Motul Gear 300 Fully Synthetic Gearbox Oil - 75W90 1L (Pack of 4)

2016 WRX 6sp transmission needs 75w90 without limited slip additive. I used redline previously and it was good. I heard that this is better. It has been 10k since I changed to this and it is better than worn/used redline, but probably about the same as when redline was new. This is a little less money, so I will use it next trans oil change. Smooth and no grinding if you keep good form.

Recommended online on other (Subaru) sites. So gave it a try. Helped with some shifting issues, but I also had to adjust the clutch pedal to get full benefit.Would buy again.

Used 4 qts in my 2009 Audi S5 4.2l B8. Smooth shifts as a result.

Used in the Wife's 2016 Subaru Crosstrek manual transmission and differentials. Shifts seem less notchy.

Go to oil

So I switched back to this from the oem and I had tried it before, didn’t notice much difference. Now with another 50k miles on the car it ended up being noticeable for this go around.Worth the little extra cash.

I used this to replace the factory fluid in a heavily tuned AWD manual track toy. After adding it my shifts were smoother, and the gearbox even made a bit less noise(running solid mounts, you hear everything). I'd be interested to see how it stacks up on the dyno with this vs before.

This 4 pack of Motul 300 Gear Oil was just enough to fill my manual transmission and differential with new oil.. This was the first time I have ever changed the transmission/diff oil on my car by myself (with a friends help) and it really does make a huge difference. The clunky, notchy, sticky transmission I once knew is completely gone and now the car really shifts the way it should have from the factory. The transmission is smooth as silk.Make sure you really clean off the plugs and use new gaskets. After changing the trans/diff oil I let the car idle for 10-15 minutes, then took it for a ~10 mile drive. I can't believe how quickly this stuff works. I highly recommend this product for anyone who owns a Scion FR-S, Subaru BRZ, or Toyota 86. I'll definitely be using this gear oil again.
