Mobil 1 0w40 - 5100 miles / 100 hours - Modified TDI
This sample period was December through May. Lots of 10 mile trips in 0F to 30F temps, going right from the parking spot to 70 MPH or 80 MPH Interstate driving, merging with gusto.
How did I end up with MORE additives than the virgin sample? (below) (FWIW the UOA additive levels are more in line with what Mobil says this oil has)
