Travel:

• Drive sensibly. Aggressive driving (speeding, rapid acceleration and braking) wastes gasoline.
• Consider buying a highly fuel-efficient vehicle. A fuel-efficient vehicle, a hybrid vehicle, or an alternative fuel vehicle could save you a lot at the gas pump and help the environment. See the Fuel Economy Guide for more on buying a new fuel-efficient car or truck. 
• Combine errands into one trip. Several short trips, each one taken from a cold start, can use twice as much fuel as one trip covering the same distance when the engine is warm. 
• Replace clogged air filters to improve gas mileage by as much as 10% and protect your engine. 
• Get regular engine tune-ups and car maintenance checks to avoid fuel economy problems due to worn spark plugs, dragging brakes, low transmission fluid, or transmission problems. 
• Keep tires properly inflated and aligned to improve your gasoline mileage by around 3.3%. 
• Use the grade of motor oil recommended by your car's manufacturer. Using a different motor oil can lower your gasoline mileage by 1%-2%. 
• Check into telecommuting, carpooling and public transit to cut mileage and car maintenance costs. 
• Reduce drag by placing items inside the car or trunk rather than on roof racks. A roof rack or carrier provides additional cargo space and may allow you to buy a smaller car. However, a loaded roof rack can decrease your fuel economy by 5%. 
• Clear out your car; extra weight decreases gas mileage. 
• Use air conditioning only when necessary. 
• Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas. 
• When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces wear. 
• Avoid high speeds. Above 60 mph, gas mileage drops rapidly. The http://fueleconomy.gov/ Web site shows how driving speed affects gas mileage. 
• Aggressive driving (speeding, rapid acceleration, and hard braking) wastes gas. It can lower your highway gas mileage 33% and city mileage 5%. 
• Idling gets you 0 miles per gallon. The best way to warm up a vehicle is to drive it. No more than 30 seconds of idling on winter days is needed. Anything more simply wastes fuel and increases emissions.
