(My Jeep filter is similar, but very easy to install)
Plus, my M240i only needed 5.5L of oil despite allowing it to drain both on ramps and on level ground for 30 minutes. I understand it requires 6.5L of oil?

I don't think you should oil the threads.... If you do so then that affects the tightening torque
