Perhaps, many car owners still don’t know that there are many tips for car refueling. If you don’t know these tips, believe me, you will definitely suffer!
More fuel in the morning and evening
The temperature in the morning and evening is relatively low throughout the day. Gasoline expands with heat and contracts with cold. Gasoline is charged by volume. When the temperature is low, the density of gasoline is relatively high, the mass per unit volume is relatively large, and more fuel is added. Don't talk about taking a small advantage, how much money is saved, I just want to silently say: Is your old man a local tyrant? !
Turn on the yellow light and refuel? NO! NO! NO!
Don't refuel after the yellow light is on. A yellow light indicates that the gasoline has been lower than the fuel pump. In this case, the continuous working temperature of the fuel pump is too high, and it is not soaked in the fuel, and the temperature cannot be effectively reduced. This will reduce the life of the fuel pump or even burn the fuel pump directly for a long time. For driving more than 30,000 kilometers, you need to be more careful. If the oil pump pumps up the sediment at the bottom of the fuel tank when there is too little oil, if you block the oil pump or block the oil path, you will be lucky. If you don't do it, it will lead to misfortune.
If the owner’s car is used for commuting to and from get off work, and it is more convenient to refuel, there is no need to fill up the fuel every time. This will only increase the load of the car without any other practical significance.
Increase the oil mark in the urban area without saving
When refueling, gasoline with different labels should be selected according to the different compression ratio of the engine. 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.
If the car often runs at speeds below 60km, it is suitable to add No. 93 gasoline. If you run at speeds above 100 for a long time, you should add No. 97 oil to ensure better performance of the car engine.
