What is purple fuel? I know what red fuel is, its off road tax free diesel that is no different than normal pump diesel except for the dye.

Ultra-low sulfur highway diesel fuel (15 ppm sulfur maximum) required fuel for 2011. If you have been running it for one year, then it must be ultra low sulfur diesel fuel. If it wasn't your check engine light would have turned on along time ago. The DPF would have been plugged up along with the EGR and the EGR cooler. If bio fuel in excess of 5% is not recomended and excessive oil dilution and severe internal engine wear will result. Have the fuel tested by a fuel lab if in doubt, or place a sample in freezer and check for rapid gelling compared to a good sample of Ultra-low diesel fuel.

Man first thought was AvGas!!!

That would give some interesting results.

You should be fine, not a whole lot of LSD lurking around nowadays.

jodrt, it won't hurt your truck as even the dyed diesel is ULSD now days, but it can hurt your wallet if the DOT guys decide to dip your tank. It changed the same time that the road diesel (road tax included in price) did and I've been adding lube treatment to it for my tractors ever since.
