Can You Put Reefer Fuel in a Diesel Truck?

When it comes to fueling your diesel truck, it’s important to know which type of fuel is appropriate for your vehicle’s engine. Reefer fuel, also known as refrigeration fuel, is a fuel specifically designed for refrigerated trailers. It is used to power the refrigeration units that keep perishable goods at the required temperature during transportation.

While reefer fuel may seem like a potential substitute for diesel fuel, it is important to note that they are not the same and cannot be used interchangeably. Here’s why:

1. Different Fuel Compositions

Diesel fuel and reefer fuel have different compositions and are formulated to meet the specific needs of their respective engines. Diesel fuel is designed to ignite under high compression in a diesel engine. On the other hand, reefer fuel is formulated to burn at lower temperatures to power the refrigeration units.

2. Varying Fuel Additives

Another crucial difference lies in the additives present in each fuel type. Diesel fuel contains additives that enhance its lubrication properties, prevent oxidation, and winterize the fuel for cold weather. Reefer fuel, on the other hand, may contain additives to improve its low-temperature burning characteristics and reduce emissions specific to refrigeration units.

3. Engine Compatibility

Using reefer fuel in a diesel truck can have detrimental effects on the engine. Diesel engines are designed to operate with the properties of diesel fuel, such as its viscosity and combustion characteristics. Feeding the engine with a fuel not intended for its design can lead to poor performance, reduced fuel efficiency, and potential damage to the engine components.

4. Legal Compliance

Putting reefer fuel in a diesel truck may also lead to compliance issues. Government regulations dictate the types of fuel that are approved for use in different types of vehicles. Using non-compliant fuel can result in hefty fines and penalties, not to mention the potential environmental impact.

It is essential to follow the guidelines and recommendations provided by the manufacturer of your diesel truck. The manufacturer’s manual will specify the appropriate fuel type for your vehicle, including any required fuel additives.

What to Do If You Accidentally Put Reefer Fuel in a Diesel Truck?

Accidents can happen, and if you mistakenly put reefer fuel in your diesel truck, it’s crucial to take immediate action:

  • 1. Do not start the engine: Starting the engine can cause the reefer fuel to circulate through the fuel system, potentially causing damage. Prevent further damage by avoiding engine ignition.
  • 2. Drain the fuel tank: Contact a professional mechanic or a fuel removal service to drain the reefer fuel from the tank. They will ensure proper disposal and advise on any necessary repairs or maintenance.
  • 3. Inspect the fuel system: After removing the incorrect fuel, it is crucial to inspect the fuel system for any potential damage. This step is especially important if the reefer fuel had already circulated through the system.
  • 4. Refill with the correct fuel: Once the system is verified to be in good condition, refill the tank with the appropriate diesel fuel recommended by the manufacturer.
  • 5. Seek professional advice: If you are unsure about the damage caused or need assistance, consult with a qualified mechanic who specializes in diesel engines.

By taking prompt action and following the necessary steps, you can minimize the potential damage caused by using the wrong fuel in your diesel truck.
