While this is a SLIGHT thread drift, for those who have those bullet kero heaters, you can burn the #1 diesel in them. I burn it in my reddy heater without any problems.
As has been said, off road diesel is the same as ULSD just has the red dye to identify it. I know of several people who run it all the time in their 2006/07 trucks. I also know several of them HAVE gotten stopped in checks and fined big-time. A couple years ago the fine was only $500, it was low at that time to give everyone a break and let them know it's on-road use would not be tollerated any longer, today the fine is up to the DOT max amount of $2,500. I'd reallythink twice about using it on-road,not worth getting caught, and I do think we will see more and more DOT checkpoints specifically for checking our trucks. Last year in Texas there were several people reporting being 'dipped' and 'fined' and the DOT was on some small back roads. The horse/rodeo people all have been complaining about this happening at their events as well.
