Quaker State 4x4 synthetic blend ATF for ZF 6AT

[Turkeybaster115]

What do you guys think of this trans fluid for my BMW 335I ZF 6at

Spec sheet: http://www.mil-specproducts.com/Documents\1203_PDS22.pdf

MSDS: http://www.mil-specproducts.com/Documents\1203_MSDS22.pdf

I am currently using Pentosin atf1, for year round/mild track use. It is mineral oil based, and I thinking this ATF would be an upgrade in base oil.

The spec sheets that you list for Pentosin ATF say it surpasses all Dexron III specs by far. Probably because the fluid was made before Dexron VI.

Whereas the Quaker State ATF spec sheets that you list show the fluid meeting the Dexron III spec, but don't show the fluid exceeding and/or far surpassing that spec.

I would be looking at a more modern formulated ATF, such as Dex VI.

I also noticed that the Pentosin spec sheets say that the fluid does not give full performance if it is blended with another formulation of ATF. This seems to indicate that the additive package in the Pentosin is very specific and works best when a full transmission flush is done (this is recommended in the spec sheet). Personally, I would just keep using Pentosin, I think the additive package is more important than the base oil. The Pentosin spec sheet does say that it is fully synthetic, not a synthetic blend like the Quaker State. Frankly, I'm not sure where you think the Quaker State fluid is better for your application?
