had issues of the type feared - injector problems have sidelined their share of trucks - not as bad as Ford - but LOTS more than the earlier 24/12 valve setups.



That lead-free fuel also created all the premature valve failure issues as was predicted by the paranoid crowd - how soon we forget!



Most here will willingly embrace "new Technology" - as long as the price of admission doesn't exceed the proposed and expected benefit!



I'm not paranoid, "they" really ARE out to get me!



Ignorance may be bliss - but it's still ignorance... :-laf:-laf:-laf



All in fun guys - no offense intended...
