Default differential fluid for 98 Legacy Outback Stick?

What differential fluid should be used for the differential of a stick shift 1998 Legacy Outback?

I had a disaster with dealer service using the wrong kind of clutch fluid a few years ago, and want to be sure i have the right material. A mechanic mentioned GL-5.

Anybody with thoughts on this?

Many thanks...

My understanding is that you can use most any 80w90 gear oil. But stay away from Mobil 1 Synthetic gear oils in these trannys. The high sulfur content in the gear oil apparently wrecks havoc on the gears. The Mobil 1 is OK in the crank case (engine oil) but if you call them up they will tell you not to use it in the tranny.

Alot of people use Redline Synthetic 75w90, but if you do some searching for transmission oils, you will find numerous threads on this subject.

The most common responses in the past have been Redline, Royal Purple, and Valvoline with the synthetics or blends preferred.

I used Pennzoil Synthetic 75w90 from 50k to 100k...it drained as clear as when I put it in...ran it in both the front and rear differentials.

I am now running a mix of 75w90 and 85w140 Royal Purple...seems to have gained a touch of mileage...
