Driving and Car Maintenance: Transportation accounts for 66% of U.S.
oil use -mainly in the form of gasoline. Luckily, there are plenty of
ways to improve gas mileage.

Driving Tips:- 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
winter days is needed. Anything more simply wastes fuel and increases
emissions.- Aggressive driving (speeding, rapid acceleration, and
braking) wastes gas. It can lower your highway gas mileage 33% and
city mileage 5%. Drive at lowest and constant rpms; 2000 rpm are
enough; you can save up to 30%. Even a Porsche can be driven at the
4th gear at 20 mph and at the 6th gear at 50 mph with 2.5 times less
fuel consumption.- Avoid high speeds. Driving 75 mph, rather than 65
mph, could cut your fuel economy by 15%.- When you use overdrive
gearing, your cars engine speed goes down. This saves gas and reduces
wear.- Use air conditioning only when necessary.- Clear out your car;
extra weight decreases gas mileage. Each 60 pounds increases fuel
consumption by 10%. - 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%.- Check into carpooling and public transit to cut mileage and car
maintenance costs.

Car Maintenance Tips:- Use the grade of motor oil recommended by your
cars manufacturer. Using a different motor oil can lower your
mileage by 1% to 2%.- Keep tires properly inflated and aligned to
improve your gasoline mileage by around 3.3%.- Get regular engine
tune-ups and car maintenance checks to avoid fuel economy problems due
worn spark plugs, dragging brakes, low transmission fluid, or
transmission problems.- Replace clogged air filters to improve gas
mileage by as much as 10% and protect your engine.- 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
the engine is warm. Do not forget that in the first mile your car
8 times more fuel, in the second mile 4 times and only after the
fourth mile it becomes normal.Long-Term Savings Tip- Consider buying
highly fuel-efficient vehicle. A fuelefficient 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
