High Sulfur Fuel

[dullpain]

I got my helmet on , and my Kevlar vest !! Tell me what Hi Sulfur Fuel will do to a 6. 7 if anything .

 

[EMAC2]

do you have the stock exhaust system?

Plug the particulate filter in the exhaust. Plug the EGR system components. That's just off the top of my head for starters.

In real simple terms, the same thing leaded gasoline will do to a gasoline engine with catalytic converter. Over time it will build up on your 3 stage exhaust cleaning system. The trucks cleaning system (regen cycle) will not be able to remove it (the sulpher), the exhaust system will plug, the check engine will come on, the ecm will go into "limp mode", and eventually will not start. At this point you remove the DPF and do a "delete",or take the DPF to a company which specializes in cleaning DPFs for the retrofitted large engines or purchase a new DPF, reinstall and take to dealer to reset the ECM. As far as damage to the engine itself, none. This is a very basic and simple explanation. And at the end it voids your engine warranty (questionable).

Where can you buy anything but ULSD? The off-road red dyed diesel fuel I purchase in bulk for my farm tractor is also ULSD with red dye added.

Waiting to hear the answer to this one MY OWN DAMN SELF!!!! Maybe south of San Diego Mexico???

My Co-Op sells Hi sulfur diesel. Thanks to all for the replies , I get it . As I thought bad for the Govt. supplied emissions equipment

Just for kicks I looked up a little info. I DONT THINK I WANT TO RUN THAT ON THE ROAD!!! could be VERY BIG BUCK FINE.







United States



As of September 2007, most on-highway diesel fuel sold at retail locations in the United States is ULSD. [8]



Ultra-low-sulfur diesel fuel was proposed by EPA as a new standard for the sulfur content in on-road diesel fuel sold in the United States since October 15, 2006, except for rural Alaska who transferred in 2010. California has required it since September 1, 2006. This new regulation applies to all diesel fuel, diesel fuel additives and distillate fuels blended with diesel for on-road use, such as kerosene, however, it does not yet apply to railroad locomotives, marine, or off road uses. Since December 1, 2010, all highway diesel fuel have been ULSD. Non-road diesel fuel was required to move to 500 ppm sulfur in 2007, and further to ULSD in 2010. Railroad locomotive and marine diesel fuel also moved to 500 ppm sulfur in 2007, and will change to ULSD in 2012. There are exemptions for small refiners of non-road, locomotive and marine diesel fuel that allow for 500 ppm diesel to remain in the system until 2014. After December 1, 2014 all highway, non-road, locomotive and marine diesel fuel produced and imported will be ULSD.



The EPA mandated the use of ULSD fuel in model year 2007 and newer highway diesel fuel engines equipped with advanced emission control systems that require the new fuel. These advanced emission control technologies will be required for marine diesel engines in 2014 and for locomotives in 2015.



The allowable sulfur content for ULSD (15 ppm) is much lower than the previous U. S. on-highway standard for low sulfur diesel (LSD, 500 ppm) which allows advanced emission control systems to be fitted that would otherwise be poisoned by these compounds. These systems can greatly reduce emissions of oxides of nitrogen and particulate matter.

so my 06 is OK with high sulfur diesel???

Are you sure? The pump may have an old out of date sticker on it. Most late model off road diesel engines over about 50-hp now are equipped with some form of EGR, and/or NOX catalyst with or without the use of DEF, and have a DPF which requires ULSD fuel.

It depends on what you call "high sulphur". Diesel fuel was originally 5000 PPM sulphur, but that ended in 1994 when particulate standards were reduced and 500 PPM fuel became standard. 500 PPM should work in your '06, as that's what was available when the truck was made.



I don't see any advantage to using it, as any lubricating qualities the fuel had was removed in the transition from 5000 to 500 PPM.

Here is the EPA time line on when ULSD fuel is to be available for sale and when the refineries need to switch over to making the ULSD fuel.
