Thanks for posting this link.
It pays to buy better fluids. Thanks for the link.
A dealer did a test with his Ford van running 125k miles in an Action News a while back. I believe he even did some towing. He switched it out to Amsoil syn trans fluid not long after delivery.
He said he switched the Dealer over as an account after the Service Manager saw his trans pan. So this looks pretty good. My dad has 60K on his beater 91 Voyager with a rebuilt A604 trans. I am thinking of letting it go for a fair amount more miles for the heck of it.

Bummer, I would've rather seen Amsoil compared to RoyalPurple, Mobil1, Torco, Neo, Redline, any ATF+4 or DexronVI.
Taking a full synthetic ATF, and comparing it to a mineral blend ATF, just isn't fair. But, it goes to show how 'weak' OE requirements are.

I guess that was a point. M1 would have been nice though. Amsoil tests other fluids (or so I'm told) but the general public doesn't know about Torco, Neo, Redline - so why should Amsoil advertise their names? I'm sorry but this is marketing.....I'd love to see Pennzoil ads on TV mention Castrol!!
no doubt unDummy. Those test results would turn a lot of heads.
OE requirements were just slapped silly in that comparison.

Not at all. This test merely demonstrates how overbuilt the Amsoil fluid is for the application.
I don't disagree that the Amsoil fluid is better, but is it truly necessary? You can put Z rated performance rubber on your minivan that is used as a grocery getter, but is it necessary? Same here.

stupid question... is Merc V better than Dex VI?

Yep, its truly necessary. This is ATF and not tires.
There isn't a transmission made with an overabundance of strength, cooling, lubrication, or filtration.
BTW, higher end tires, even on a minivan, can drastically improve handling and brakeing.

They are different fluids for different applications. It's like asking if a Cummins pick-up is better than a Ferrari.
Its depends on what you are trying to 'pick up'.
I also don't see it as different fluids for different applications. I see it as "the cheapest OE fluid sourced that will make the lifecycle underengineered mass produced within budget component(transmission) last to the end of the warranty with the least bit of hassle(undefined lifetime period) for the consumer".
Its just too easy to upgrade. Amsoil, along with the other boutique companies, are easy upgrades.
There aren't too many applications that do NOT benefit from a fluid upgrade. So, if a synthetic is in the budget, USE IT.

but my point was more along the lines that I was curious if a test of this amsoil fluid against, say, Dex VI would shrink the delta...

I was thinking the same.
Whether it's really necessary is subjective and also depends on the application along with what you are looking for. I put a lot of miles on my cars (that I keep for 3 years LOL) and don't mind spending the extra $ on better fluids. Do I need Amsoil, no but I feel better using it (also PP/M1) for running 10K+ mile drain intervals. I could EASILY use any SM oil and drain it every 5k and still get as good results as I would using synthetic though.
Some transmissions might benefit from over built oils, others won't. Most actually probably don't but you could potentially run 2-3X the OEM intervals using a better fluid. Same can be said with certain engines.
Engines today are producing more heat than ever puttting more demand on the quality of oil.
Someone has to push the envelope.....
Absolutely!!!
IMO, DexronVI and ATF+4 are twice as good as Mercon-V. So, after 1012 hours of testing, the viscosity would be 500,000 cP and not 1,000,000 cP!
The TAN would also be better possibly 600hrs vs MerconV's 300 hours. Pure conjecture
Regardless of brand, you will always see me recommend a synthetic ATF always
How many transmission failures are from fluid problems as compared to poor design "engineered to minimum "
