1. Less use air conditioning
According to incomplete statistics, use air conditioning or not, fuel consumption differences reach 1-1.5L/100km; air temperature 1°C per low fuel consumption gap between 0.05-0.1L/100km. If the temperature is allowed, should try to roll down the window. However, not every time turn off air conditioning: when the speed is below 64km/h, roll down the windows, turn off air conditioning; When the speed exceeds 72km/h, should close the window open air condition, because air resistance than air conditioning consumes more fuel. Outside temperatures raise, no air conditioning is a difficult, but the temperature of 26 °C will not feel hot or cold temperatures.
2. Attention to tire pressure
Under the premise of security, add more gas which is the practice of many older drivers. Slightly higher tire pressure does help to reduce fuel consumption, but the other side is easy to puncture. Winter maybe you can try, but absolutely not the summer, because the summer is most easily puncture season throughout the year. Many owners in order to reduce the chance of summer puncture deliberately reduce tire pressure, it will also not need, in the case of under inflated tire pressure not enough, 4 tires every tire pressure drop 1psi, fuel economy index lost about 0.3%. It is worth mentioning that do not solely rely on the tire pressure monitoring system (TPMS) to detect whether tires is inflated, it is recommended to use the meter tested once a month.
3. Select the correct oil
What can be save, the engine oil should not be saved. Recommended to use the manufacturer’s recommended grade of oil, or higher than the manufacturer’s recommended grade of oil. Correct selection of the oil, reducing the friction of the engine can be maximized. Thereby reducing the workload of the engine helps to improve fuel economy 1-2%. In addition, different oil operating temperature range is not exactly the same. One must be careful before you buy.
4. Tighten the fuel tank cap
Petrol likely to be volatile, particularly in summer, so after each refueling, remembers to tighten your fuel cap. According to a report by the U.S. Discovery Channel, this wasted fuel every year up to 560 million liters. Fuel tank cap is missing or not tightened. It will directly reduce fuel economy by 1% to 2%.
5. Avoid frequent acceleration
High temperatures, the owner easily upset, compared to other seasons, will do more to increase fuel consumption actions, such as: step on the throttle, increase speed; frequent subtraction block, the pursuit of „sense of control“; frequent changes lane at high speed, continuous overtaking. Frequent subtraction block will increase vehicle fuel consumption in urban driving, speeding, acceleration, braking and other actions can reduce mileage by 5%, while on the highway, this figure up to 33%. In everyday driving the process, you should try to keep the vehicle at a constant speed, avoid frequent shifting, the appropriate use of high gear can effectively improve the fuel economy on the highway, using high gear can reduce engine speed, and fuel efficiency can simultaneously reduce engine wear.
