| Once it was considered good to keep the
car engine idle a minute or two following cold stars. Today, with modern
technology, the opposite is true. An engine operating under road conditions will
warm up faster and run more efficiently than one that is idling. Idling just
burns gas (on average, about a gallon an hour). When you have a full tank of gas, park the car facing downhill is possible: this will prevent any gas from coming out of the tank. Parking in areas of less or no sunlight helps prevent the gas from steaming that would occur if you parked in the hot sun. Your car will stay cooler, too, and that means less gas consuming work for the air conditioner once the engine is started. Stay away from wide-track tires if you want top mileage (耗油1升行驶的英里里程). Narrow-track tires produce less friction and thus rolling resistance.
