I'm going to affirm Y2Kimmel's idea!

I made mine from a hard plastic 3 gallon container and lid from "Home Depot"
[Duck taped the small hose from the "Rigid" 12 gal. vaccum to the top of the
plastic lid . Since I already had the Ridgid the total cost was nil.]
I "Got Creative" under duress changing the oil in a Marine setting with no
access to the oil pan drain plug.

If you are a Diesel Mercedes:
As for OIL Delvac 1 ( or Mobil 1 "Truck and S.U.V." [Delvac 1 in 1 qt. containers])

If you are a Petrol Mercedes:
Mobil 1 ( of the proper weight)

The whole smoose about "Extended Performance" IS MARKETING.
amongst the "Mice Print" you are advised to EXTEND your oil
changes only after the WARRANTY has expired.

That said I would feel no shame or concern running a new C.D.I.
10K miles (or more) between oil changes using Delvac 1 [with
oil anylsis at each and every change] even under warranty!
