4..5 QUARTS

Best thing to do is to get the fluids from your local Subaru parts department if possible.
My 2008 XT manual says 4.2 quarts.
Just like changing engine oil only in a different location and with different oil.

Remove the plastic shield marked: "oil filter and oil drain" on the splash guard under the motor.Easy to reach easy to change.
5 quarts
Engine oil capacity for the 2.5 liter is around 5 quarts. A little more when you change the filter, but 5 quarts will do. But then you'll find that out the first time that you change the oil.

4.2 quarts for the 2.5 litre engine. This information comes from the owner's manual. You could determine capacity by draining the oil and refilling until the dipstick reads "full".
