Reefer fuel is a specialised diesel for refrigeration units on trailers
Reefer fuel is a specialised type of diesel fuel that powers the refrigeration units of refrigerated trailers, often called "reefers". These trailers are equipped with refrigeration systems that rely on reefer fuel to maintain a consistent and cold temperature inside, ensuring that perishable goods, such as food and pharmaceuticals, stay fresh and avoid spoilage during transportation.
Reefer fuel has a high flash point, making it less likely to ignite easily and ensuring the safety of the refrigeration process. It is also formulated to perform effectively in cold environments, allowing it to maintain the low temperatures required to preserve the goods inside the trailer. The longevity of reefer fuel can vary depending on factors such as the make and model of the reefer unit and the size of the load. On average, a reefer unit consumes around 0.5 to 1 gallon of fuel per hour of operation, with some units consuming up to 3 gallons per hour.
As reefer fuel is considered an off-road fuel, it is not subject to the same taxes as on-road diesel fuel. This makes reefer fuel a more cost-effective option, with prices varying depending on the supplier. Reefer fuel is available at most gas stations that service diesel trucks, and it can also be found at all-terrain vehicle service and sales companies.
The cost of reefer fuel per mile can vary, but as of December 2022, the national average cost was $2.74 per mile. Reefer trucks typically burn around 0.5 to 1 gallon of fuel per hour, with a 50-gallon capacity, and need to be refuelled every 2 to 4 days. The fuel efficiency of reefer trucks may also depend on factors such as proper maintenance, ambient temperature, and the overall condition of the trailer.

These trailers are used to transport perishable goods and require two types of fuel: one for the engine and one for the refrigeration system. Reefer fuel is specifically designed for the refrigeration system.
Reefer fuel is typically cheaper per gallon than regular diesel. This is because reefer fuel is exempt from certain taxes that apply to on-road fuel. In the United States, on-road diesel can be taxed up to $0.50 per gallon in state and federal taxes. Reefer fuel, on the other hand, is restricted to off-road use and is not subject to these taxes. This makes it a more cost-effective option for powering refrigeration units.
However, it is important to note that reefer fuel is not intended for use in on-road vehicles, such as trucks. Using reefer fuel in the primary engine tanks of a truck is strictly prohibited and can result in significant fines for both the operator and the trucking company. These fines can be as high as $10,000. Therefore, it is crucial to understand the distinction between reefer fuel and regular diesel fuel to avoid any legal and financial consequences.
The cost of reefer fuel may vary depending on the supplier, and it is important to consider factors such as capacity, efficacy, durability, and safety features when choosing a reefer fuel supplier. Additionally, proper maintenance of the refrigeration unit is essential to optimize fuel efficiency and minimize costs. A poorly maintained unit will require more reefer fuel, increasing overall expenses.
In summary, while reefer fuel is less expensive per gallon than regular diesel due to its tax-exempt status, it is restricted to off-road use and should not be used to power on-road vehicles. By understanding the regulations and properly managing reefer fuel usage, companies can control their costs while ensuring the timely and temperature-controlled delivery of perishable goods.

Reefer trucks use 0.5-1 gallon of fuel per hour
Reefer trucks, which are used for transporting perishable goods, require two types of fuel. One type powers the engine, and the other powers the refrigeration system. Reefer fuel, which powers the refrigeration system, is used at a rate of around 0.5-1 gallon per hour. This means that over an 11-hour driving period, a reefer truck will consume 5.5-11 gallons of reefer fuel. Over a 24-hour period, this increases to an average of 18 gallons.
The amount of reefer fuel used can vary depending on several factors. Firstly, the age and maintenance of the refrigeration unit can impact fuel consumption, with older or poorly maintained units requiring more fuel. Secondly, the ambient temperature in the regions driven through can affect fuel efficiency. Thirdly, the overall condition of the trailer can impact fuel efficiency, with older trailers potentially being less efficient.
Due to the high fuel requirements of reefer trucks, understanding and managing reefer fuel usage is critical for companies regularly transporting cold shipments. Properly managing reefer fuel usage can help control costs while ensuring that cargo is delivered on time and at the right temperature.
The cost of reefer fuel can vary depending on the supplier. Reefer fuel is generally less expensive per gallon than regular diesel, as it is not subject to the same taxes.

Fuel efficiency depends on maintenance, ambient temperature, and trailer condition
Reefer fuel is a special type of tax-exempt diesel used for off-road and refrigerated trailer use. It is essential for companies that transport temperature-controlled goods. Reefer trucks have two types of fuel tanks: one for powering the refrigerator and another for powering the engine. Reefer fuel is generally less expensive per gallon than regular diesel. As of December 2022, reefer trucks were found to burn around 0.75 gallons of fuel per hour, with a 50-gallon capacity, and needed refuelling every 2 to 4 days. However, the fuel efficiency of reefer trucks depends on various factors, including maintenance, ambient temperature, and trailer condition.
Maintenance plays a crucial role in fuel efficiency. A poorly maintained or older unit will require more reefer fuel. Regular maintenance ensures that the refrigeration system is functioning optimally, which can help maintain fuel efficiency. Proper maintenance includes tasks such as checking the compressor, evaporator, and condenser for any issues.
Ambient temperature significantly impacts fuel efficiency. As the temperature decreases, fuel efficiency tends to decrease as well. This is because colder air is denser, increasing aerodynamic drag on the vehicle, especially at higher speeds. Additionally, during colder temperatures, engine and transmission friction increase due to cold engine oil and other cold drive-line fluids. This results in a longer time for the engine to reach its most fuel-efficient temperature, affecting shorter trips more significantly.
Trailer condition is another factor influencing fuel efficiency. Older trailers may have lower efficiency due to wear and tear over time. The overall condition of the trailer, including the insulation and any necessary repairs, can impact the amount of fuel required to maintain the desired temperature. Proper trailer maintenance and ensuring the trailer is in good condition can help optimize fuel efficiency.
Other factors that can affect fuel efficiency include freight requirements and the efficiency of the reefer system. Reefer systems can vary widely in efficiency, with some using as little as half a gallon of fuel per hour, while others may use up to one gallon. By considering these factors and taking appropriate measures, companies can optimize fuel efficiency and reduce operational costs associated with reefer fuel usage.
