Time in service: 12 months
Miles in service: 11,240
Driving conditions: mix of very short commutes (3-miles one way) with 200-mile hwy trips every couple of weeks.
Oil: Mobil1 0w-40 API SN
Oil filter: Mann (OEM)
Air filter: Mann (OEM)
Make-up oil: none
Sampling technique: Blackstone pump via dipstick tube.
I must say, the TBN retention in this new SN stuff is impressive, as is shear stability.
The previous sample on the above report (10/16/11) was on M1 0w-40 SM, 8800 miles and 1 year as well. That sample had multiple 12-mile commutes, but no extended hwy trips.
