The results are in:
Car: Cadillac Cts
Year: 2005
Engine type: LY7 3.6L V6 VVT Non-DI
Sump capacity: 5.7 liters (6 qts)
Oil Filter: OEM
Miles on unit: 102163 miles
Miles on oil sample: 10144 miles
Oil life monitor: 1% engine oil life
Added oil: 2 qts
Driving condition: extreme cold weather startup, a lot of idling and 50-50 highway-city driving.
First row is the last analysis with still mobil 1 5w30 with 10k miles on the oil change. the next one, is the new one with 10144 miles.

Soot: 0% / 0%
Water: cSt at 40 deg C: 52.81 / 56.53
cSt at 100 deg C: 9.41 / 9.73
TBN: 5.18 / 4.84
dilution (volatile): 0% / 0%
btw, I received an email saying that the lab took the wrong sample for my virgin oil analysis and they will send me the new VOA at the beginning of next week + 2 free UOA.
Feel free to comment!
I think the OLM is doing its job and I think the car is in good shape + the oil, regular Mobil 1 5w30 synthetic gmspec 4718m is doing fine versus whatever we hear here and there.
The 2 qts of make-up oil is possibly due to a small timing chain cover gasket that is seeping a little. There is improvment from last sample. I dont think the previous owner did put synthetic in the engine...
