Although I searched it was inconclusive...

What other choices other than Mopar do I have for ATF in my 48RE? And I don't trust Amsoil in it while it is under warranty, although I am sure it is a great product. Must be synth, thanks!

MOPAR or AMSOIL. Pick one, AMSOIL works just great and I even had the dealer put it in for me

 

why don't you trust AMSOIL?
not looking to troll, I don't sell the stuff. I put an AMSOIL product in my differential because it was easy to buy online.
Now, looking to put an AMSOIL product in my trans has got me investigating this more.

The AMSOIL brochures show plenty of measurements of fluid properties I have not studied in 20 years (and some I've never heard of...) and the glossy sure makes it look like wonderful stuff. Still, I'm skeptical and curious.

 

What's wrong with Mopar ATF+4? I paid $16.50 a gallon at the local Chrysler dealership. I don't see $4.12 a quart as being too expensive.
I don't know if Amsoil is any good or not. I've read of failures while using it and I've heard of high mileage. I can't conclude either is because of Amsoil because I've also read of failures and high mileage using approved oils. Why doesn't Amsoil get their oils API certified?

 

Amsoil all the way in my vehicles..

 

The thing that scares me about Amsoil is it's universal nature.

I was asking about the ATF for my Explorer, Ford's Mercon V. They state clearly that MerconV can't be compatable with earlier Mercon specs, there is NO universal fluid. One zigs while the other zags. Yet Amsoil claims to be both. I know it's Ford, not DC, but ATF+4 is supposed to be the same deal. Special in some way. And it seems odd that a universal fluid could meet all of these.

 

The universal nature also makes me wonder about the product--no way it can incorporate all of the characteristics of the different products--it simply is not possible, because they oppose each other in levels of certain friction modifying additives. that makes me nervous, and I know DC is not going to honor my warranty if something happens. My PSD dually dropped the tranny at 60K miles never being abused and had to drop 3 grand fixing it, and one of the big reasons I went with a new truck and DC was the 70K warranty. I dont want to do anything to jeopardize that, and HATE buying stuff from dealer. Thats why I am looking for a suitable alternative. I run some Amsoil in my mowers and four wheelers and find it to be a fine product, and am sure it would lead to no problems. Amsoil claims it will pay for something its fluid has a role in breaking--but how long would I be without my truck while we went thru the process of determining the cause of the incident, and hoping I get some reimbursement from them.? I am pretty sure they dont just say well here's the money.....go get a new tranny!

Does anyone have some heat handling characteristics of the ATF+4, and is it indeed a true synthetic fluid?

 

a few quick notes
If the MOPAR ATF+4 is $4 and change a quart, then I think its less than half the price of AMSOILs ATF product.

Has something changed in the last year? I've found old posts about AMSOIL not making and ATF that is ATF+4, and recently these notes that AMSOIL could void a warranty. The AMSOIL brochure clearly says ATF+4 application Chrysler products. That's not enough?

 

Here is what Royal Purple told me when I asked them if their ATF met ATF+4 specs, or if they knew of any others that did:

Matt
You might want to ask Redline to verify that I am correct but I'm
almost positive that the Redline ATF does not meet the Mopar ATF+4
warranty requirements.

In fact the only ATF that meets the ATF+4 warranty requirements is the
one you get at the dealer.



Red Line told me:

C+ATF would meet DC Requirements for my application.

Somebody is wrong...I didnt see anywhere that Redline said ATF+4 for any of their stuff.

Maybe the factory stuff is good, and synthetic, I am mainly worried about this winter in the snow in 4wd at low speeds, etc, and want some heat handling ability. I have 14,500 on my truck now, and I think thats a good time to get rid of the original fluid when I do my diffs. 5000+ miles is towing 6000lbs or more. Adding Magnefine also.

 

Does anyone know for a fact if the Mopar ATF+4 is a full, blend, or not synthetic. I have read on other posts, synthetic and not synthetic. My dealer does not know If you have the answer, do you have source. Thanks.

I guess I am losing patience with hearsay and opinion.

I know for a fact that AMSOIL reverse engineered the ATF+4 to arrive at their FullUniversal since DC is keeping the formulation a secret. This reverse engineering technology is not "rocket science" when your livelihood is lubrication.

Amsoil does more testing and validation than anyone. Their reputation is on the line and everyone scrutinizes them. Just look at the website. No one else offers so much information to help you make an informed and logical decision.

I know Mobile 1 and many other synthetics are good, but do you see a four ball wear test, NOAK Volatility, Kinematic Viscosity Test, or High temp/High Shear Viscosity test at Peb Boys or Auto Zone when you make the purchcase. Check out the Turbo Hydromatic Oxidation Test on the AMSOIL ATF. No one else puts their crank on the line like them.

Back to the original question, what is the type of oil +ATF. My initial thought is any synthtic ATF would be better than fossil.

Some time ago I used RedLINE. I now question, as I have seen them use a Grease Spec to inflate their oil testing spec. and then compared it to AMSOIL. They lost my trust.

Thanks!! IMHO

 

If you are concerned about warranty issues then your decision is simple... just use Mopar ATF+4. None of the other 'miracle fluids' will perform any better and will just cause a potential for problems if a warranty issue crops up. If there's no benefit to using a substitute (and there isn't, no matter what anyone's marketing dept. says) then why do it?

 

That is a complete pipe job if it isn't synthetic. I have heard that it is, but I have no verifiable source.

 

Call Amsoil tech line and pick their brain.They will discuss the Mopar ATF +4 also.1-715-392-7101

 

A friend of mine once showed me the eye-glasses he never wore, they were flat like window panes. He said "I asked a man who sold glasses if I needed glasses, and of course he said yes".

I'd take Amsoil's advice with the usual grain of salt.
