if you do a lot of short stop and go city drivng and then do a hiway trip of 50 miles or more at hiway speeds does that "burn off" or heat up and evaporate the fuel contamination in the oil. i assume that the fuel is not fully cooked off though, am i right?
also if you were on an exptended drain interval with syn and a big oil capacity (8qt) and wanted to "freshen the oil" by either changing the filter OR replacing the oil, which would be better?
i am planning a UOA at 5k on my '04 MB CLK first but want to plan ahead in case the fuel contamination is on the high side.
