Red off road / heating oil OR ULSD from pump???

[Fordiesel69]

For my NH Boomer 30 with a mitsubishi indirect injected engine, I have choice to buy off road dyed red which is not supposed to be ULSD. Or I can buy the green ULSD at the pumps. Which will promote better injection pump / injector life? The cleaner burn of the ULSD can be smelled, so I wonder if this helps the engine internals stay cleaner with the expense of shortening the life or the injection components.

Opinions please?

You don't have a choice .
It's all ULSD no matter what anyone calls it!

Unless you're buying marine fuel, the off-road (or Non-road as EPA calls it )diesel is likely the same 15 ppm as the on-road fuel. The EPA has given small refiners til 2014 to convert to ULSD. So buy off road diesel at brand name stations and you'll be okay.

See this chart >> http://www.epa.gov/otaq/fuels/dieselfuels/documents/420b11003.pdf

I wonder if your "splitting hairs". I've heard that the sulpher in the "old diesel" (heating oil) was good for lubricity in the injectors and pump and that an additive is available now for this. There seems to be many fuel related questions out there. For the big fuel user, paying road tax for ULSD could add up. Where a homeowner going thru a few gallons a week during the summer, not so much. And with some of the newer "tier" emission BS you could damage some costly govt. mandated equipment on your machine.
I'm keeping my old stuff (pre emission) and running HH oil! Been doin' it for years.
If you are pre emission, I doubt that you need to worry about engine damage from what used to be std. diesel fuel (#2 fuel oil heating oil):thumbsup:

Yeah with very few exceptions everything out there is now ULSD.

Feed her some Power Service every now and again and don't worry about it.

I could be wrong, but the fuel I get that is dyed red is not ULSD. It smells way stronger, will make you fall flat on the floor should you step in it, and the exhaust smells old skool strong. The green stuff that came in my tractoer when new (dealer was nice to fill it), did not smell anything like the red stuff, especially the exhuast odor.

Perhaps you're getting heating oil instead of diesel...

I would ask the fuel distributor what is is. The new engines & fuel systems are designed to run on ULSD with changes made to Injection pump and injectors to adapt for the loss of lubriction from the sulpher. I don't know what, if any, negative problem might be running higher sulpher fuel in current IT-4 engine that does not have exhaust after treatment, but the sulpher WILL plug up the catalyst reduction on engines with DPF or DEF injection. I would either find out what the off road fuel is or jsut buy the road fuel at local filling station.

I would go to the distributor and see how he handles the HHO and #2 diesel. I would bet they come from the same tank. My 2010 tractor says use ULSD diesel. Refineries have replaced the lubricity of sulfur with an additive so the ULSD is not going to hurt your pump or injectors even on older tractors. I ran my 1984 Yanmar on ULSD and didnt add any additives to the mix and it ran ok for the 4 years I kept it. My brother in law has it now and still cranks and runs as it should. I think that the issue of low lubricity of the ULSD diesel is being played up way too much here on TBN. Other than anti-gel agents for cold weather, you shouldnt have to add anything to the fuel. IF it makes you feel better, put another $10 per 20 gallon tank into an additive. It wont hurt anything other than your wallet.
As for smelling different on green vs red, I suppose that depending on where the fuel was put in, it could have had some anti-gel agents in it or could have been a mixture of #1 and #2 diesel that made it smell different. There should be no difference in smell, taste, feel or performance between red dyed and road diesel.

Or the green has more BIO in it?
