Subaru 75W90 Extra S Gear & Transmission Fluid - 5 Quart Bottles Sti WRX Genuine SOA427V1700 X5

Perfect for 5 speed manual. Shifts better an slips right into reverse with no notchiness. Yes I said notchiness. Don’t forget the new crush washer.

OEM fluid used in the Subaru WRX 5 speed manual transmission and also in the rear differential. Always nice to be able to use the correct fluid at a reasonable price!

Hands down the best oil for your subaru

Great stuff i changed my manual trans and rear diff with this at 88k miles and less than 500 miles i feel a big differnce in shifting into reverse it would crunch sometimes and now not at all and my 5th gear too goes in smooth happy with this oil will buy again around 30k miles more 👍

People weren’t wrong that this Subaru gear oil is what you should buy to run in your WRX transmission. I had some problems with synchros wanting to grind when trying to shift too fast using different brand gear oils. So far nothing but smooth shifting using this.

I had used STP 80W-90 gear oil in my manual transmission and Mobil 75W-90 in the rear diff (2005 outback). After replacing many other parts, I decided to go the OEM route out of curiosity and wow.Smooth to shift into gear, easy to take off, no more rocking back and forth, no more noises and friction. I am appalled that I didnt trust the OEM fluids first.. Subaru has two engines. Of course they are going to perfect that formulation and they did it well. No complaints other than I was stupid and didn’t buy this first.

I went through a phase using 3rd party fluids, but not worth the time to really do the research. 5 quarts is perfect to do front and back differentials on 2021 crosstrek, twice.

Appears to be genuine Subaru gear oil! Five quarts seems to be enough for two (2) front and rear gear oil changes. Will buy again from this vendor.
