I just discovered that Motul is now making a dual-clutch transmission fluid that is compatible with BMW's DCTs and many others. For those who do have a dual-clutch, there seems to be a lot of disagreement or hesitation to deviate from the OEM fluids. "Especially suitable for Dual Clutch Transmission (DCT) supplied by ZF, Getrag, or Borg Warner and used by the main car manufacturers: VW Audi Seat Skoda (DSG or S tronic), BMW (DKG), Mercedes Benz (7G DCT), Porsche (PDK), Ford (Powershift), Opel (DSG), PSA Peugeot-Citroen (DCS), Renault (EDC, DC4), Nissan (GR6)." They list it as meeting BMW specs DCTF-1 (part number 83 220 440 214) and MTF-LT-5 (part number 83 220 2167 666). They also show it as being equivalent to Pentosin FFL-2, FFL-3, and FFL-4, along with Shell TF DCT-F3 which we know is the factory-fill in the Ferraris that use the higher-output version of my transmission. KV @ 40 C = 33.8 KV @ 100 C = 7.3 Viscosity index = 189 Flash = 196 C / 385 F Pour = -45 C / -49 F Full technical datasheet: http://www.motul.com/system/product_...pdf?1358262409 This stuff looks very interesting, especially since it can be had for $20/qt or less (compared to FFL-4 @ $40/qt and the OEM-labeled stuff for even more). The viscosity index is also some 12% higher than the OEM FFL-4 fluid, meaning it should perform better across the entire temperature range. I haven't talked to Joey at Motul USA about this yet, but it's on my to-do list for this week. My car should probably get a fluid change and this stuff is really tempting.
