I ran into this myself having decided to start doing my own oil changes which I've avoided until now due to the mess, but I'm sick of my local independent screwing up my car (various parts not reattached, bonus tools left under my hood, etc.)
I bought an expensive-from-the-dealer MB oil filter a few days ago and found out that they changed to a Purlux brand which uses an even-more-expensive special wrench to remove (unless you use a universal style wrench of course).
Some research here revealed no compelling reason to use the MB version (and at least one impassioned plea to stick with OEM like Hecht or Mann) so the Purlux is going back to the dealer, and four Hecht filters just arrived today from Fastlane.
Ordering from there supports this message board and Phil's customer service is always excellent.
Fastlane/Partshop sells only the official MB filter wrench for them, which looks nice at $25 but requires a 22mm socket to drive it, which is potential extra expense and cumbersome compared to snapping it directly onto a 3/8" drive extension like other wrenches do.
So I ordered the Hazet 2169 from
Samstag Sales, it should arrive shortly. First time ordering from them but they have flawless 2000+ eBay feedback.
By the way, the cheap 74-76mm wrenches at your local auto parts stores don't work. Wrong number of flutes. My $4 loss is your gain.
