I changed this oil and filter after this sample was taken. I know several of you are not happy with the short interval for this type of oil. But for the current interval, I am taking it out to 10,000 miles to see how it goes. I am using Mobil 1 M1-209 filters.
The silicon is from sealers, so the fact that it is still high doesn't concern me. The copper is from the engine oil cooler, so I am not worried about that as well. The level of Iron, although clearly far from a problematic level, was a slight surprise, I somewhat expected it to be lower. So I think break in was still completing during this run. Having said that, on a ppm/mile basis, iron did go down a bit.
Anyone think I should do a UOA without changing the oil prior to the 10K mark on this interval?
