ok this isnt my car but i take care of it so i wondered a while ago if i was doing the right thing in regards to oci. after the first oil change i was using m1 5w20 with 10K intervals, at some point switching to m1ep. well i guess i was doing ok all this time.
BONUS!!1! i wondered where the insolubles came from, then i remembered about a month before i did the oil change i used a can of seafoam to clean the intake and throttle body. well thats my best guess anyway.
POSSIBLE FUTURE BONUS!!!1!! up until now the car had the stock oil filter, the motorcraft fl-2017-b cartridge type. the day i changed the oil i installed a filter housing from an older 2.3 i got tired of that mess every time, now im running the fl-910. hopefully i can get a few more oci's out of this car before it gets traded, i really wanna see if anything changes. i read on here, i think, that the cartridge filters were good to 40 micron and the canisters were good to 20 micron. unless i dreamed it.
