I've been using Valvoline 75w90 for the transmission and the Subaru STi specific LSD gear oil for the rear diff. No problems with either for 15k+ miles.

Valvoline 75w-90 in the tranny and Subaru LSD oil in the diff.

Advance Auto has it.

Is it ok to top off the tranny with Valvoline? My tranny has always been just a little low, a tiny bit below the low line. I wasnt sure about mixing Valvoline with factory Subaru oil.

i toped mine off with the 75-w90 valvoline about 2k ago and it has been fine. Im going to switch to all valvoline this weekend.

Although good find, I get the impression that web site is slightly biased towards amsoil. I put the Amsoil synthetic gear lube that they used in that test, and it was smooth as hell when I first put it in. 20K later, its real notchy, and I want it out of my tranny. I'm going with Valvoline next time around.

Standard Subaru LSD oil in the rear diff for me.

I looked all over my home town for Valvoline... NG. Advance and Autozone had "Coastal" brand.... which I never heard of. O'Reilys had "Lubrimatic" which I used to use in my 150 hp Merc outboard gearbox for many years without problem. Pep boys, you name it only had synthetic 75/90 GL5, not Dino. Non synthetic 75/90 just doesn't seem too popular(?) in stores.

I went with the Lubrimatic 75/90 GL5 NS. All is good. I was changing out 80/90 GL5 that the Jag/Subaru dealer put in because I couldn't shift it into 2nd when cold.... and cold wasn't very cold like 38 degrees!

Shifts great now. From all I have read 75/90 GL5 NS and Subaru spec LSD oil for dis the way to go.... be carefull not to overfill. Let it drain from both plugs for a while. I put in about 3.7 quarts. Let it sit overnight and then topped off... only 4 quarts to the full line... so some of the old oil must of been left in there, capacity is a little over 4 quarts.

I'm using Valvoline dino 80w90 (bought at local shop, couldn't find 75w90 locally). It worked fine all summer, but at -25C (-13F) it makes for a pretty stiff shifter and there is a lot of drag in tight corners until it gets a bit of heat in it. At -10C and above it was great.

from having experience with stuff like this from different manufacturers, id use what subaru uses. this is just my opinion.
