As U.S. gasoline prices hit records on almost a daily basis, an increasing number of motorists are following a radical driving technique designed to eke out every last mile from a tank of fuel.
Known as “hypermiling,” the method can double gas mileage, even in gas-guzzling vehicles that would normally get less than 20 mpg.
Promoted on a growing number of Web sites, hypermiling includes pumping up tires to the maximum rating on their sidewalls, which may be higher than levels recommended in car manuals; using engine oil of a low viscosity, and the controversial practice of drafting behind other vehicles on the highway to reduce aerodynamic drag.
Is it worth risking to crash your car to save $50/month on gas? You tell me!
