The car owners at NASCAR completely disassemble, clean, and overhaul their engines after every race. They even have engines for qualifying and another engine just for race day, all of which are overhauled after every race. The car owners at NASCAR do not care because the fuel is only in the engine for a few days.

The average consumer cannot overhaul their gasoline powered equipment on such a schedule. The man hours to remove and replace the power plant in a modern automobile approaches a full day's labor.

Ethanol injected as a knock suppressant into a high compression engine may yield benefits. lumberjack_jeff Jul 2015 #20

the high compression is achieved by use of turbo-charging not fixed by stroke. Bill USA Jul 2015 #21
