New Rigs & Red diesel

The fuel itself is the same. It has the same sulfer content, grade, and cetane level. On top of that, a dye is added. It's personal opinion if the dye is a problem or not. I do not like the dye, some don't care.

Regardless, it's a non issue. Non taxed fuel is illegal on road regardless what color it is and you can't run it in an old or new truck anyway.

 

RJF is right and wrong about the fuel differences. On the west coast there is no difference in the fuel except for the dye. Some parts of the midwest and east coast will get high sulfur red fuel. That can't be run in the new trucks as the sulfur content of the fuel will kill the injectors. The kicker is most places won't know if they have high sulfur red or just dyed low sulphur fuel. So to be safe don't run red fuel in a road vehicle, the red dye sticks to every thing it touches.

A former employer is a fuel wholesaler and some of his dyed fuel was high sulphur and some wasn't. Depended where it came from in the pipeline.

red fuel

High sulpher content kills new injectors ? How- Why? I have run some red fuel in my 03 6.0 powerstroke. Is it gonna die?

 

You'll be fine.

 

red fuel

Does this mean I can keep using it- or it will be ok if I stop?The sticker on the tank says -may- contain high sulpher content.wich can damage on road diesels. I only put some in every 3 to 4 tanks.:stir:

 

various fuels and their risks

any sulfur content greater than 15ppm (meaning low and high sulfur ) will hurt 2007 on ( or off ) road diesels that are equipped with particulate filters, or any other downstream emissions equipment. The sulfur content will poison these devices, and make them clog earlier than they normally would.

it's also critical to use CJ4 oils with 2007 engines, as the metallic additives ( sulfur / zinc / phosphorus ) in the older oils will lead to premature clogging of these devices when the oil combusts..

Injectors ( and the upper cylinder area ) are at risk with ULSD and low sulfur, while the high sulfur can cause some different problems ( corrosion ) but premature wear won't be one of them. of course, with sulfur going the way of the dodo, that won't be a refuge much longer.

hope this clears up the confusion.

 

red diesel

My truck is a 2003 -so it should be ok? Thanks for your reply.

 

you don't have the sensitive emissions equipment, so having a high sulfur fuel won't hurt as much as having too little sulfur..

the issue really is, high sulfur ( or low sulfur ) fuel isn't legal, regardless of what sulfur level your truck can mechanically live with, because you are using it in an on road application.

using it won't "hurt" your 03 truck, but you could be risking your fuel suppliers neck if he gets caught selling it to you.. or, if it's dyed and you get caught with it somehow, then you are stuck..

as an aside, dyed or not, sulfur counts are all over the map.. I've had fuel tested that was claimed to be 11ppm, turn out to be 100ppm, and I've seen ULSD sulfur counts be as low as 4ppm..

thing is, all refineries limit their diesel fuel sulfur content to 4-5ppm at their output, or they face EPA shutdown.. this has been happening since june of 2006, and there is no seperating of "this is offroad fuel" or "this is onroad fuel" when they are making it.. everyone gets the same fuel from the rfineries..on top of that, you've got inventories of high sulfur still out there, and you have new fuel picking up sulfur as it goes through the pipeline..

I keep telling people.. the sulfur counts on the pump are just general guidelines.. if you want or need a specific type of diesel fuel, get it tested.. the same outfits that do oil analysis can do fuel testing too.. and don't rely on the supplier spec sheets..I've seen them be wrong as well.. fuel suppliers buy whatever is being sold the cheapest that day, and unless you are testing it, you are just guessing as to what you'll get.
