Hello everyone, I'm Xiao Li. Many people feel that the fuel consumption of automatic transmission cars is directly determined by the engine and gearbox, and the driver cannot intervene, but in the same car, some people drive high fuel consumption, and some people drive fuel consumption is particularly low. In fact, the automatic transmission model does not cost fuel, and our driving Xi has a lot to do with it, today Xiao Li will tell you a few fuel-saving skills that I usually summarize by driving, I hope to help everyone.
First of all, in the process of using the car, we must not warm up the car too much. I have already told you about the hot car before, we can't leave immediately with the fire, but we can't idle the hot car for too long, the correct way is to wait for twenty or thirty seconds with the fire on before using the car. Because the oil will flow to the ground after the car stops, even if the oil filter element has the function of preventing oil backflow, but it cannot be kept all parts can be kept overnight and there is oil lubrication, especially the turbine These parts are installed in a high place, and the oil on the turbine flows to the place after stopping overnight. If we start the car and leave immediately, it will cause the oil to not lubricate every part in time, resulting in wear and tear on the engine. After a few years of use of such a car, there will be the problem of high fuel consumption and weak power. However, excessive in-situ heating will also lead to an increase in carbon deposition inside the engine, which will affect the compression ratio of the engine over time, and will also lead to the problem of high fuel consumption and weak power of the engine. Therefore, the correct way to warm up the car is to wait for twenty or thirty seconds, and the engine oil has fully lubricated the engine, and the car can be used. 
Many novice friends on the road driving the accelerator and brake are slammed on, see the road is relatively empty, just step on the accelerator, and then encounter a situation on the road and step on the brake slammed. This method of driving is extremely fuel-intensive, and a lot of the oil burned by the engine is wasted during the process of slamming the accelerator and slamming the brakes. When you step on the accelerator, the speed of the engine will be pulled higher, usually the gearbox will change gears at 2000 rpm, but when you step on the accelerator, the gearbox will wait until 2500 rpm to change gears, and sometimes it will even cause the engine to idle, which will waste oil. Slamming on the brakes will cause part of the engine output to be offset by the friction of the brakes, which will not be used to push the car forward, and will also waste fuel, and over time, your car's fuel consumption will be particularly high. We must learn to use the throttle to control the speed, try to reduce the purpose of stepping on the brakes, drive without stepping on the accelerator, when the engine exceeds 2000 rpm, slightly loosen the throttle and then step on it, so that the gearbox can change gears in advance and make the drive smoother.
When waiting for the traffic light, if the traffic light waiting time is particularly long, then we will switch the gear to n gear and wait, I do not recommend everyone to turn off the engine and wait for the traffic light, because the use of electrical appliances in the car after the ignition is turned off will cause the battery to lose power, and the engine will not be able to use the air conditioner in the car in the summer, which is also very uncomfortable. By switching back to neutral, the engine can be injected less fuel and save fuel. I believe that everyone will find that if you hang the traffic lights such as D gear, the gearbox is always in a suffocated state, and the engine speed will be much higher than when idling, which proves that the engine is not idle at this time, and the fuel consumption will definitely be higher.
Fuel saving is a process that accumulates over time to see the effect, we develop a good Xi habit in the process of driving is the most important, we must remember the 3 skills that we told you above, novices learn these 3 skills, and can also drive low fuel consumption, I hope my explanation can help you.
