I found this link for the 50i, but is there a separate service manual for the M50i?

This notes there is an o-ring on the oil filter cover that needs to be replaced. It notes we
do not need to replace the oil drain plug, but only the copper crush waster. It notes oil capacity is 11.1 quarts or 10.5 liter.
It notes the following torque specs:
Oil filter cover to oil sump upper part
-- Oil filter cap
1. Initial tightening torque 40Nm.
2. Slacken 180°.
3. Tightening torque 40Nm.
Oil drain plug on oil sump
1. Bolt size... M18x1.5.
2. Renew the sealing ring.
3. Tightening torque 40Nm.
Can anyone verify the 50i service manual applies to the M50i when it comes to oil changes? I can't imagine it doesn't, but hopefully we can get a tech to verify.
