I recently put 2 liters of fresh Ravenol MTF-2 fluid into my 2017 Ford Fiesta ST, 6 speed manual trans (Getrag B6), which specs WSS-M2C200-D2. In the US, Ford uses their DCTF, overseas they use an LV MTF (most likely rebranded Castrol Syntrans FE 75w).
I know that the DCTF is basically an MTF with an AW package, so I'm not looking to compare what I used vs stock; even though I know the Ravenol MTF-2 is slightly higher viscosity (6.1 cst @100c vs 7.x cst @100c, according to the white paper threads).
I happened to look at the spec sheet that Ravenol posts and it mentions, "API GL-4, MT-1". The MT-1 part is what boggles my mind. When I looked it up, it says it's for heavy duty truck transmissions, but the GL-4, I thought, is specifically NOT for heavy duty use. Then when I google, "GL-4 and MT-1" together, I found nothing that links those two together. However, I did find a lot of links for "GL-5 and MT-1", which makes sense if it's for heavy duty use.
Perhaps I'm mistaking their use of "MT-1", idk.... If anyone can shed some light on this, it would be greatly appreciated. THANKS!
