Thanks for bringing up the differences for the N20 motor.
Mywikimotors dot com says the N20 has an engine oil capacity of 5.3 quarts, which is basically what was described above.
Edit :
Just updated original post to include N20 engine quantity as 5.3 quarts.
Please be careful as to not overfill or frothing may occur or drainage issues for the turbo drain may occur .

If overfilled you can loosen the drain bolt and set a cup under it marked with the half quart amount or so you went over. It will drain slow since you would only be backing it off a few threads to create a leak.
Thanks for the feedback everyone!
