It depends on your "efficiency" definition, David. While they lose a very
small amount of fuel efficiency due to the effectiveness of ejecting the
exhaust gasses completely and some energy to run the blower, they are nearly
twice as efficient for size since each cylinder puts out twice the energy of
a 4 stroke.

Many manufacturers of synthetic oil DO claim it is more slippery and that it
will improve mpg.
