off road diesel

I wouldn't recommend it. An engine that is designed to run on the ultra-low sulphur diesel can be severely damaged by running a high-sulphur fuel.

 

Yes it is. Companies keep track of all reefer fuel purchases and if the driver puts regular on road fuel in the reefer tank, they file for a refund of the road tax.
Some truckstops have separate pumps for off road diesel, and it may be dyed RED. It is illegal to put RED diesel in the truck fuel tanks and a hefty fine is imposed if caught.

 

Offroad diesel is the same as road diesel except offroad has no highway taxes since it is not meant to be used to propel a vehicle down the state and federal funded highways and roads the taxes are used to maintain. So yes, you want to be using offroad diesel or tax free diesel in the reefer for sure.

I have a small gas generator, I write off the gasoline for it as it is used in an offroad capacity.

 

Hasn't been "high-sulphur" for years. Even new farm equipment has all of the emissions crap on it these days requiring ULSD.

 

Off road is in all my reefer trailers, never had any problems. And yes, perfectly legal.

 

Only difference is the color dye to identify it.....its all the same now...from on road to off to home Heating...All ULSD....dyed to identify what purpose its used for......And to catch you runnin off road etc in truck......and of course depending on state u purchase in how much bio mix has been added....

 

As a fuel hauler, I load red dye sometimes. It's the same exact product as clear diesel, except heavy doses of potent red dye are injected into the loading arm at intervals. This is used for farm equipment, tractors and everything that runs on diesel that does not utilize public roads , so for example a generator. I think a reefer will probably be OK but check your company's policies.

 

So the red dye diesel is also ultra low sulfur diesel and would in theory run perfectly in any engine. But if the DOT sticked your tank and found that red dye, you'd be well screwed.
