Diesel oil is divided into vehicle diesel oil and ordinary diesel oil. The quality requirements of automotive diesel oil are relatively high, followed by ordinary quality. Fuel oil does not belong to diesel oil, and is mainly used for boiler heating. The main difference between fuel oil and diesel oil is the difference in sulfur content and cetane number. Fuel can not be used as truck diesel, which will make the truck emission standards fail to meet the standards and easily damage the vehicle power system. Fuel and diesel have different requirements and standards, so fuel cannot be used as truck diesel.
