In the 15 years I have lived in Alberta, I have seen only one road check for purple fuel - out on some back road near a small farming town. This dyed fuel is legal for all off road uses: tractors, stoves, construction equipment, whatever. If you mostly drive in the city you can probably get away with running dyed fuel. The fines are not that high if you drive alot of miles and don't get caught very often. And as long as your neighbors don't tattle on you for filling your truck from your tank... In Alberta most people heat with natural gas so there are not very many oil tanks, so if you had one it might raise some suspicion. The dye in the fuel also colors your fuel filter and the inside of your tank so even if you currently run clean diesel but used dyed, and someone checked your filter... Busted!
My father used to haul fuel, and he told me that the only difference between stove oil and the diesel you buy at the gas station is a little bottle of concentrated dye. The diesel comes out of the same tank at the bulk plant. He said that sometimes they don't even dye the stuff.
And jet fuel? You thought that low sulfur diesel was dry, try some of that stuff. Yeah, sure it runs good, but it will really wear your moving parts that rely on fuel for lubrication. Cold climate operators that use this fuel regularly use specially hardened or modified fuel pumps to stand up to the lack of lube.
