Recommendation/Comments: ACTION REQUIRED ‐ ELEVATED WEAR METALS LEVELS. Determine cause of elevated wear metals levels and take corrective action. If the wear metals levels are elevated for the first
time with no history of an increasing trend, then resample immediately to confirm condition. Because silicon levels are not also elevated, abrasive dirt is not the cause of this condition. Possible causes of elevated
wear metals include: a. Worn of oil‐wetted parts; b. Contamination from previous fill; c. Over‐extended oil service life; d. Normal break‐in of new equipment. Continue to closely monitor the equipment and oil for
signs of further condition regressions. Contact your ExxonMobil representative for further assistance if necessary.ACTION REQUIRED ‐ ELEVATED COPPER LEVEL. Determine source of Copper ﴾Cu﴿ and take corrective
action. If the copper level is elevated for the first time with no history of an increasing trend, then resample immediately to confirm condition. Possible sources of copper include: a. Wear of pump parts; b. Metal
pick‐up from plumbing lines; c. Oil coolers and fittings. The oil may be unfit for continued use and should be monitored closely for further condition regressions. Contact your ExxonMobil representative for
further assistance if necessary.
