UOA by Oil Analyzers: LAB COMMENTS: Data flagged for observation only; Copper is at a MODERATE LEVEL; Suspect most of the copper may be coming from the lube cooler (as applicable); Potassium is at a MINOR LEVEL; Potassium sources: coolant (antifreeze), lube additive or supplement, solder flux, coating on new bearings, rust preventive coating, or environmental. Your note was taken into consideration; Oil is suitable for continued use. Re-sample in 7,000 miles or 125 hours.
Overall severity of report--------2 (abnormal)
