This is an analysis of the factory fill at 2800 miles after a hard break-in. The oil was never topped off.

Element Actual PPM / Typical PPM

Aluminum 1/2
Chromium 1/1
Iron 29/7
Copper 154/5
Lead 1/5
Tin 2/1
Molybdenum 828/53
Nickel 1/0
Manganese 20/4
Silver 0/0
Titanium 0/0
Potassium 4/1
Boron 138/44
Silicon 330/10
Sodium 8/15
Calcium 1929/2187
Magnesium 12/266
Phosphorus 850/771
Zinc 792/937
Barium 6/0

Flashpoint 410F
Fuel <0.5%
Antifreeze 0
Water 0
Insolubles 0.2%

SUS Viscosity @ 210F: 48.8
cSt Viscosity @ 100C: 6.89

Comments: High wear and silicon are common finds in new engines such as yours. The excess wear is due to new parts wearing in, while silicon is from sand-casted parts and sealers used when assembling your engine. With a few more oil changes, everything should read around if not better than, universal average levels. Those averages are based on an oil run of around 4200 miles. The viscosity was in the 5W20 range with no fuel or coolant present. No abnormal finds.
