DRIVING AND CAR MAINTENANCE
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 on winter days is needed anything more simply wastes fuel and increases emissions.
Aggressive driving (speeding, rapid acceleration, and hard braking) wastes gas. It can lower your highway gas mileage 33% and city mileage 5%. Avoid high speeds. Driving 75 mph, rather than 65 mph, could cut your fuel economy by 15%. When you use overdrive gearing, your car’s 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.
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 car’s manufacturer. Using different motor oil can lower your gasoline 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 to 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 cold to start, can use twice as much fuel as one trip covering the same distance when the engine is warm.
