What does it mean to limit the use of unleaded gasoline above No. 92?
1 Answers
The meaning of limiting the use of unleaded gasoline No. 92 and above refers to using gasoline with a grade not lower than No. 92. The selection of gasoline grades and precautions for refueling are as follows: Selection of gasoline grades: The common gasoline grades in China mainly include No. 92, No. 95, etc. The gasoline grade indicates the octane number in the gasoline. Gasoline with a higher octane number has better anti-knock performance. The grade of diesel is different from that of gasoline. The grade of diesel represents the freezing point. Precautions for refueling: Try not to wait until the fuel light comes on before refueling. Because the fuel pump is located in the fuel tank, the temperature of the fuel pump is relatively high during continuous operation, and immersion in fuel can effectively cool it down. When the fuel light comes on, it means that the fuel level is already lower than the fuel pump. If you wait until the light comes on every time before refueling, it will shorten the service life of the fuel pump. Too little fuel or running out of fuel may also burn out the fuel pump. If you drive more than 30,000 kilometers, you need to be more careful. When there is too little fuel, once the fuel pump sucks up the sediment at the bottom of the fuel tank, it is easy to block the fuel pump or cut off the fuel circuit.
