I have an '05 Ram 1500 5.7 Hemi. I'm running Mobil 1 5w20t or 5-30wt when 5-20 isn't available w/Napa Gold filter I'm seeing high Cu ppm. UOA My question is whether a brand change of oil be beneficial to curb the high wear? Recommendations?
Thanks!
from the 2 reports it looks like hemi's throw copper high what is in the motor that is brass or copper? most likley normal. iron is low so is aluminium I would not worry.

I got one too. But I use 5W-20 cheveron or pennzoil in mine. For a 5K OCI I cant bear to use a syn. I think that the HEMI spits copper due to it being a pushrod engine. But it sure is a tough motor.
