Changing N and D gears frequently can save fuel.

Now the oil price is soaring day by day, especially for automatic transmission owners, whose fuel consumption is not low, which brings them more fuel consumption than manual transmission owners. In addition to worrying about gas money, more and more car owners are beginning to be careful about the fuel economy of their cars. Mr. Luo, the owner of the car, took a group of riders to go on road trip during the May Day holiday. When he came back from a business trip, several car owners calculated the fuel cost and found that he was also driving an automatic car, but Mr. Luo's fuel cost was much less than theirs. Asked about the reason, Lao Luo readily told everyone about the fuel-saving methods he summarized.

Lao Luo, who often changes the "N" and "D" gears, tells everyone that the fuel consumption of automatic transmission cars is indeed higher than that of manual transmission cars, but the same automatic transmission cars will also produce different fuel consumption according to different driving habits of individuals, and even sometimes this difference is quite big. At one point, I used to wait for red lights, traffic jams or people who waited for a long time, but I was afraid of trouble. I stepped on the brake and put the gear in "D". When I need to start, I step on the gas pedal and leave. In fact, it is convenient to do so, but it unnecessarily increases fuel consumption. Now, no matter what the parking situation is, if the waiting time exceeds 1 min, put the gear in the "n" position, which can not only reduce the fuel consumption but also prevent the gearbox oil from overheating, thus protecting the gearbox. If the parking time exceeds 3 minutes, it is best to hang the "P" gear, which is fuel-efficient and environmentally friendly. Teacher Luo told everyone that he has been doing this all the time in road trip, and the effect is remarkable. Cars also need to be "lightweight". Lao Luo heard from an expert that every 5 kg increase in vehicle weight will consume 1% more gasoline. Therefore, before this road trip, Lao Luo carefully selected the equipment he needed and tried to choose "lightweight" equipment. Along the way, used and disposable' things' rushed out of the car without mercy. Try not to put things that are not needed in daily life in the trunk. This makes the car lighter and naturally saves fuel consumption. Keep the standard tire pressure and pay attention to ensure the normal tire pressure. Lao Luo told everyone that he usually takes a pressure gauge to check the tire pressure of his car every three to five times, because too high or too low tire pressure will increase the fuel consumption of the car, and more dangerously, too low tire pressure is more likely to cause a puncture. In addition, Teacher Luo also told everyone that abnormal wheel alignment will consume gasoline for no reason, so before leaving for road trip this time, he specially made a four-wheel alignment for the car, which not only ensured the safety of travel, but also effectively reduced fuel consumption.
