Here is the last filter w about 1400 miles on it from the C1500 and a total run of 5656 mile oci on the oil and EC30. Filter is dark but no real bits of anything, have a comparison pic w my Expedition with it's first filter change which was a ST2 included. Truck has developed a rear driver side valve cover gasket leak since running the EC30. And the PCV grommet on passenger side and breather grommet on driver side are leaking oil around them as well since running the HPL EC30. Will have fixed once I get the truck back from my son.
New oil and filter was a new PH5 filter and oil was QSFS Euro 5w40
