Here's an analysis of a 2,554 mile run of PYB 5w30 along with a quart of Kreen @ 16oz doses roughly 1,000 miles apart.
I only did this UOA to check and make sure that the Kreen and previous runs with Auto-RX weren't hurting the engine wear wise. Of course long term engine health will be something that the next owner will have to deal with as I plan to sell the car @ 300k.
All previous runs were of Amsoil OE 5w30.
