Most fuel Efficient Cars in the World

21. DON T BUY PREMIUM FUEL
Resist the urge to buy higher octane gas for premium performance, unless the vehicle requires it. Octane has nothing to do with performance; it merely indicates the volatility factor in the combustion chamber. Unless your vehicle owner s manual specifically requires it, don t use premium fuel.
22. DRIVE AT THE SAME SPEED
We tend to usually speed up and down during a bad traffic jams. Ever noticed how trucks tend to roll along at the same leisurely pace? A constant speed is a sure shot to save some extra fuel.
23. GET BACK TO NATURE
Late November and early December is the best time to enjoy the nature. Shut off that air conditioner, open the windows and enjoy the cool breeze. It may be a tad bit uncomfortable for some who is used to the AC, but trust us with windows rolled down you will not just stay connected with nature but will also save fuel big time.
24. STAY OFF THE BLING
Adding accessories to your car might make you look cool but it could also lead to extra fuel consumption. For example, a wider stock tires will create more rolling resistance and decrease fuel economy.
25. CHECK YOUR AIR FILTER
A dirty air filter restricts the flow of air into the engine, which harms performance and economy. Air filters are easy to check and change: See your owner s manual for instructions. Remove the filter and hold it up to the sun; if you can t see light coming through it, you need a new one.
