Got my second UOA report back today.
First UOA run was this one in May '08, after having some mechanical problems and running an extended OCI:

As you can see, not great results. As that post says, I changed that oil for Petro-Canada 'Maximum' 5W-30, which I ended up running 8096 miles, and NOT analyzing. In Nov. '08, I changed it out for this oil.
During both the PC run and this one, I used no additives in the gas or oil. I also added no top-up oil.
2002 Chevrolet Cavalier, 2.2 OHV
123,827 miles on unit (198123 km)
Motomaster Formula 1 dino 5W-30
Motomaster Formula 1 oil filter (Fram TG clone)
4.4 litre initial fill, no top-up oil, 0.8 liter consumption
8018 miles on oil (12,830 km)
Iron 20
Chrome 1
Moly 47
Alum. 3
Copper 3
Lead 8
Tin 1
Titanium 0
Nickle 0
Silver 0
Silicon 15
Sodium 17
Potassium 2
Zinc 656
Magnesium 15
Phos. 653
Barium 0
Soot 0
Sulf. 32
Oxid. 24
Nitrat. 16
100C visc - 9.01
TBN - 1.5
Anti-freeze, fuel, water all 0
Lab comments just said that nitration was high, and may be due to running interval too long.
My thoughts? I'm thrilled with these results, lot better than I thought they would be. This run was during the 'Ottawa bus strike' during the winter, so LOTS of idling and low-speed operation in freezing cold weather. Looks like I ran this oil just to the right point!
All comments are welcome!
