Performance Analysis
No change in performance since the last check up.

Oil Analysis
With 6,742 miles on this oil drain, we see signs of increased oxidation levels and viscosity increase. It appears that as the engine continues to increase in mileage, the oil is under more stress during the drain. (Some of this may be due to the excessively hot weather we had during this drain.)
