Motor spun a bearing 2 days after the sample was taken. New engine from Jasper has been ordered. I'm told the oil filter was full of metal shavings (brother-in-laws truck).

Oil Analysis Comments:
Infrared results indicate Oxidation is significantly high; Cylinder region metals (pistons, rings, liners etc) are at a moderate level. Silicon is at a moderate level. Silicon sources can be abrasives (dirt, Alumina Silica), seals and gasket material, lube additive or lube supplement, and/or environmental contaminant. Replace oil filter and top off system with fresh make-up oil if not done when oil sample was taken. Re-sample in 3,500 miles or 65 hours.
