Specifications for several 3309 ATF fluids

[oragex]

I was searching information on several 3309 fluids available and I came to the conclusion that the 3309 norm doesn't necessarily mean that all the fluid properties are identically the same no matter the brand. Without being an expert, when looking at some 'parameters' (flash point, pour point, viscosity, etc) we can notice there are differences between these fluids. I had a not so good experience with Valvoline MaxLife which is 3309 (too much volume change with temperature), so perhaps going with the better brands (Toyota Type IV and Mobil 3309) is the better and safer choice. One interesting thing is that on the spec sheet for the Toyota Type IV, at the top of the page 3, it is mentioned that the fluid is 90-100% mineral, so perhaps this answers an older debate on whether these fluids are mineral or not. And of course, I think most of us recommend to replace the fluid at a certain interval (unlike what the main dealer says), perhaps better by steps at a few months interval, instead of all at once (also no garage machine flushing)

I have been using Toyota TIV for 100k miles with a drain and fill every 15k....no issues.

Idemitsu Type-TLS is the closest match to 1161540. This is probably what goes into factory fill, though I still feel OE has more additives out of the box.

I use OE ATF and add Lubegard HFM when ATF starts to wear out additives.

A weak ago I also poured a 3 oz of evil soviet copper oleate additive that boosts lock-up properties of friction plates, plaques worn metal with copper to reduce gaps/leaks and to stop hydrogen embrittlement of steel https://www.imetllc.com/training-art...tlement-steel/

3309 and type 4 are MINERAL.
For whatever reason Aisin seems to believe it's better than any synthetic for these transmissions

What is JRL's choice for ATF?

Mineral oil has a better lubricity.

Mineral oil has a better lubricity.

Does Lubegard HFM alter that "lubricity" HFM = high friction modifier?

Mineral oil has a better lubricity.

Also, quicker to reach performance temp and then relatively slow to cool off. HOT temp retention is good for working tranny while repelling temp volatility. What is JRL's choice!

A bit: it contains esters, which molecules have a very high polarity.

?? Can you explain that?, sounds too much like, "Because Brawndo's got electrolytes." kind of a thing!
