2019 GT PP1 - details on this change; After the drama I felt over the 10 quart specification leaving the car about a half quart from 'maximum' on the dipstick and adding it back up with a full quart when it hit 'minimum' and the 2k rattle ordeal that seemed to be mitigated by having it at 'maximum. My car having typewriter tick, piston slap, whatever it is.... that has come and gone over the last 6 months, but has been present since day 1 more or less. I decided to do an early oil change on my Motorcraft Synthetic Blend 5/20 to get it analyzed and just as a general precaution considering the issues.
They claim that my report looks good, but I notice that my copper level is about twice 'normal.' Do the PP1 cars have an oil cooler that might account for some of that? I'm embarrassed that I don't even know. I know it has a beefier radiator. I'm guessing that their 'average' of 5,800 miles means that if I am like 69% of average with 4k that I should multiply my results by 1.31 to get an accurate measure against their averages?
I haven't become an expert on all of the theories of what is happening with the Coyote 3 motors, but I seem to recall one theory that stood out was something to do with the crank maybe? I know almost nothing about the internals of an engine, but would that also raise concern for the crank bearings (or main bearings?) possibly accounting for excessive copper?
I'm not trying to create any hysteria, but I thought maybe some here with more intimate knowledge of these cars specifically could shed some light?
I get it that the copper is soft and doesn't cause harm itself and the iron is the one to watch for being an indication of internal wear compounding itself with the oil I guess. Just curious about that copper level.
Thanks!
