What is the difference between No. 0 and No. -10 diesel?

[OAndres]

The differences between No. 0 and No. -10 diesel are as follows: 1. Different freezing points. Diesel is graded by freezing point, with light diesel having six grades: 5, 0, -10, -20, -35, -50. The freezing point of No. -10 diesel is -10 degrees Celsius, while that of No. 0 diesel is 0 degrees Celsius. 2. Different applicable temperatures. The selection of diesel should be based on the temperature during use. Choose No. 0 diesel when the temperature is above 4°C; choose No. -10 diesel when the temperature is between 4°C and -5°C. If the selected diesel grade is higher than the above temperature, the fuel system in the engine will form wax, block the oil circuit, and affect the normal operation of the engine. 3. Different compositions. In terms of composition, No. -10 diesel has a lower paraffin content than No. 0 diesel, and its thickening temperature is also lower, allowing it to be used normally at minimum temperatures above -5°C.
