At 150000 miles test relults were:
Iron 53
Cr 1
Pb 17
Cu 4
Tin 0
Al 9
Nickel 0
Silver 0
Boron 19
Na 66
Potassium 76
Magnesium 24
Calcium 2195
Phosphorous 1090
Zinc 1210
Molybdenum 114
Fuel and glycol Neg, water
Visc@100C cST 11.6
Soot Oxidation 23.00
Nitration 11.40
Lab reports wear levels to be normal, and the slightly high level of sodium could be a slight or intermittent Glycol leak. Antifreeze test was negative.
This car is a daily driver in tough conditions and has had an AutoRx treatment @135k. It needs a TPS and other than that runs like a top.
Change or keep the oil type and OCI?
Thanks for your thoughts.
