When the filter is completely full, and the filter media is completely soaked, half a quart (maybe a bit less) seems plausible. Like I said before, I think Subaru put the engine's oil capacity in the manual, without accounting for the filter's capacity. I have no idea why.

Seems like people on here and other forums have emailed SOA asking about it a few times and they always reply that it takes more than 4.2 with the filter. Maybe you should email them specifically about the 2.5i for this thread since everybody else has been talking about WRXs and Foresters. I don't see why it would be any different though since the N/A Forester mentioned in the quote above uses the same engine as the 2.5i.

I guess it's kind of like saying the gas tank hold 15.9 gallons, but that doesn't account for the extra little bit of gas that could be in the fuel lines. *shrugs*
