I drive five miles each way weekdays and made a trip to SC (100F temps) and MD (upper 90’s). This summer was one of the hottest on record in NJ so this oil saw a lot of days in the 90’s. I also drive on the beach. No engine mods.
I swapped out my Amsoil air filter for an OEM one and I’m a little surprised that silicon didn’t drop. Maybe it’s still breaking in? Dirty Fumoto?Copper went up a little as well.
I changed the oil after the UOA at 7,500 miles and maybe I’ll go to 7,000 on the next one. Or maybe I’ll just save my money and not bother with UOA’s because I trust the elves, regardless of vintage.
First column is current, second column is Green GC with 5,930 and third is M1 5W30 w/5,774.

Dennis: The small amount of gas was still there in this third sample so it may be an operational hazard you will have to live with. It has not hurt the oil’s viscosity any and we don’t see any harm being done to wear. Unless the fuel amount in the oil gets much above 2.0%, we doubt we will see any harm from its presence. Copper made a little unexpected uptick in this sample and we have no idea why. It comes from bronze parts. It should read at about 5-ppm in this sample. We will watch it for you next time, but we would bet it will drop. The TBN was 3.6 okay.
