Does diesel come in 92 and 95 octane ratings?

Diesel does not come in 92 and 95 octane ratings; only gasoline does. Here is some relevant information about diesel: 1. Diesel is classified into six grades based on its freezing point: 5, 0, -10, -20, -35, and -50. 2. Diesel is generally used in engines for trucks or buses. The selection of diesel grade mainly depends on the ambient temperature. When the temperature is above 4 degrees Celsius, 0-grade diesel can be used; when the temperature is between -5 and 4 degrees Celsius, -10-grade diesel can be used; when the temperature is between -14 and -5 degrees Celsius, -20-grade diesel can be used; when the temperature is between -30 and -14 degrees Celsius, -35-grade diesel can be used.
As a car enthusiast, I always talk about fuel knowledge at car meetups. Diesel doesn't have numbers like 92 and 95; those are octane ratings for gasoline, indicating anti-knock performance—the higher the number, the more expensive but suitable for high-performance cars. Diesel is completely different, categorized as No. 0, -10, -35, etc., where the number represents the freezing point temperature. For example, -10 diesel won't freeze at -5°C. I remember last winter when my friend drove in the north without switching to winter diesel, the fuel lines froze solid, costing him days and thousands in repairs. This reminds us to choose the right seasonal diesel grade—don't skip checking the label. It affects engine lifespan and fuel efficiency, since diesel engines rely on high-pressure compression ignition. Mixing in gasoline can damage the injectors. Nowadays, many gas stations offer low-sulfur eco-friendly diesel, so always read the specs when refueling—don't just guess.
