For the Rear: Stock LSD oil from Subaru

For the Tranny: Motul Gear 300 75w90..I got mine from ED at Eq tuning.!

 

Subaru Gold Extra S

 

I ended up putting Redline 75w90NS just so we could get it drivable. Gonna switch it out to swepco when it starts to grind and stuff. Thanks for the advice guys.

 

I have used Swepco, SF MTL-R, and Subaru Extra-S. No problem with any of them. Converse to another poster, I actually liked the Extra-S a tiny bit better. Swepco is 80w90 while the Extra-S is 75w-90, and the Extra-S shifted a little bit better the first few shifts when cold.

In summary, either Swepco or the Extra-S will work fine.

Disclaimer: I bought the Extra-S from Bryan! Cool guy!

 

I've used Valvoline 80w90 dino, the uncle scotty mix, and now subaru extra-s. The extra-s is leaps and bounds better than the other two I've used.

I'm using Mobil1 for the rear.. I heard the rear diff isn't picky on which oil. Is this true? I never bothered to change to the extra-s for the rear.

 

About to change my rear diff/tranny fluid as well
