I started out dubious of Microgreen, and my test run pretty much confirmed my doubts.
The application is a 2014 Chrysler Pentastar v6, and the filter is an MG1009 as shown on the MG website:
The only reason I even explored MG is because there are almost no premium or synthetic media filters for this application. No Fram Ultra. No Royal Purple. No Purolator Boss. I don't believe premium filters are truly necessary, but since the OLM on this application usually runs the oil out to 10,000 miles, a little added media life wouldn't be a bad thing. And by "life" I mean "calendar days installed" life as much as I mean miles. A 10k OCI can be pretty long for us.
The box proclaimed "made in China," and I almost pitched it then. But the cartridge looked well assembled, no gaps, uniform, etc. so I decided to give it a run. The Microgreen cartridge filter is not like their canister filters with a bypass type filter plumbed in with a standard filter, but instead is just an ordinary allegedly synthetic media cartridge wrapped in a foam "rock catcher" that shouldn't do a darned thing in a healthy engine. The pores are huge and would only stop really big chunks. No benefit, but no harm.. except that it DID do something:
The oil flow into the circumference of the filter enters the canister at the bottom (left) side of the filter, and the flow obviously skooshed (engineering term...) the foam rock-catcher up toward the top (right) of the filter and compressed it. The flow through the main media wasn't compromised in the lower 2/3 of the filter, but was probably restricted in the 1/3. Given that the filter was still very clean, I doubt that it ever went into bypass, but this is still not a good thing to have happen. And its not like the diameter of the filter made it such that it was just squeezed into the filter housing, either, there was plenty of room around the periphery.
The main media itself looked fine:
But my verdict is still, "oh HECK no, never again!" It now has an ordinary Wix cartridge installed.
