As far as capacity, it has a drain and fill plug.
So go drive it for like 5-10 mins, then jack and stand, drain oil, then fill until the oil level reaches the fill plug.

Also, its gunna be way easier to fill if you have an electric transfer pump because theres pretty much no room to pour from a bottle
