Small engine efficiency Thu, Nov 19, 2009
I own three machines that utilize small gasoline engines:  A push lawnmower, a weed whacker, and a leaf blower.  During the summer, I use all three every few weeks to keep my tiny yard looking nice.  In the fall, I use the leaf blower pretty extensively to clear leaves.  Despite that incessant hum of engine noise and the wonderful smell of exhaust, I would posit that these engines are actually pretty efficient, more so than a typical car.  This isn't a scientific statement or one that I can prove with numbers, but all I can say is that only after three years of home ownership did I need to refill my five-gallon gas container that feeds all three devices.  I burn through five gallons of gas with my car in probably two or three days. #technology
