Loulan, come on, 92 or 95?

Loulan refueling officially designated No.92 gasoline and recommended No.95 gasoline, which can prevent the engine from knocking. The biggest difference between 92 # gasoline and 95 # gasoline is the different octane number of gasoline. The higher the octane number, the stronger the antiknock performance of gasoline.

Generally, automobile engines have a specified compression ratio, through which the corresponding gasoline model can be selected. When the compression ratio is 8 to 10, choose No.92 gasoline, and when the compression ratio is above 10, choose No.95 gasoline.

If 92 # gasoline is used in an engine with high compression ratio, it will knock the engine of the vehicle, leading to unstable idle speed, reduced power, increased fuel consumption, even bending the engine valve and even damaging the throttle cover. Therefore, a car that uses No.95 gasoline must not use No.92 gasoline for a long time unless the car runs out of gas halfway. Million car purchase subsidy
