Here's the UOA on my 2003 Chevy 3500 that I purchased in June.
4 years, 3479 miles on oil, 32,900 miles on truck.
Iron 9
Chromium 0
Nickel 0
Aluminum 1
Copper 12
Lead 19
Tin 1
Cadmium 0
Silver 0
Vanadium 0
Silicon 13
Sodium 2
Potassium 1
Titanium 0
Molybdenum 0
Antimony 0
Manganese 0
Lithium 0
Boron 1
Magnesium 15
Calcium 3976
Barium 0
Phosphorus 1139
Zinc 1240
Fuel Water 0.00
Soot Vis 100C cSt 13.50
Here's the back story: I bought the truck and a slide in camper from a widow who had kept the truck after her husband died. In 4 years she put less than 1,000 miles on the truck. Everything looks like new. They were AmsOil fans.
The truck is now on Kendall Super D-XA 15W-40. I've been a Kendall user for more than 25 years and faithfully use their UOA on everything that contains lube.
The only things that stood out are lead and calcium. Huge Ca seems to be an AmsOil additive. I'll watch Pb. Planned drain, 1 yr. or 6,000 miles.
Any comments?
