I just received my UOA via e-mail that I mailed on 11/22 (and I thought the USPS had lost)....I was alarmed that the copper is so elevated.
The left column is from a 7750 mile run on older SH Pennzoil Performax done in Aug 2015 with 60K on the car. The right column is at the current 86K and a 6875 mile run on older SJ Proline 5w30 dino (which Hyundai allows according to the OM).
I had put this SJ rated oil in at the end of August when my daughter was heading back to school assuming she would only put about 3K by Thanksgiving but...NO...she put almost 7K (sports and nursing clinicals I guess)....that's why I had a UOA done. I only put the readings which changed...if there is nothing listed it's the same as the left column.
I had the timing belt, water pump and serpentine belts changed right before the August oil change.
What are your thoughts on the big jump in COPPER? I don't believe there is an oil cooler on the Hyundai Beta engine which would leech copper...
Thanks
