Well, today I'll be mailing off an initial or voluntary oil analysis at 1001 miles on my new 2007 Jeep Grand Cherokee with the Mercedes-Benz OM 642 DE30 LA 3.0L V6. This is just to establish a baseline reading. I don't know what Jeep uses as the factory fill, but the dealers stock MB 229.51-spec Mobil 1 ESP Formula M 5W-30. I've got a case of Amsoil AFL for the initial change, plus two Mann HU821 filters.
Absolutely nobody else makes filters for this engine. I need to find a way to hook up either my old Amsoil BMK-13 Dual Remote filter mount or a new BMK-11 bypass mount, or possibly something else.
Oil supply source usually is the sender port for bypass-only setups, and while the sender is visible up front on the engine block, it is a DIN metric fitting, so I'll probably have to fabricate some sort of adapter. I've looked every for an off-the-shelf solution, but no luck. It looks like it might be 14mm, and I think I have a tap for that (if it is the same as the common sparkplug / oxygen sensor thread).
The return line on the Amsoil BMK-11 uses either a self-tapping hollow bolt in the pan or valve cover or else the optional swivel fitting in the center of the oil filler cap. Neither is an option, since both the covers and pan are cast aluminum, and the filler cap is hollow plastic and is of the "stove-top-knob" style. Still, there is lots of room on the side of the filler neck where a bulkhead fitting might be fitted, albeit with drilling...
Other options deal with machining some sort of adapter for either the oil filter cap or the oil filler cap. We'll see...
