Have you ever had your pick/up checked?? How do they stick the tank exactally? Sorry for the dumb question.
I've heard that also but don't know how it could be true. Seems like the soot from your very first tank of fuel would be in the tailpipe as well as the very last unless you cleaned it out. What if you had been running red offroad several fill ups earlier. After all it is legal to run red fuel as long as you don't go on a public road.I have heard the chemical in the dye that makes the fuel red can be detected by getting a soot sample from the tailpipe.
