Aggressive driving (speeding, rapid acceleration and braking) wastes fuel. It can lower your fuel mileage by 33 percent at highway speeds and by 5 percent in the city. Sensible driving is also safer for you and others, so you may save more than fuel money.
Observe the Speed Limit
While each car reaches its optimal fuel economy at a different speed (or range of speeds), fuel mileage usually decreases rapidly at speeds above 60 mph.
Remove Excess Weight
Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your fuel economy by up to 2%.
Avoid Excessive Idling
Idling gets 0 miles per liter. Cars with larger engines typically waste more fuel at idle than do cars with smaller engines.
Use Cruise Control
Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save fuel.
b. Keep your car in shape
Keep Your Engine Properly Tuned
Fixing a car that is noticeably out of tune can improve its fuel mileage by an average of 4 percent, though results vary based on the kind of repair and how well it is done.
Keep Tyres Properly Inflated
You can improve your fuel mileage by around 3.3 percent by keeping your tyres inflated to the proper pressure.
Use the Recommended Grade of Motor Oil
You can improve your fuel mileage by 1-2 percent by using the manufacturer's recommended grade of motor oil.
c. Planning & Combining Trips
Combining errands into one trip saves you time and money. With a little planning, you can avoid retracing your route and reduce the distance you travel as well. You'll not only save fuel, but also reduce wear and tear on your vehicle.
Commuting
If you can stagger your work hours to avoid peak rush hours, you'll spend less time sitting in traffic and consume less fuel. If you own more than one vehicle, drive the one that gets the best fuel mileage whenever possible.
Car Pooling
If possible, take advantage of carpools. You can cut your weekly fuel costs in half and save wear on your car if you take turns driving with other commuters.
