NoisyBDR Posted March 2, 2023 Share Posted March 2, 2023 Just looking at new oil now I have the gearbox back from Quaife after a service, they recommended using a fully synthetic GL3 or GL4 but not a GL5. Does anyone use Fuchs TITAN SINTOFLUID SAE 75W-80?If so what are your thoughts or anyone recommend anything else? I used to run a Mobile 1 but it has been 13 years since I last refilled it and oils seems to have changed a bit since then. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted March 2, 2023 Share Posted March 2, 2023 Type 9 syncro boxes should use a GL4 grade Redline MTL works very well, GL5 is for final drives, this additives in GL5 affect yellow metals and reduce the friction too much for effective syncro operation.
