What is Reefer Fuel and How is it Different Than Regular Diesel for Trucks?

What Is Reefer Fuel?

Understanding Reefer Fuel and Its Uses

Reefer fuel is a fuel that is marked with a red dye in the United States. Like you are aware, on-road fuel diesel, and gasoline is usually subjected to a tax.

However, reefer fuel that can be identified by a distinctive red color is a form of diesel that is considered to be an off-road diesel

The red die marks it as fuel for off-road vehicles and equipment and therefore, doesn’t have road taxes included in the cost.

To clear the red die, would require a lot of fuel to dilute, and therefore, it will be very obvious when put in an on-road truck.

Reefer fuel is considered to be offroad equipment as it doesn’t power anything driving on a road.

If you happen to use on-road clear fuel in a reefer trailer or van, you should track and keep the receipt for the on-road fuel being used in the off-road unit as you can file for the fuel tax back. You will be required to show proof and therefore, you should consult your accountant.

Tax authorities usually check for vehicles using the fuel on the road. They do so using a black light that can spot any residue presence of the dye in the fuel and the major engine compartment.

The fuel is commonly used for agriculture use, construction fuelling, and other offroad equipment that aren’t used on the highway where fuel taxes is necessary.

The Peculiar Role of Reefer Fuel

Reefer fuel is meant to be used for the refrigerator unit of the heavy truck. It’s supposed to keep the trailer cool and should not be used for road purposes. This is because the on-road fuel is subjected to tax.

Since it’s used to keep the trailer cool and not to run the truck, it isn’t subjected to the on-road tax. This fuel is usually dyed to ensure that it’s untaxed and is only used for off-road fuel.

Using reefer fuel on the road is illegal and can lead to a fine of more than $10,000 depending on the state. Many states work very hard to prevent this type of tax avoidance.

On West Coast, the fuel is ultra-low sulfur fuel, meaning that it would not cause any maintenance problems when used in an engine. Depending on how old the fuel is, it can be low sulfur or high sulfur fuel.

Difference Between Reefer Fuel and Tractor Fuel

Reefer fuel refers to fuel that is used on refrigeration trucks. As an offroad fuel, it can also be used in construction, heating, agriculture, and other off-road equipment that isn’t used on the highway where the government requires fuel tax.

Tractor fuel on the other hand is the standard number 2 diesel. It’s a low-grade fuel that is in between gasoline and diesel when the distillation of crude oil is happening.

This refining technique that was developed during the World War 11 was turned into a more useful fuel. Power fuel was considered a higher grade of tractor fuel.

There are some types of low sulfur dials (with less than 500 parts per million sulfur fuel) and some high sulfur diesel with more than 500 parts for million sulfur that are still available in the marketplace. It is commonly used for boiler systems, heating oil, marine, and locomotive applications.
