The lower VI correlates well with the higher flash point. I would guess it contains less polymer than the rest of them.

Because Amsoil uses zero viscosity index improvers. (VII's)

To obtain a multi-transmission fluid?

I see. So that's means it will work on more than one platform then.
Thank you Pablo

I think that must be part of it. Certainly when Amsoil ATF was being developed 25+ years ago the VII's were not even close to stable and Amsoil probably didn't want all those negative effects built in.

See responses like that are why you just use the officially licensed fluid, not a fluid that is a jack of all trades.
Let alone the fact that Dexron/Mercon fluids are thicker by comparison to ATF+4, and contain less friction modifiers then ATF+4, and contain vastly different additives then ATF+4 by license spec...
A low viscosity index means its often a poorer base stock oil. A lower viscosity index will mean it requires more viscosity index improvers (VII's) to function. Amsoils fluids definitely use VII's, don't kid yourself.
Use Amsoil if you want but Pablo seems to have only enough skill to know "Amsoil must be better because its Amsoil". You've been warned otherwise by me, others, and the rest of the Dodge community.
You're not getting a better fluid with Amsoil. You're getting an untested, unlicensed fluid that is well marketed, costs more, and has nothing else to show for it.

Responses like what? Success stories?

This is simply not true. Dexron fluids are lower viscosity and the earlier versions typically sheared to low viscosity as the VII's broke down. The FM's aren't so different and the additive package certainly is not "vastly" different.

Actually you are talking out your hat. Have you ever actually seen the viscosity index of a "poorer base stock"? Yes indeed, they need a lot of VII's. And how functionally are these VII better in a formulated ATF? Lastly Amsoil ATF does NOT have VII. It just doesn't. I'm sorry that bothers you.

So far, how many failure experiences have you read in this thread? None. So your way around this is to insult me. Great. Dude, if you don't like Amsoil, you don't have to use it. You are certainly welcome to express your opinion, but what you accuse me of doing is ironically what you are doing. You really don't have any evidence that Amsoil harms Chrysler AT's so you hurl insults.

Untested? You might actually want to research that one a bit and get back with us. Nothing at all? That sucks.

The Chrysler transmission most sensitive to fluid variations was by far the electronically controlled front wheel drive transaxles found in their minivans, etc. ATF+4 was designed to work with that transaxle's sensitive control system and slip detection, etc. For simplicity's sake, ATF+4 was then specified for the rest of the company's product line, including rear wheel wheel drive transmissions and power steering fluids, etc.
Amsoil has tested and found their universal ATF performs excellent in place of ATF+4 in these demanding FWD units. My experience has been the same in 2 different vehicles. Would I put it in a newer one under warranty? Probably not so as to avoid hassle in the event of a claim. I would not hesitate at all to use Amsoil in your vehicle. I have put it in several RWD/4WD Dodge Ram and Durango trucks and had excellent results and long fluid and transmission life. Check the front band adjustment if you service one. Is often neglected and seems to often be needed to keep 2nd gear shifts smooth and timed well.
And just because it does not have a high viscosity index as other fluids, does not mean it is in any way inferior. A high viscosity index of a new fluid in no way reflects things like shear stability down the road 50k miles or the fact that it has much higher resistance to heat compared to those other fluids. I'll take the heat resistance and shear stability any day!

Nothing bothers me about what you said. If I sold Amsoil I'm sure I'd recommend it to everyone, and Amsoil only has one real offering for ATF.
And when all you have is a hammer everything starts to look like a nail

Have you even looked? Anyone with 10 seconds and web access knows you are ignorant, lying or just trolling.

types....I have been guilty to a certain degree, but to discredit you and not challenge you on whether your knowledge is correct or incorrect deserves the
award of the week.

RiceCake;
You do NOT speak for the Dodge community. The Dodge community would tell you that premium universal ATF's like Amsoil and Royal Purple work excellent in ATF+4 applications.

After 25 years and new technology, why not take advantage of some of the new additives out there?
