Maintain Vehicle Efficiency: Regular maintenance as prescribed by the vehicle owner’s manual will help your vehicle achieve its best fuel economy. Some overlooked maintenance items, such as a dirty air filter and under-inflated tires, can increase your fuel cost up to 13%. When replacing your tires, replace them with the same make and model as the tires that were on your vehicle when it was new.
Avoid aggressive driving / Drive at the Speed Limit: – Do you know aggressive driving can reduce fuel efficiency by up to 33% on highways and 23% in city. Excessive braking increases friction and thus reduces efficiency of the engine.
Use right gear for right speed: Lower gears in a vehicle are meant for lower speeds and higher gears for higher speeds. Engine has to work much harder if speed is high at a lower gear, which decreases efficiency. Every vehicle, depending on the size of the engine has an optimum speed to achieve maximum efficiency at various gears.
Reduce Air Conditioner Use / Close Windows: Using the air conditioner increases fuel cost from 13% up to 21%. If it’s cool enough, use the flow-through ventilation instead of rolling down the windows or using the AC.
Minimize Vehicle Idling: Today’s vehicles are designed to warm up fast. Avoid idling when you can. If the wait is longer than 10 seconds, the best thing is to switch off the engine.
Watch your speed : Fuel consumption of car depends on various factors: aerodynamics of the car, friction on the road, efficiency of the engine, etc. When speed increases, the force of air against the movement of car increases. The friction on the road also impacts. So try keeping speed between 60 and 80 kmph depending on the kind of road you are driving.
Eliminate Extra Wind Resistance and Weight: Using a loaded roof rack increases fuel consumption. Carry the load inside your vehicle if you can. Removing unnecessary weight is better still.
Avoid riding the clutch pedal: The purpose of a clutch is to connect or disconnect engine to the gearbox. If the clutch is pressed lightly, the connection between the two becomes slippery, and thus the acceleration is poor. This can result in significant decrease in efficiency, as the power generated by the engine will not pass on completely to the gearbox to move the vehicle.
Use Carpooling / Public Transit / Non-Motorized Options: Ride the bus, carpool, bicycle or walk instead of driving alone. Sharing a ride to work with a friend or two effectively doubles your fuel economy for the trip.
