Just happened to be outside yesterday when my heating oil was delivered. I talked to the driver and asked him the difference. He said "Taxes and this". He then went to the cab of the truck and pulled out a little bottle of dye and squirted into my tank. 1 oz per 1000 gallons. Everything he carries on that truck is #2 USLD. They very rarely dye the truck because they deliver different customers and it is a pain to rinse, so they dye on site.
I have gotten several loads of heating oil that WERE NOT dyed.
