Offroad diesel usually has 3-4 times the sulfur content of regular OTR diesel.

Every year MT state police do random checks. $1000 fine if caught with just a hint of red dye in your diesel.

I suspect this is incorrect. Every piece of machinery built in the last 15 years has required ultra low sulfur diesel by law. Maybe 20 years ago this was true. Today it is the same fuel with dye in it as mentioned.

Wrong. It has been ULSD since September 2006. The slowest to transition has been Railroad diesel and is "mostly" ULSD since 2015. Some outfits have resisted the change since they operate equipment 40-50-60 years old.

There are fuel companies selling a high sulfur content fuel I think they are just adding a additive and lubricant just like we add 2stroke to the non DEF trucks for more lubricant .
I even add Lucas upper cylinder stuff to the gas motors , figure all gas a garbage these day and a little snake oil can’t hurt to lube the injectors.
Its all the same ULSD just a different color for a different application . I’m my state you had to be runner commercial in order to be dipped , I got stopped years ago by DOT in a regular pickup and they wanted to dip and said you don’t see any DOT numbers or commercial plates so you would have to get a warrant if i want to push it .
I was legal … they let me sit for a minute parked and there was a Dunkin’ Donuts so i got out and was walking to get a coffee , they could see i was in no hurry and they yelled get going … small fish and I was not running any off highway fuel .

I run a farming operation and the red dyed fuel is exactly the same as non dyed on road. My equipment has the same requirements for USLD as our pickups.

That red dye is very persistent, you can add a gallon if it to a 50 gallon tank, run through 5 tanks and there will still be a hint of red. When I first got my tractor it had offroad in it, but I could not get offroad for it so used the green stuff. 2 years later the fuel still had a red tint. The fine can be up to $10,000 and jail time, so use it at your own risk. Really you are only saving a few pennies using it since the fuel is the same price as the green stuff minus taxes.

Montana Highway Patrol ... No state police... must not be local. DOT is the agency that regulates and checks for red dyed diesel.
