Anybody?

Pulled the OilGuard today, and dropped the old oil and filter. Went with Delvac again, ESP this time, and an Amsoil full-flow.

Will check again in 2500 miles, and I sure hope copper is close to normal again.

Anybody have any other ideas?

That sounds like a plan. See if that reduces the copper. Systematic approaches work the best.

Thanks. Fingers crossed here!

Steve,

Been chasing the copper monster for almost 2 years on the DMax that was linked in this thread. It's still coming down, lab suspects copper core leaching from the oil cooler since there are no other wear metal increases.

Silicon is a measure of dirt/dust getting past the air intake system. 20 ppm is considered normal. Air intake systems that can keep it below 10 ppm at 5,000 miles are considered doing an excellent job in a turbo diesel.

Here's is the back side of a Schaeffer's report explaining the levels found on a UOA report.

Hope this info helps, I bet your truck is fine.

Just got another UOA on the customer's DMAX I referenced above. Still chasing the copper monster here as well. Been fine pulling his 31' 5th wheel the past 2 years - seems to be copper core leaching.

I thought the copper column was an additive for a second, that's an insane amount of copper!!!
