Here's the latest report after a thorough A-RX clean. This is the first oil change after the A-RX rinse.
This vehicle has also been using Redline 85 Plus at a maintenence dose rate in the fuel. It has made a huge difference to the overall performance, although I suspect this may be where the elevated lead count is comming from, although the other wear metals have dropped. The only other thought it is residual cleaning from the A-RX and the esters in the D1

Any comments ?
