I'm using Amsoil ATf for my 06 Jeep which requires ATF#4.I'm having good service with this fluid.My question is can one brand of Transmission fluid work better than others.Example would be Amsoil ATF#4 to Chevron ATF#4.thanks Joe
 
I think it can... My Transmission in my Santa Fe is very fussy and really likes the Amsoil ATF. The ATF stays clean even up till I change it out at the recommended mileage, I notice less debris on my magnetic drain plug and the fluid always smells like it did new. (no burning). I use my truck like a commercial service vehicle and it's hot all day long and drives in some of the worst weather. I usually get 100K KM's (60K miles) out of the fluid before I choose to change it.

Heat kills transmissions and Amsoil seems to keep the transmission cooler as verified by me with a laser temperature gun pointed at the cooler before/after driving the same place but with the oil being different brands.

The factory stuff would always change colour at 50K KM's (30K miles) even with my external cooler.

That made me a believer in Amsoil and different fluids for my transmission.

I have driven Sonatas and other Santa Fe's that have the same setup as my vehicle and they don't shift as smooth as mine does with 3 times the miles on my truck in some cases.

I have used Amsoil from about 80K KM's until now (320K+ KM's or 192K Miles).

Your choice, but you aren't going to find better transmission fluid that Amsoil IMO.

The AMSOIL fluid is not ATF+4 (as approved by Chrysler), but rather a universal ATF that covers many applications. AMSOIL labels this fluid as suitable for use in ATF+4 applications.
 
Yeah they do the same for the SP-III Spec I require but it works flawlessly and I have proven it by using it for over 220K KM's (126K Miles) without issue.

I hear you though...

Your question is the answer. Amsoil ATF and Mobil 1 ATF are Dex III recommended replacements. Amsoil also has the ATD


ATF

AUTOMOTIVE

GM DEXRON® III-H
• Ford MERCON® & MERCON V
• Chrysler ATF+4®
• Toyota Type T-III and T-IV
• Honda Z-1 (Not CVT)
• Diamond SP II & III (Mitsubishi/Hyundai/Kia)
• Mazda ATF-III, ATF-MV
• Subaru ATF, ATF-HP
• Nissan Matic D, J & K
• Idemitsu K-17
• BMW LA2634
• LT 71141
• Audi G-052-025-A2 & G-052-162-A1
• Volvo 97340
• MB 236.1, 236.2, 236.5, 236.6, 236.7, 236.9 & 236.10
• JWS 3309
• NAG 1
• ETL-7045E, ETL-8072B & N402
• Mopar AS68RC

ATD

Recommended for use in applications specifying Allison® TES-295 or C4, DEXRON® III, MERCON®, Voith G-1363, ZF® TE-ML 14C

Mobil 1 will also work well for Dex III applications, but since XOM makes Dex VI, and Dex VI is backward compatible, they're not going to list it in competition with themselves.

Applications

Mobil 1 Synthetic ATF is formulated for use in most North American, European and Asian vehicles.

I can speak for Mercon V and Mazda ATF-MV that it is physically impossible to meet both specs.

Are they close enough? Maybe.

Will it make a difference in the cars?

Will it make a difference in some cars but not all, even though they are the same model/year?

These are the facts.

However, you can easily find people who "swear by" this or that, and it has been working perfectly for "their" cars, oh for what, 30k miles.

And Redline's, Mobil 1 ATF, and Amsoil are all just snake oil "IF you believe it".

Nothing much in terms of lack of supporting evidence can change that.

I'm betting that most of those atf specs are exactly the same. Car companies don't tend to make there own fluids, they just spec what they need. If there is already a fluid out there that can do the job, just have it re bottled and sell as your own.

I'm guessing Amsoil, Redline, and M1 just have to make a fluid that exceeds the specs of a few of those oils. Manufactures try to make it seem like only there brand is the best because it allows them to sell oil.

Even Mazda has a special 'Dexelia' brand of fluids that is higher end stuff like other synthetics. So even Mazda must feel there is something better out there than their off the shelf m-v atf. I just put in Amsoil, but I would consider the following if Mazda North America Mazda made it available to me.

MAZDA Dexelia ATF M-V
Density at 15 °C 0,861
Color ASTM D1500 Red
Kinematic viscosity at 40 °C 33 mm²/s (cSt)
Kinematic viscosity at 100 °C 7,3 mm²/s (cSt)
Viscosity Index 196
Dynamic viscosity at -30 °C 3 350 mPa.s (cP)
Dynamic viscosity at -40 °C 15 400 mPa.s (cP)
Pour point < -50°C
Flash point (C.O.C.) 180°C
Sulphur 0,06%

So, why is it physically impossible to make a MazdaMV meet the Ford Mercon-V spec, or vice versa?

Which requirements can't be met?

Post the specs that can't be met either way, and the facts.
 
I would like to know the truth between all the different ratings of the atfs. The companies that want your $$$ donot seem to care to tell the consumer.

Agreed. I would vouch for Amsoil ATF though as I have seen it work flawlessly in these Chrysler transmissions for many miles.

Yeah, back in the 90's. Hard parts were the major failure with the Mopar's. Most rolled into the dealer as clunking junk with the OEM fluid in them.

Seeing "Great Wall ATF+4" is approved made me feel warm and fuzzy.

My beat-up car is a 2005 Elantra. I was going to the trouble of finding and buying the approved SP etc ATF for it for drains and refills.

I then looked up the transmission and noted it was shared with some Chrysler products - same clutches, same filters, same part number on the internals. Apparently this is a Mitsubishi design.

So, two cars - one from the Hyundai/Kia group, the other from Chrysler - both of which demand you use only their ATF in it, and yet both have the same transmission.

So, I tried ATF+4 and it works fine.
