Do these five simple things to save gas and money as you develop and greener lifestyle.1: Drive the vehicle with the best gas mileage.Do you own more than one car? When possible, drive the vehicle that gets the best gas mileage to save gas and get the most out of what you spend on transportation fuel.2: Empty your trunk and lighten your loadFor every-day errands, like visiting the grocery store, back-to-school shopping, and trips to the home improvement store, it is convenient to put your purchases in the trunk. But don’t leave stuff in the trunk while you drive to carry out other errands. For every 100 extra pounds in your car, you reduce your gas mileage by as much as 2 percent.Simply unloading the trunk can save you $0.07 per gallon of gas, or $40-50 each year. Or perhaps you are driving a car with a roof rack? Putting cargo on top of your car can be a huge help when taking gear on a vacation. But remember that leaving anything on top of you car will create wind resistance and decrease your gas mileage.3: Keep your tires inflatedPresident Obama took some criticism when he suggested this as an energy saving measure, but he had a point. You should keep all tires inflated to the maximum recommended limit. Check manufacturer’s specifications for maximum tire pressures.This will reduce rolling resistance and save you on gas. Radial tires are the recognized fuel-savers and some newer models are available that promise better fuel economy. The expected improvement ingas mileage form this simple step is about 3%, leading to savings of about $0.11 a gallon. For an average driver, this is worth about $55 to $75 per year.4: Drive steadilyEliminate jack-rabbit starts. Instead, accelerate slowly and smoothly when starting from dead stop. Every time you slow down or speed up unnecessarily it 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 unexpectedly.(The potential drafting effect is just not worth it.) In addition, think ahead when approaching hills. If you accelerate, do it before you reach the hill, not while you’re on it.5: Drive less. It seems obvious, but many people don’t give jumping in the car to go somewhere on a notion a second thought. A great way to save gas and lessen the wear and tear on your vehicle is to combine errands into the fewest number of trips.Turn several shorter trips into one longer, multipurpose trip covering the same distance. You can save time by cutting the overall miles driven, and reduce wear on your car by traveling while your car is warmed-up and operating more efficiently.Bonus tip: Although it may not feel that way, winter is on the way as I write this. During cold weather watch for icicles frozen to car frame. Up to 100 lbs. can be quickly accumulated! Snow and ice left on your car can also cause tremendous wind resistance. Scrape it off before getting on the road this winter.
