No, ULSD sold in California and elsewhere is 15ppm, even better than the 50ppm European standard. It is as clear as drinking water. Even Jet-A has a slight straw color. I remember the old muddy-looking diesel.

500ppm hasn't been around for a few years. It is high sulfur fuel.

Here is an excellent article from exxon on your question.

You can get Off road diesel if you had a station around you that carried it. The EPA
mandates that it also had the 15ppm limit by 2010. It was at 3000ppm and it has to
go all the way to 15!! OF course if you get pulled for running it by DOT thety will
give you a ticket for not paying your road fuel tax!!

The suppliers I have talked to around here said 'everything' they have is 15ppm (max). They said it generally runs around 5-7ppm and even if I bought 'offroad' diesel it would still be 15ppm max.

I guess it is easier to just carry one fuel and dye it for off road or leave it clear for on road as opposed to keeping two different fuels based on sulfur content.
