thanks for the info on the mityvac and the link. I did do a search but missed it.

I too was looking at the mityvac at amazon. However, I saw a commercial unit that says it has a bmw adapter included. I wonder what that might be. Does anyone have a guess?

here is the link to the unit:

PBE 9MS A7350 - 8 gallon air operated oil changer

Looks like I could use it for all my equipment.

any thoughts?
