I use to have a 2000 dodge cummins for the last years i ran straight home heating oil mixed with cetane never had a problem till i sold it and my buddy did the same in his 01 excursion 7.3 never had a problem. Today at the beach i was talking to a guy and he said i cant run it in a 6.0 besides the fact its"illigal" the motor can not handle it but couldnt explain.ive had my 03 6.0 for mouths now and have been running oil with no problems now I need you guys to fill me in on what I'm doing wrong.in ny the average is 4.25 a gallon and home heating oil is at 3.05a gallon because my buddy with the excusion works there and I always fill up 350 gallons I've always known the two fuels to be seperated just by difrent dies and te chemical cetane please let me know

 

do they have btu ratings that are the same. also is one thinker then the other.
being in texas are home heating oil is the sun. never seen the stuff.

 

You can run anything through a common rail injector, the pin and plunger type needs lubrication. A diesel will burn almost anything you can feed it but our injectors are a little pricey, so is it worth the risk?

The other answer is pretty straight forward, NO road tax is why the home heating oil is cheaper. Get caught and you could face a $100 per gallon fine, so if you have a 32 gallon tank do the math.

 

Minus the red dye its the same fuel, same as off-road #2 fuel, I would continue to use a cetane improver and watch out for the tax man.

 

Heating oil has a higher sulfur content than the ULSD that the government says we have to run in our 2007 or newer vehicles. Heating oil is also dirtier than the diesel refined for our vehicles. This might force sooner fuel filter change requirements. If I had the access to heating oil that you do, I would be using it in my truck.

 

Home heating fuel/offroad diesel, and diesel all come out of the same pipe when it's being refined. The red dye that's added makes all the difference, and I would bet that cetane chemical's are also added for fuels that are going to be used in diesel engines. P.S. I wouldn't run your mouth too much if you burn untaxed fuels.

 

I was thinking the same thing, atleast just ask the question, don't need to tell us your running it.

 

Also the fuel thats prepared for diesel engines goes through another process to remove almost all the sulfur, where the heating fuels can have a sulfur content anywhere between 500-2000 PPM sulfur. Many states in the mid atlantic and northeast set there own EPA requirements on sulfur content, but all of them are legislating 15PPM within the next 5 years.

 

Im not to worried about the"tax man" i run 3 big trucks and i would never run the red die in them but i aslo go into jersey daily and the fuel is 70 cents cheaper per gallon not worth the risk i doubt they would come after my pick up

 

Don't be too confident about not being stopped for a check. A friend of mine about 4 years ago was heading up the northeast extension of the Pa. turnpike. He pulled off at a service center so his wife could use the rest rooms, and when he was ready to leave and get back on the tpk. his Dodge pickup was waived down for a check. I have had diesel pickup's since 1989 and have never been stopped, but I would never take the chance myself. I think you run a much higher chance of being caught for running untaxed fuel, not by being stopped, but telling too many people how you save money. Eventually you tell the person who will come forward and report you as a tax cheat. Is that person a snitch, or is he doing a responsible duty?
