Hi, I cannot find in the Mercedes Owner Manual the torque specs for the drain plug.
I vaguely finds other mercedes specs online of 30 NM. Anyone knows the real torque spec from the service manual ?

I also see that the oil filter is 25 + 5 NM. What does that mean exactly ? 25 NM and then 5 NM ? so simply 30 NM ?

last question!

I saw that people are doing oil change by pumping out the oil now in some youtube videos? Is this a thing now ? Is this propaganda to sell the pump on amazon ? Is this the new way Mercedes are doing oil changes ? What was wrong with draining oil trough the drain plug ?

Thanks!
