Hi all, thought I would share some results from recent oil analysis at blackstone. I recently switched from M1 0W40 to 5W40. I did not think that the colorado climate really required the 0W40 and I was hoping that the 5W40 would somewhat slow the super slight cold leak leaving the oil pan overnight. Considering that the turbo is oil cooled and oil lubed and considering that the vehicle is regularly raced up and down mountain passes both on and off road, I thought these results were amazing. I am also especially excited that there is no coolant and no gasoline in the oil. Lastly, I'm very happy with the super service at blackstone labs and would readily recommend them to anyone as another terrific diagnostic tool. Any thoughts????
Narrative: No problems showed up here. Comparing wear in this sample to the universal average for this type of engine, you can see you have generated virtually no wear into the oil after 3,000 miles oil use. Those average are based on a 4,800 mile oil use interval. The TBN was still strong at 8.0, so this oil still has plenty of active additive left. 1.0 is a low reading. No fuel dilution or anti-freeze was present and the viscosity was normal for a 5W/40. The low insolubles show good oil filtration. At 141,065 total miles, we think this engine is doing very well.

SUS Viscosity At 210 F: Should Be 65 -78, Was 71.7
Flashpoint in F: Should Be >375, Was 390
Fuel %: Should Be <2.0%, Was <.5%
Antifreeze%: Should Be 0, Was 0
Water%: Should Be <.1, Was 0
Insolubles%: Should Be <.6, Was .4
Personal Note: Not sure why the magnesium measured so high? Or why the phosphorus and zinc showed somewhat high? Any thoughts on that???
Thanks,
