Here are some good gas savings tips collected from various sources (listed where known):

Add 3-5 pounds OVER the manufacturer’s recommended inflation pressure to your tires, for less rolling resistance. (Not recommended in winter, slippery, icy or wet conditions) — jmooneyham.com

Avoid ‘topping off’ your tank. Chances are that even if you manage to prevent some gas running onto the ground you’ll still lose some due to expansion once it warms up in the tank. — jmooneyham.com

Avoid driving on dry pavement with front axles engaged on four wheel drive vehicles. It causes needless, wasteful friction. — jmooneyham.com

Buy the lowest octane gas your car will run on without problems. — jmooneyham.com

Call ahead first. You can save gas, wear and tear on your car, and money too by comparing prices, checking delivery times, opening and closing schedules, etc., via phone before ever going anywhere. — jmooneyham.com

Clean off all ice and snow in winter

Don’t tailgate. It necessitates constant braking and acceleration moves. — jmooneyham.com

Don’t fly flags on your car – they add drag. — funandsafedriving.com

Fill your tank at the coolest time of day. Fuel is denser when it’s cool in the early morning or late night.. Your engine consumes fuel by weight but gas pumps dispense fuel by volume. The colder the fuel is when you pump it, the more of it you get for the same money. — funandsafedriving.com

Get a credit card with 5% rebates on gas, use it for all your fuel purchases and guarantee yourself an automatic 5% savings. — funandsafedriving.com

Keep your tires properly inflated

Never ‘rev up’ your engine before shutting it off. It accomplishes nothing anyway. — jmooneyham.com

Park your car in the shade to reduce gas evaporation. — jmooneyham.com

Remove bicycle or ski racks in between trips. — funandsafedriving.com

Remove unnecessary stuff from your car
