Ok this is my 2nd UOA in a week but 1st for this truck!
2003 Silverado 5.3 V8
6,831 miles on the engine
3,000 miles on the oil
1st full run with Mobil1 5w30
Started with Mobil 1 oil filter but after I found out it did not flow well I put on a Napa Gold 1522 and toped off oil with 3/4 qt.
Aluminum 4
Chromium 1
Iorn 25
Copper 168
Lead 3
Tin 1
Molybednum 81
Nickel 1
Manganese 2
Silver 0
Titanium 0
Potassium 0
Boron 171
Silicon 27
Sodium 9
Calcium 2747
Magnesium 21
Phosphorus 803
Zinc 924
Barium 0
TBN 4.3
SUS Viscosity @210 F 60.5
Flashpoint 420
Fule 0.5
Antifreeze 0
Water 0
Insolubles 0.5
I don't know much but Iorn and Copper seem very high! Should I be worried about this? I'll wait to see what Terry tells me but I don't like this report, my Camaro LS1 was better in my eyes but like I said I don't know much.
I should mention that 3 days a week I drive less than 6 miles to work and less then 6 miles back home mostly at speeds above 50 mph.
