Up to a $25,000 fine if caught on the highway. I think if you can prove how many miles you drove on the red dye on the highway they will just fine you by mile, but if you can't they can fine you up to the 25K. There is undyed farm diesel (all red dye diesel is #1 diesel with red dye signifying no road tax) that is road taxed, but there isn't any savings that route. On road diesel (green) is usually #2 but as the temp drops it gets blended with #1 to prevent gelling. Red is #1 diesel and so is undyed diesel. Farm diesel gives you more power because it is thinner and has more smaller carbon chains.
The red dye is not the same thing we had before the 15ppm. This just has to do with sulfur content and I am pretty sure in 2010 even the off road diesel was switched to 15ppm.
