Here is a log of 3 UOA with both PP 5w-20 and 0w-20.
The second column should read around 6,391 miles not the misprinted 4,391.
Background of this vehicle.
Primarily used around town for short trips. Typical day is drive to the gym 2 miles away. Drive 2 miles back to home. Drive 3.5 miles to work. Drive 3.5 miles home. With that being said on the weekends I drive typically 50+ miles and the oil gets up to operating temperature. There are some highway trips on this change. I would say 35% highway miles and 65% city. Oil filter for the two most recent changes was M1 and prior to that was Motorcraft FL820s or Mopar cant recall. There is a factory oil cooler hence the trending down level of copper.
Notes about this oil change. This was run during the Dallas TX winter right up to the beginning of our summer. I was a little quick on the draw for collecting this sample. I let maybe a quart or 2 tops out before collecting. Its a 7 quart system.
Hoping you guys can shed some light on this most recent change. I'm a little disappointed in the elevated levels of Iron. I don't think its anything to be worried about but was wishing to see an overall better UOA with the 0w-20 vs 5w-20 with the talk I've seen of better base stocks used in the 0w vs 5w. Not sure what's up with the Chromium all of sudden showing up. Is this from piston ring wear or could this be present in a VOA of PP 0w-20? Anything else I should be concerned about? I was able to snag up 3 jugs of PP 0w-20 on clearance at Walmart for 13$ each and would like to use it instead of going back to 5w-20.
Learned a lot lurking around here so excited to see your guys comments.
