What is difference of reefer and tractor fuel?

Reefer fuel is specifically used to power refrigeration units on trucks and trailers that transport perishable goods, ensuring they remain at the required temperature during transit. Tractor fuel, on the other hand, refers to the diesel used to power the truck's engine for driving. While both types of fuel are essential for the transportation of goods, they serve different functions within the logistics process. Additionally, reefer fuel often has specific formulations and regulations to meet environmental and efficiency standards.
