What is No. 0 Oil?
2 Answers
No. 0 oil refers to light diesel fuel. No. 0 diesel starts to crystallize at 0°C, as diesel solidification is termed crystallization. Diesel grades are named based on the freezing point of the oil product, hence No. 0 diesel begins to crystallize at 0°C. Diesel is a light petroleum product and a complex hydrocarbon mixture, serving as fuel for diesel engines. It is mainly composed of diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking, and can also be obtained from shale oil processing and coal liquefaction. The selection of diesel is determined by the temperature during use; No. 0 diesel should only be used when the temperature is above 4°C.
When it comes to No. 0 diesel, it's actually the most common type available at gas stations. I've been fueling my truck with it for years. Its freezing point is exactly 0°C, making it suitable for year-round use in southern regions - affordable and practical. But you must pay special attention to seasonal changes. When temperatures drop below 5°C, you need to switch to diesel with a lower grade. I once forgot to switch in winter and ended up stranded on the road with frozen fuel lines, shivering from the cold. Now I always check the weather before refueling and keep -10 and -20 grade diesel ready in advance. By the way, many gas stations now differentiate between China V and China VI standards. For China VI vehicles, make sure to use fuel labeled with 'VI' to avoid engine damage.
