Teaching you tips. How to save money when refueling in a car
1. Tips for refueling in a car: Don’t turn on the yellow light and then refuel
“ Before driving, the owner first checks the oil meter and calculates whether he wants to refuel on the way based on the distance of the itinerary and the scale of the oil meter. The owner can refuel in advance, and do not wait until the oil lamp is on before refueling. ”
Because the oil pump is located in the oil tank, the temperature of the oil pump is high when it is continuously working, so immersed in the fuel can effectively cool down. When the oil lamp is on, it means that the oil level is lower than the oil pump. If you wait for the light to turn on before refueling every time, it will shorten the service life of the oil pump. If the oil tank stores too little oil, it may burn the oil pump.
If you travel more than 30,000 kilometers, you need to be more careful. If the oil storage is too little, once the oil pump pulls up the sediment at the bottom of the oil tank. If it simply blocks the oil pump or blocks the oil circuit, it is considered lucky.
If the owner usually drives in the city, it is used for commuting and getting on duty, and it is more convenient to refuel, there is no need to fill it up at once. A full tank of oil in the vehicle will increase its weight and increase fuel consumption. According to the current oil price, you can add 200 yuan or 25 liters of oil at a time.
2. The secret to refueling in automobiles: increasing the standard oil in the city does not save
The height of the gasoline label only indicates the octane number of the gasoline. Different label gasoline should be selected according to the engine compression ratio. Mid-range cars with compression ratios between 8.5 and 9.5 should generally use No. 93 gasoline; cars with compression ratios greater than 9.5 should use No. 97 gasoline. At present, the compression ratio of domestic cars is generally above 9, and it is best to use No. 93 or No. 97 gasoline.
Vehicles usually drive in the city, and half of the driving speed is less than 60km. Adding 97 gasoline will not have obvious benefits than 93 gasoline. Only when driving at a long time of running at a speed of more than 100km/h, if you want the engine to perform better, you should use No. 97 gasoline.
3. The secret to refueling in the car: the quality of refueling in the morning and evening is better
The refueling time is very tricky. Generally speaking, the temperature in the morning and evening is relatively low, and the gasification point of gasoline is relatively low, so refueling should be done in the morning and evening. Gasoline has the properties of thermal expansion and contraction, and gasoline is charged by volume. When the temperature is low, the gasoline density is relatively high, the mass per unit volume is relatively large, and there is more fuel. Car owners can prepare a pair of stockings in the trunk of the car. If the car owner is forced to refuel in a place where he is mentally unsure, putting the stockings on the oil gun can effectively filter impurities.
Warm reminder: When refueling a car, you need to choose the right number according to the requirements. Add as many as you should add. The higher the gasoline, the better, but the car is suitable for you.
