Deisel owners, have you seen the stickers at the pumps?

[setterguy]

Has anyone noticed the signs saying "2007 and newer vehicles are prohibited from using this , engince damage ect.? Are they changing the emission standards on deisel in 07? Is deisel going to get even higher than it is now? Just wondering if anyone has any insight.

[Valv]

Let me guess, price at $ 3.45/gallon......

sounds like a gimmick to me. The new low sulphur motors ave not hit the market yet.

Anyway, you can run low sulphur in your old diesel, not viceversa.

The new semi's and pickup's are going to use the new ultra low sulfer diesel. It would cause some serious damage in the new ones like Val said.

[LMITOUT]

Yes, the new emission standards are coming and you will not believe the garbage they are going to add to these trucks. I also noticed the stickers a while back and I'm guessing they were required to get them on the pumps by a certain date even though the 2007's weren't out at that time, or even now for that matter. The new Duramax is set to be out early next year and the price will be going up proportionally to the amount of emissions equipment that will be on this truck. That's one of the main reasons why I jumped on a 2006.

A litte more info from Cummins on the ULSD change.

Another questions.....I am curious who all is running additives in their diesels and/or which ones? I am currently running Power Service Diesel Kleen in my 03 Dodge.

Do You Have Questions About The New ULSD Fuel?

This fall Ultra-Low Sulfur Diesel (ULSD) fuel will hit the pumps. Here are some frequently asked questions about the new fuel and what it means for your Cummins-powered Dodge Ram.

What Is ULSD?

ULSD stands for "Ultra-Low Sulfur Diesel." ULSD is a refined diesel fuel that has dramatically lower sulfur content compared to traditional on-highway diesel fuel. Current on-highway diesel is sometimes called "Low Sulfur Diesel" (LSD). The maximum concentration of sulfur allowed in "low sulfur" fuel is 500 parts per million (ppm). This limit was mandated by the government in 1993. For ULSD, the maximum concentration of sulfur allowed is only 15 ppm, a 97% reduction in sulfur content.

The lower sulfur content of ULSD means fewer sulfate emissions. It also enables the use of emissions reduction equipment such as particulate filters and catalytic converters to lower emissions of Particulate Matter (PM) and Oxides of Nitrogen (NOx). These systems, together with Ultra-Low Sulfur Diesel, can reduce emissions of fine particulates by more than 90 percent and emissions of hydrocarbons to nearly undetectable levels.

Why Is The EPA Driving The Introduction Of ULSD?

ULSD was mandated by EPA as part of the 2007-2010 emissions regulations for heavy-duty engines. It is considered a "technology enabler," allowing the use of catalyst-based emission technologies on MY2007 and later heavy-duty engines, as well as on Tier 2-compliant light-duty diesel vehicles. In other words, the 2007 emissions regulations on diesel engines are driving the use of catalyst-based emission control devices, such as diesel particulate filters and NOx adsorbers. These devices are sensitive to sulfur, so the EPA is changing the on-highway diesel fuel regulations to lower the sulfur content in diesel fuel prior to the emissions regulations going into effect.

When Will ULSD Be Available?

The ULSD implementation schedule is as follows:

June 2006: Refinery level and importers.

September 2006: Terminal level (downstream of the refinery/importer, except for retail outlets and wholesale consumers)

October 15, 2006: Retail level (including wholesale consumers)

All major truck stops and over 95% of all on-road diesel fuel retailers are expected to meet the 15-ppm ULSD standard by October 15, 2006, and most locations will only carry ULSD. At locations which carry both LSD and ULSD, the fuel pumps will be clearly labeled.

Because the task of changing all the diesel fuel in the U.S. on-highway distribution system is complex, and there are multiple flexibility provisions in the mandated schedule, it is not possible to predict precisely when ULSD will become available at the retail level for a given location.

ULSD fuel is backwards compatible, and can be used in all engines.

What Can I Expect With Regards To Maintenance And Fuel Economy?

In general, the processing required to reduce sulfur to 15 ppm also reduces the aromatics content and density of diesel fuel, resulting in a slight reduction in energy content (BTU/gal). The expected reduction in energy content is only approximately 1%.

No impact to fuel filter service intervals is expected.

The same water-drain maintenance practices that are currently followed for fuel filters should also be continued.

A new CI-4 engine oil is being introduced, with a new formulation designed specifically to work with ULSD fuel. If you run with a pre-2007 engine oil (such as CH-4) and ULSD fuel, you will have to modify your oil change schedule.
