Subaru used to make a GL-5 MTF, but their newest fluid is believed to just be "plain" GL-5.
Subaru manual transmission owners are still hungry. Mola, we need your help.
Why would you think that when Motul calls the Gear 300 a "transmission lubricant" and states that it is "for synchronised or not synchronised gearboxes" that this would be false? Unless you're believing the "GL-5 is for differentials" nonsense that seems to be out there.
Did you read my quotes from MolaKule above?
And let me state this for the nth time, modern GL5 lubricant formulations are safe in most components/units. When there is a mismatch, it is usually a mismatch between viscosity and friction modification."
I would think that if he no longer believed this statement he would say so and offer science to back up why. But if anything the quality of synthetic fluids are even better now that when he wrote that.
It's anecdotal but I know a lot of Subaru STI owners who have successfully used the Motul Gear 300 for years.
