3.6L Pentastar Oil Filter - First Change

Others have posted about how easy it is to access and change the oil filter on the Pentastar V6, and how the cartridge filter allows easy inspection, but no photos I have seen. Sooo here is my experience with pics.

My dealer set up first oil change at 8,000 kms (5,000 miles), but I bought a filter on the day I took delivery so I could change the filter sooner. So here are my findings at about 4,700 kms.

The change was a snap. Remove the access port in the engine cover and use a 15/16” socket to remove the filter cap, and the filter cartridge pulls out with the cap. The filter then unsnaps from the cap and a new one snaps in. They provide a new O-ring in the box with the filter. Only very minor drips need to be caught by towels or rags when the cap is removed. Very neat.

The oil was medium brown. Nothing unexpected for nearly 4,700 kms, and smelled normal. I took the old filter cartridge indoors and cut it open for inspection. The pleated cardboard is about a metre long when unfurled. I found many small metal flakes in the filter pleats, on the exterior side where they were caught. So the filter did its job. There were about 200 of these small flakes, ranging from pinpoints of reflected light to (0.3mm x 0.1mm x foil thickness) in size for the largest ones. More than I expected to find, but nothing alarming to me. The filter did its job and I will do another check of the replacement filter to see if any more flakes appear on the second filter, before the dealer does the 8,000km oil change.

Pics below show the findings. Sorry that focus on some metal flakes is not great; only my second stringer camera available today.
