Avoid warming up of engine, even on cold mornings – 30 seconds is plenty of time. Don’t start and stop engine needlessly. Idling your engine for one minute consumes the gas amount equivalent to when you start the engine. Avoid “REVING” your engine, especially just before you switch the engine off; this wastes fuel and washes oil down from the inside cylinder walls, owing to loss of oil pressure. Accelerate slowly when starting from dead stop. Don’t push pedal down more than 1/4 of the total foot travel.
Buy gasoline early mornings or late evening is best. During these times gasoline is densest. Choose the type and brand of gasoline carefully. Certain brands provide you with greater economy because of better quality. Avoid filling gas tank to top. Overfilling results in sloshing over and out of tank. Never fill gas tank past the first “click” of fuel nozzle, if nozzle is automatic.
Exceeding 40 mph forces your car to overcome wind resistance. Never exceed legal speed limit. Primarily they are set for your traveling safety, however better gas efficiency also occurs. Traveling at 50 mph give you up to 20% better mileage when compared to former legal speed limits of 65 mph and 70 mph. Traveling at fast rates in low gears can consume up to 50% more fuel than is needed. Manual shift driven cars allow you to change to highest gear as soon as possible, thereby letting you save gas if you “nurse it along”. Keep windows closed when traveling at highway speeds. Open windows cause air drag, reducing your mileage by 10%. Drive steadily. Slowing down or speeding up wastes fuel. Also avoid tailgating – the driver in front of you is unpredictable. Not only is it unsafe, but if affects your economy, if he slows down unexpected.when dealing with hills, If you accelerate, do it before you reach the hill, not while you’re on it.
Do not rest left foot on floor board pedals while driving. The slightest pressure puts “mechanical drag” on components, wearing them down prematurely. This “dragging” also demands additional fuel usage. Avoid rough roads whenever possible, because dirt or gravel rob you of up to 45% of your gas mileage. Use different roads when safer, shorter, straighter. Compare traveling distance differences – remember that corners, curves and lane jumping requires extra gas. The shortest distance between two points is always straight. Stoplights are usually timed for your motoring advantage. By traveling steadily at the legal speed limit you boost your chances of having the “green light” all the way. Place gear into neutral position. This reduces transmission strain and allows transmission to cool. Park car so that you can later begin to travel in forward gear; avoid reverse gear maneuvers to save gas. Regular tune-ups ensure best economy; check owner’s manual for recommended maintenance intervals. Special attention should be given to maintaining clean air filters… diminished air flow increases gas waste. Inspect suspension and chassis parts for occasional misalignment. Bent wheels, axles, bad shocks, broken springs, etc. create engine drag and are unsafe at high traveling speeds. Remove snow tires during good weather seasons; traveling on deep tire tread really kills the fuel.
Inflate all tires to maximum limit. Each tire should be periodically spun, balanced and checked for out-of-round. When shopping for new tires, get large diameter tires for rear wheels. Radial designs are the recognized fuel-savers; check manufacturer’s specifications for maximum tire pressures. Remove vinyl tops – they cause air drag. Rough surfaces disturb otherwise smooth air flow around a car’s body. Bear in mind when buying new cars that a fancy sun roof helps disturb smooth air flow (and mileage). Auto air conditioners can reduce fuel economy by 10% to 20%. Heater fan, power windows and seats increase engine load; the more load on your engine, the less miles per gallon. Remove excess weight from trunk or inside of car – extra tires, back seats, unnecessary heavy parts. Extra weight reduces mileage, especially when driving up inclines. Car pools reduce travel monotony and gas expense – all riders chip in to help you buy. Conversation helps to keep the driver alert. Pooling also reduces traffic congestion, gives the driver easier maneuverability and greater “steady speed” economy. For best results, distribute passenger weight evenly throughout car. During cold weather watch for icicles frozen to car frame. Up to 100 lbs. can be quickly accumulated! Unremoved snow and ice cause tremendous wind resistance. Warm water thrown on (or hosed on) will eliminate it fast.
