What are the pros and cons of running off highway diesel in a cummins. Will it eliminate the need for addatives?

Con's. The tax man will take you to jail. :roll: All of our fuel here is ultra low sulfur including heating oil. We used to be able to get the GOOD stuff for off road equipment and heating oil. They actually made it against the law for boats to run the ole good stuff. As far as I know the only difference is the color.

The only way you'll get caught is if you tell people, or you get your tank dipped. I've been driving commercial trucks for six years and only had my tank dipped once, and it was by someone from the IRS if I remember right. In a pickup I've never been checked. Too bad the off road stuff isn't the old high sulfur fuel.

Standard practice here in Maine for the Commercial truck police to stick the tank. A guy in town got busted for it and he had to pay a few thousand to get his truck released. They then went to his yard and tested the rest of his trucks. It cost him more. :D They even sucked a gasser truck once while the driver laughed at them. The cop says " Hey, thats gas not diesel ". He said " Last I knew a gas engine ran on gas ". :D

There are some guys around here that run it in there trucks. I don't don't think I would take that risk. I can't afford the $$$$$$$$ fine. :shock: although it would be nice to avoid the tax man! Maybe I'll start running veggie oil :D

same thing will occur if they find it... unless you paid road use taxes on what you use .

I ran the offroad diesel in a 92 for two weeks and the only difference i noticed was that it smoked alot more than the ultra low sulfur diesel at the pump

There is no diffrence here besides the dye in on and off road fuel. Personaly I like the ULSD as I gained about 1mpg consistently when they switched. Sulfur is abrasive and damaging to fuel systems anyway. It used to be the process required to remove it was what took the lubricity out. As long as the fuel is good quality ULSD is better for your fuel system and engine than High sulfur fuel. The DOT checks truck tanks around here all the time even in parking lots like walmart. They have found it to be a good way to raise the funding they need to keep their jobs as the tax incomes have decreased from the slowing economy. Personaly I don't think the $10,000 donation can ever be made up in the 20cent a gallon diffrence.

Price differences vary state to state dependent upon how greedy your state is. PA is very greedy. The difference in price is generally in the 50 - 60 cent range here. This has been quite consistent during our governor's two terms.

Its over 50 cents a gallon tax here in Maine. We are a small company and our fuel bill is several thousand a year. We might be able to save a few thousand a year if we did not pay road tax. Getting caught once would cost more then the savings of 2 or 3 years. Not really worth it. We have 2 bulk tanks. 1 for off road and 1 for on road. Just put over a hundred gallons in one truck today. :roll: When fuel was sky high we could burn close to a hundred gallons per day ( on a long day ) and with 2 trucks hauling the bill would be over a grand. :evil:

Works out slick for me, I have a 2nd tank under the rear of my bed, the opening is hidden behind LR wheelwell. I fill my stock tank with clear diesel and rarely use it and run off my 2nd tank filled with the red go go juice. Dbout I'd ever get my tanks dipped in a pickup, if I was goin to I guess I'd have to play really stupid then.

No offense but its people like you that make the rest of us pay. Not only that but since you posted on a public place, all they have to do is type diesel forum in the google bar and find this place, subpoena to get a IP address and get your info. Or they get rid of the off highway advantage and make everyone pay taxes which then require the companies to make everything more expensive for the rest of us.

Same thing with people and illegal aliens on welfare....

Off the soap box.

It's hard for me to imagine how anyone could get better mileage with ULSD since the process of removing the sulphur also leaves around a 1% less energy dense fuel with lower aromatic content. It also reduced lubricity to the point where they had to come up with a new lubricity standard (ASTM D975), which basically amounts to the suppliers blending their own lube adds at low level terminal locations.

ULSD is just another angle on the government's overall stupid energy strategy, right along with ethanol, wind, yad, yada. Of course all great ideas that didn't get thought all the way through before billions were spent and the damage done. Damage to injector pumps and injectors in our case.

Y'all go ahead and trust Shell, XOM, BP etc. to make sure they add plenty of Powerservice to your fuel before they top off the tanker truck on the way to your location now! :P
