Blackstone Comments:
Aluminum is nearly twice the average amount after this 5,100-mile oil run and shows more wear at the pistons. The good news is that lead came down and is closer to average now, so we're less worried about the bearings. The viscosity was thin for 15W/40, but it wasn't caused by any harmful contamination like fuel, coolant, or water. Insolubles were low at 0.4%. The TBN read 2.6 and anything less than 1.0 is low. The lab noted some soot, which might show some combustion issues. Try another ~5,000 mile oil run for an apples-to-apples comparison.
