Hi,

My name is Fabio Aguilar.

Buy a Dodge RAM 6.7L Cummins Turbo Diesel in 2007 with the Ultra Low Sulfur Diesel system.

But the car was exported to Honduras, where there are only normal diesel.

How can I do to make the vehicle has no problems?

There any special additive to lower your normal sulfur diesel?

There any kit to convert car to use regular diesel?

You can remove this option of my car?

Thank you


Fabio

Hi,

What I need to know is if going to trip to Mexico or Central America and these countries not exist ULSD would happen with the engine? There is some additive or any kit that you can use regular diesel in my car?

Thank you and I will your response

ASAP

Putting Low Sulfur Diesel in an engine designed to run only ULSD can result in costly emissions control system damage.

No other info at this point.

Thanks for your reply, but I am not satisfied.

That tells me or sends me to read and knew it, I need to know if there are any chemical or engine kit suitable for use normal diesel.

I understand, I haven't heard back from the folks I contacted that should know, so I at least passed that site along knowing you were very antsy to get an answer. I think it did elude to the chance wasn't likely which wouldn't satify me either. Such is life.

I will say this however. In the US, if you come up with away to avoid compliance with emission standards, you are in deep doo-doo. No one is going to offer a product to increase the emissions like your are looking for.

IF you want to do this you are going to need to completley remove anything related to this system change which will likely include the computer. Now the computer on an older one is going to have parameters for other systems that will not be compatible with the newer truck you have.

LAtest that I have heard, sent to my email:

I'll need to do some more research on this. However, I understand that routine use of low sulfur diesel will harm the emission control system and will probably lead to filter clogging. Since this vehicle was exported, there may be a way to deal with this problem. EPA has issued regulations that delay the ultra low sulfur diesel requirements in Alaska due to fuel availability. I'll go over that material to see if there is an answer. Otherwise, I may need to refer you to the proper person at EPA's motor vehicle laboratory.

Regards,

Dave

Fabio, this was the latest contact with Dave, I am still researching on this one to see what more I can find out.
I have a friend that works for cummins in the R and D dept. That may shed more light on this.

Paul,

I have done a little more research on the issue of running a vehicle built for ULSD on low sulfur diesel fuel. Probably the best answer I could find is in EPA's regulatory impact analysis for the 2007 and later model year vehicles. In the regulation documents implementing both the emission standards and the ULSD fuel requirements, the EPA responded to the State of Alaska's request for a temporary exemption in rural areas from the ULSD requirement:

The use of high-sulfur (>500 ppm) diesel fuel may cause plugging or increased particulate

sulfate emissions in diesel vehicles equipped with trap systems or oxidation catalysts, and could

impair the ability of oxidation catalysts to reduce hydrocarbons (HC) and CO exhaust emissions.

However, any increase in sulfate particulate emissions would likely have only a minor effect on

ambient PM10 levels in Alaska since current diesel motor vehicle contributions to PM10 emissions

are minimal.

The bottom line is that high sulfur fuel would cause higher emissions and might clog the emission control system. That's all I can find. The contact at EPA for more detailed information is:

Charles Schenk 734-214-4700, schenk. Charles@epa. Gov

I hope this helps.

This came from Charles Schenk:

Paul,
There are a couple potential issues that could arise that are best
answered by the engine manufacturer. The degree of issue(s) depends on
the fuel sulfur level. The higher the sulfur level the less effective
the PM filter will become and it may eventually have problems
regenerating properly. Another issue is EGR system corrosion. Some EGR
systems are more sensitive to sulfur than others. The engine
manufacturer should be able to provide more specific information on how
their systems will be effected by sulfur levels that are higher than the
design target.
