This car has seen 7-10k oil change intervals with 5W-20 synthetic (mostly Mobil 1) since the 30K mile mark. I have done most of the oil services on this car. When this oil was installed at 143K, a valve clearance adjustment and a spark plug replacement were also performed.
Also, this oil fill was Mobil 1 High Mileage 5W-20, not regular Mobil 1. The Oil Life Monitor was at 40%. This car sees mostly highway stop-and-go driving and the fill was in service for about 5 months. The air filter was a Wix that has been in service for 20K. Oil Filter was Genuine Honda.
I think the Fuel Dilution is due to the oil sample being taken when the engine was not fully warmed up. The car was here for a starter replacement and I only ran the car for about 5-10 minutes before taking the oil sample.
