Red diesel on vehicles on the roads?

I have not seen red diesel personally, because the people I know who run farms buy the usual road-taxed fuel and keep a tally of how much they buy for off-road use here in Texas (form 06-106) for a refund from the state. It makes life easier for them, since they just need one fuel tank, and there is no chance of running the wrong fuel in a vehicle on the road.

However, this weekend at a local eatery, I overheard people talking about buying "reefer" fuel (which is red-dyed) at truck stops and saying how much money they saved over conventional diesel, and that nobody will ever know.

Is this a common thing?

    I do and I admit it. My truck fuel and tractor fuel all come from the same bulk tank I have by the barn.

    I buy un dyed ULSD in bulk and just keep track of the tractor gallons used and every quarter apply for the tax rebate. Pretty simple really.

    I Haven't used 'off road red dye diesel in years. No point really.... and I never run B20 either.

    Doing it is one thing. Getting pinched is another. The fine offsets many. many gallons of cheaper fuel.

    Around here, they just insert a clear hose in your tank, thumb over the end and pull it out. If it has a red hue, then they get serious. I see then at farm auctions and events all the time.

    They (state people) don't always ask permission either. They walk around and check tanks... If you are dirty, then they formally ask but they already know.
  • If you're ever in PA try it at your own risk lol. I have had the state revenue people, the taxman not the walrus, come on construction sites and sample fuel from every oil burner there, and more than once or twice. I knew a guy years ago that paid out over $15K in fines. They say once
    You run it it's almost impossible to get rid of it. I guess they have some way of detecting trace amounts. More to it here than sticking a clear hose in, they bottle up samples and take them to a lab.Its like a piss test for your truck.
