oil analysis @ 6844 miles
Changed the oil today and had them do an oil analysis to see if I've gone too far on my oil change. Here are the results:
aluminum 6
chromium <2
copper 5
iron 17
lead <2
tin 5
silicon 8
potassium <2
sodium <2
moly 65
water <2
oxidation <2
visc@100 14.8
glycol ND
fuel <2
TBN 8.2
nitration 2.4
soot 1.9
From all I can read about UOA, these number look good. It was with Chevron Delo 15w40, AFE oiled drop in air filter, oil fiter was Baldwin, I think. Local big rig oil change business has done almost all my oil changes and has the sample analysis machine there at their location. Any comments?
