With the continuous rise of oil prices, the era of oil prices of 5 yuan has long gone, and many car owners will blindly listen to others' so-called fuel-saving techniques in order to save fuel. In fact, many of these fuel saving techniques are nonsense, not only can not save fuel, but even increase fuel consumption. Today Xiaobian will come to popularize a few seemingly fuel-saving driving skills that are actually not fuel-efficient.
First, refuel and add half
Compared with the era of oil prices of 5 yuan, today's oil prices are really beyond the reach, and many car owners do not even dare to say that they are full when refueling, for fear that they cannot afford to pay. And some car owners choose to add half a box when refueling in order to save fuel, he feels that only adding half a box of fuel to the car is light, so it will save fuel. This does sound very reasonable, but it is not. Adding half is not much more than filling up, which is at most tens of milliliters. And adding half a tank of fuel can only be driven for a long time, and then you have to go to the gas station again. The oil required for this extra trip is completely comparable to this half tank of oil, so everyone must not believe that adding half a tank of oil can save fuel.
Many people also think that going to the gas station in the morning or at night to refuel will make more oil. Because the morning and evening are cooler, the noon is hotter, according to the principle of thermal expansion and contraction, the gasoline will expand at noon, and the oil added to the tank will naturally be less. The layman sounds like this, but in fact, the gasoline at the gas station is basically not affected by the temperature difference, so whether it is to add gasoline in the morning and evening or to add gasoline at noon, there is no difference at all.
Second, drive slowly to save fuel
Many people think that driving a gentler car must be a little more fuel-efficient than driving a little harder, because when driving a little harder, you need to step on the accelerator brakes with a big foot, which will lead to an increase in the fuel consumption of the car, and the fuel consumption of driving a little gentler will be lower. In fact, this idea is wrong, driving too slow will also increase the fuel consumption of the car, because driving too slow will lead to the mismatch between the speed and gear, so not only cost fuel, but also the damage to the car is also very large, so we usually do not drive a slow car when driving.
Third, high gear and low speed driving
It is well known that the faster the engine speed of the car, the more fuel is used, and the more fuel the car consumes. Therefore, many car owners will choose high gear and low speed in order to save fuel, so that they can achieve the purpose of fuel saving. In fact, this approach is wrong, because the car engine works in the low speed range for a long time, which will undoubtedly increase the burden on the engine, and at the same time, it will also make the gasoline burn insufficiently and form carbon deposits, and the car will accumulate carbon for a long time and lead to increased fuel consumption.
Fourth, turn off the ignition when waiting for the traffic light
When we usually wait for traffic lights, it is inevitable that there will be several minutes of waiting because of traffic jams, and many car owners will turn off when waiting for traffic lights in order to save fuel. In fact, this practice can not achieve the purpose of fuel saving at all, and the fuel consumption of the ignition moment is more than the fuel consumption of one minute of idle speed. The most important thing is that if the red light suddenly turns to a green light, we still have to restart the vehicle, which is a waste of time.
The above few wrong fuel saving techniques, have you ever been tricked?
