Subaru's can be sensitive to what you use in your tranny and diff. I have had very good luck with Amsoil GL5 75w-90 or Subaru's own brand of diff oil. Of course the Amsoil is much easier to get ahold of. They are about the same price. In my 86 GL Wagon, (which I still drive daily) I was experiencing sluggish shifts and lousy cold weather operation. I changed the oil in the transmission to Amsoil GL4 75w-90 and GL5 75w-90 in the differential. Instant improvement. I have also heard that Mobile 1 is also a good choice but have never tried it.
I have a Yamaha 350 big bear, and differential drain plug is on the bottom of the differential. Just remove the plug and let it drain, put the plug back in and fill it back up... i use just regular gear oil
To jack the front end of the 2006 Subaru Forester to change the oil first make sure you are on a flat surface. Then, place the jack behind the front wheel on either side of the vehicle on the frame. Subaru recommends that you use a lift rather than jack the car.

what is the best oil for 2005 outback 2.5
0-20
Yes! Use castrol synthetic oil and you'll all so get better performance and best of all better gas mileage! Don't forget to change the filter.
10 W-40 motor oil can be used in your Subaru, with a minor oil leak. The heavier oil will not hurt your engine and may slow down the leak.
vegetable or olive
5w 30
80W90 gear oil
Use an 80-90wt gear oil
