Tips and Precautions for Car Refueling
1 Answers
Car refueling tips and precautions are as follows: 1. Using higher octane fuel in urban areas does not save money: The octane rating of gasoline only indicates its octane number, and different octane grades should be selected based on the engine's compression ratio. Mid-range cars with a compression ratio between 8.5~9.5 generally should use 93-octane gasoline; cars with a compression ratio above 9.5 should use 97-octane gasoline. Currently, most domestic cars have a compression ratio above 9, so it is best to use 93 or 97-octane gasoline. 2. Do not wait for the fuel warning light to come on before refueling: Before driving, check the fuel gauge and calculate whether refueling is needed during the trip based on the distance and the fuel gauge reading. It is advisable to refuel in advance rather than waiting for the fuel warning light to come on. The fuel pump is located inside the fuel tank and operates at high temperatures when running continuously. Being submerged in fuel helps cool it effectively. When the fuel warning light comes on, it means the fuel level is below the fuel pump. Consistently waiting for the light to come on before refueling will shorten the fuel pump's lifespan, and having too little fuel in the tank may even cause the fuel pump to burn out. 3. Refuel by the liter: It is recommended to refuel using the "liter" as the unit of measurement and to coordinate with the gas station staff in advance to avoid unnecessary expenses.
