His answer you get a ticket and you have to prove it's not the off road fuel dye. The fine is very substantial per gallon of capacity. I hope this helps
I did my own fuel filter change two years ago for the first time. I used ATF to prime the filters, as suggested by another forum member. 3000 miles later and the clear bowl on my water separator was still red. I thought about the red off-road fuel issue and decided it wasn't a worth the risk, so I added a Cat priming pump and now prime the filters with diesel fuel from the RV's fuel tank. For what it's worth, I noticed no change in performance with the added ATF.
Worried about the low lubricity of today's diesel fuel, I use a fuel additive called Ethos. Ethos is marketed as a fuel saving additive but I use it for its lubricity properties. I sold it for a coupe of years, but stopped when I couldn't make any money at it....it was just too expensive. I am using what inventory I have left and plan to switch to Stanadyne when my Ethos is gone.
Just my two cents...
