DCT Fluid in an MT? AKA is Pentosin FFL-3 MTF-LT-5?

[JHZR2]

Ive seen discussion all over the web that states that Pentosin FFL-3 is also the MTL-LT-5 MTF from BMW.

FFL-3 is a porsche approved fluid only, as far as I can see... In fact, that is the only approval that Pentosin claims. But I guess that BMW is the only user of the MTF-LT-x coding.

ZF seems to imply that it is interchangeable.

According to spare part number of vehicle manufacturer: - Pentosin FFL-3
=> BMW Oil No. 8322 2167 666 (MTF-LT-5)
=> Daimler Oil No. A 002 989 04 03 (Getriebeöl ET)

But Pentosin calls it a DCT fluid and only shows Porsche specs/sheets/approvals. It does list the generic ZF document linked above.

So, I have a MT, not a DCT, and BMW is specifying using a DCT fluid? Pentosin states:

Quote:
FFL-3 features a special clutch friction performance which makes it mandatory to be applied solely to the double clutch gear box


Redline claims their DCTF for both the BMW DCT spec and the MTF spec of interest, but I always feel that Redline takes liberties...

So, anyone know of an official confirmation that pentosin FFL-3 is MTF-LT-5? I see lots of commentary and some anecdotes, but nothing official...

Thanks!

Most DCT fluids have the viscosity of an ATF (7.5 to 6.1 cSt) but also contain a pretty stiff MTL additive package with a GL-4 protection rating.

So while I cannot speak to your specifics, it would not surprise me that a DCT fluid would be speced for an MTL.

I researched this myself a while ago. It's real - FFL-3 is MTF-LT-5.

I eventually concluded that the wording in the Pentosin description of use is mangled by transliteration. Properly translated it would say "FFL-3 features a special clutch friction performance which makes it mandatory [for use in] the [Porsche] double clutch gear box". In other words, you can't use anything else in the Porsche gearbox. As for the fluid itself, you can use it in other places as much as you want.

Thanks! How did you confirm? Did you contact Pentosin?

I was looking at alternative fluids for the TR6060 in my GT500, so I went down many paths. If I remember correctly, I found a BMW tech publication that confirmed that the Pentosin FFL3 was suitable for use in the manual gearbox in the 1M. The 1M gearbox was the only application for MTF-LT-5 that I was able to find - all other variants of the same gearbox use a different MTF-LT-x specification.

Documentation from Pentosin wouldn't have been convincing enough.
