Recenly bought a Subaru Impreza 1.5i. I noticed that there is a little dipstick in the engine marked "Diff", I heard it is the gear oil. Now the manual I have is in Japanese so that doesnt help much. Can anyone confirm that it is indeed gear oil and what grade oil should I get?
I run mobil 1 gear in MY02, but yours might be different, have you consulted the user manual? I would try there first, then other sources. You might be so inclined as to call the dealer on this one? What year is the car>?
