开车省油7技巧（7 skills in driving oil） Car 7 fuel-efficient High oil prices are a small expense for motorists who drive for long periods of time. As long as careful calculation, the same oil can run farther. Learn these 7 fuel-efficient strategies, you can do it. 1, choose low viscosity lubricating oil The new car is suitable for low viscosity lubricating oils. High viscosity of lubricating oil will increase engine load and increase oil consumption. The lower the viscosity of the lubricating oil, the more labor-saving engine, especially the cold car, the state of the engine encountered less obstruction, the more fuel-efficient. 2, control the speed The most fuel-efficient way is to travel at uniform speed. When the wind speed is low, the most fuel efficient speed is between 70~90 kilometers. Dont put it too low or too high. When the speed is low, the piston moves at low speed and burns incompletely. When the speed is high, the intake speed increases, which leads to the increase of intake resistance and the increase of fuel consumption. At the same time, dont step on the gas to speed up, dont slam the brakes. All this will only increase fuel consumption. 3, adjust the state of the tire The size of the tire pressure, the size of the tires, and the calibration of the tires affect fuel consumption. The standard tire pressure of each car is slightly different, usually written on the side of the drivers side door or on the fuel tank cover, usually between 2.4-2.7. After testing, according to the requirements of the tire pressure, can reduce fuel consumption by 3.3%. In addition, choosing a wider tire may make the car seem more Sports, but the wider the tyre, the greater the wheel resistance, it will consume more gasoline. What I have to say is that the steering wheel will lose fuel, and regular inspection is a good way. 4, grasp the engine start In situ hot actually dont need a car after the start, if not immediately accelerated in the car has just started a few minutes slow, l
