What brand of diesel should be added to diesel vehicles in low temperature weather?

The freezing point of 10 diesel oil is-10 degrees, and it is used at-1-9 degrees.

Diesel oil is classified according to its freezing point. Light diesel oil has six grades of 5,0,-10, -20, -35 and -50, and heavy diesel oil has three grades of 10, 20 and 30. The choice of diesel oil is based on the temperature when it is used.

For example, when the temperature of-10# diesel oil reaches below-10℃, wax deposition will occur, which will affect the normal operation of diesel engine. Therefore, each region should choose the appropriate diesel oil label according to the law of temperature change, and these diesel oils can not be distinguished by naked eyes, and can only be distinguished by some technical tests.

According to different densities, for petroleum and its processed products, it is customary to call those with low boiling point or low boiling point range light, and vice versa. Generally divided into light diesel oil and heavy diesel oil.

Diesel oil can be divided into light diesel oil (boiling point range is about 180-370℃) and heavy diesel oil (boiling point range is about 350-4 10℃). Ignitability and fluidity are the most important properties of diesel oil, and their technical indexes are cetane number and freezing point respectively. The current diesel specification in China requires that the sulfur content should be controlled at 0.5%- 1.5%.

Like motor gasoline, diesel has different brands.

Diesel oil is classified according to its freezing point. Light diesel oil has six grades of 5,0,-10, -20, -35 and -50, and heavy diesel oil has three grades of 10, 20 and 30.

The choice of diesel oil is based on the temperature when it is used. Diesel vehicles mainly use the latter five brands of diesel, and choose 0# diesel when the temperature is above 4℃; Choose-10# diesel when the temperature is 4℃-5℃; When the temperature is -5℃- 14℃, choose -20# diesel oil.

When the temperature is-14℃-29℃, choose -35# diesel oil; If the brand diesel oil is above the above temperature, the fuel system in the engine may deposit wax, blocking the oil circuit and affecting the normal operation of the engine.
