There is now a third version of diesel oil that suppliers sell by me - after old stocks are used up. Some exceptions allowed if there are any shortages. The new off-road is not ulta-low sulfur yet, but is dyed a new color (not red). I've read through the legal documents and it makes my head spin. So, I just go by what I'm told when I call to order the stuff. I was told that the dyed red fuel is no longer legal in New York in any engine - i.e. used for heat only. The "off road and farm" is dyed a new color, taxed a little different, but in most cases is NOT ultra low sulfur - yet.
Here's some docs. If it makes sense to you - you're smarter - or at least more patient - then me.
