This test came immediately after a 250 mile return trip home and was conducted to determine if the previously existing fuel dilution to the oil would be mitigated by evaporation resulting from extended use at operating temperatures. The answer is yes, to some degree. Fuel dilution came down to what the lab called "normal," but obviously not far from returning to "abnormal." My estimate is that after one week of typical use (cold start then 10 mi to work, cold start then 10 miles to the gym then 2 miles home on Mon. thru Wed., with Thur & Fri. being cold start then 2 miles to gym, 2 miles home, 10 miles to work, cold start then 10 miles home) the dilution number will be back up. (I say that because the first test I posted consisted of that same typical weekday driving which immediately followed a 400 mile day trip.)
While I will still hold out hope that after a proper wear-in things will change, it is a very slim hope indeed.
