I just love this kind of question.............
The car will hold about the same amount of oil as you get out of it. Many factors determine how completely the oil flows out when drained. The drain plug is at the back of the pan, so naturally more oil drains out in a slight "nose up" attitude, oil temperature determines on how much oil comes out, the hotter the oil, the easier it flows out.
Generally, with a filter change, you would install 3 and 3/4 liters of oil after a drain, you would then start your car up, and run it until the oil light goes out, let it sit a minute, then check the dipstick, and add as necessary.
Turbo cars hold usually an extra liter, but the above instructions will work for you.

You should check the owners manual for the oil capacity, the 1990 Subaru legacy 2.2 will hold 4.5 quarts of oil. I do not recommend putting as much in as you get out as the previous/above poster stated because if you car burns/leaks oil (which older subarus tend to do) then you will end up starving the engine of oil which would be detrimental. And to say turbo cars hold usually an extra liter is not sufficient. You should always check the owners manual or another reliable source. If you have questions, dont rely on the internet (even this post). Check for yourself, call the dealership or order a legitimate owners manual.
Its under the engine, on the drivers side. Two bollts, you cant miss it.

It is located inside the fuel tank, under the carpet, behind the rear seats.
In general, many of the 1990 through 1993 parts are interchangeable on the Subaru Legacys. But your best source would be a 1991 Subaru Legacy, followed by a 1990 Subaru Legacy. Verify the bolt patters before purchasing from 1992 or 1993.

The starter is interchangable between all 1990-1994 Legacies and maybe even up to 1999.

Oxygen sensor on 1990 Subaru Legacy is under car, just behind engine where exhaust manifolds join but before catalytic converter. Wires run up right side of bellhousing and connect into wiring harness.
