will running off road diesel in a new 09' do any harm?

 

if you get DOT dipped you wallet will be hurting BADLY. and depending on what tank you get it from CAN wipe out your injectors fast and the DPF. 6.7. or any EGR/DPF engines very sensitive to substandard fuel.

Not worth it.

 

I do not think the standards for off road fuel ( home heating oil ) have synced yet with the ultra low standard for road fuel, therefore, the off road stuff is most likely low sulfur, and will kill emission equip on 6.7 motor trucks.

 

I was told by my bulk fuel plant manager that off road is the same as on road just died red for tax reasons. I have ran 100s of gallons of off road fuel through my 08, never could tell the difference. But is it worth it ? Here in NM off road fuel is .30 cheaper then on road diesel but running off road in an on road truck is very expensive and D O T does check pickups.

 

I know that to be true as well. but most guys get their dyed diesel from bulk tanks on farms or especially around here from drilling rigs. and the tanks are dirty, have lots of water in them. and are generally not cleaned regularly.

thats were guys up here run into problems.

 

Great thread on a topic most won't touch. I have asked the question to many and can't seem to get enough info to make the call. In fact off road is dyed "low sulfer". In some cases it will be "ultra low sulfer". Problem is you can't tell if the problems are from the fuel or the common problems that come with these new dpf/egr systems. I would suggest at least an extra filter and trap if you plan on running anything that might be intended for off road. I look forward to hearing the real scoop on "low sulfer" vs "ultra low".

 

The two fuels are processed the same but like it was mentioned earlier, off road is dyed red to make it easily identifiable in a visual inspection. If you get LSD instead of ULSD it will increase the possibility of a DPF problem. If you return the truck to the dealer and they find off road fuel or indications that you have used off road, they can/may/could lesson or void your power train warranty. I'm not saying they will, just that they can.
