There are better options out there, such as PP ATF, Castrol Full Synthetic, Maxlife, and all the other synthetic LV ATF's. The new formulas are backwards-compatible with the older specs with no problems
Please explain what "very important standards".
all the modern ones, like Dexron VI, Mercon LV, Honda DW1, Toyota WS aka JWS 3324, Nissan-Matic J/K/S, SPH-IV, that kind of thing
I think your confused about this. Many here believe the better ATFs focus in on a very auto manufacturers requirements. Saying a given ATF meets two dozen different specs doesn't mean it's a superior fluid.
