A bit disappointed with the analysis, particularly relating to fuel dilution. At 3.1% it means there is almost 6 ounces of gas in the oil. At 8.6 cSt, the oil is now at SAE 20 viscosity after ~1,300 miles. Of course MB 229.5 spec calls for 0/5W-30 or 0/5W-40. Hopefully the fuel got there during the dealership concierge's explanation of the features and functions during delivery in which the car idled for 20 to 30 minutes with only 50 miles on the odometer. And hopefully it will get better after wear-in and under normal operating conditions.
