You're unlikely to find any MPG value for lawn mowers, as they aren't intended for travelling. You might find a GPH, gallons per hour, though. Or possibly a gallons per acre or something like that.
Lawn mower gas mileage is generally categorized by gallons-used-per-hour, and the larger the motor's horsepower, the more fuel is used. A riding mower, for instance, with a 12 h.p. motor, and a one-gallon-tank, in middle-gear, will get around two hours per gallon.
It looks like the 2011 Toyota RAV4 2WD gets the best MPG. It gets 28 MPG on the freeway and 22 MPG in the city. There is no reason it wouldn't be available in Honolulu.
