The US government has federally mandated conventional diesel (or #2 diesel fuel) to become Ultra Low Sulfur Diesel (ULSD) fuel for all on-road applications as of September 15th, 2006. California has gone even further, mandating ULSD fuel for both on- and off-road applications as of September 1, 2006. The US consumer perception that diesel fuel is dirty is based on older diesel standards that are now being revised. Europe implemented ULSD over 15 years ago.

ULSD is diesel fuel with reduced sulfur content. Sulfur compounds are one of the reasons that burning diesel fuel creates air pollution. ULSD has less than 10 percent of the sulfur content when compared to standard diesel fuel. ULSD has 15 parts per million (ppm) sulfur, compared to regular diesel fuel which may have from 150 to 500 ppm. Using ULSD will not harm or change the operation of diesel engines. Due to recent changes in U.S.

Diesel Fuel Supplement +Cetane Boost is the product of choice during the winter months due to its superior antigel formulation. Diesel Kleen +Cetane Boost is to be used in the non-winter months for peak engine performance (no antigel component). Both of these products contain the Power Service proprietary Slickdiesel? lubricator that provides maximum lubricity protection to pumps and injectors against wear caused by Low or Ultra Low Sulfur Diesel (ULSD) fuel.

Yes. EnviroFuels DFC is an excellent choice to use with LSD and ULSD fuels. ULSD fuel is now required for use in highway diesel engines, while it is not currently required for non-highway engines. However, non-highway engines are already affected and receiving ULSD fuel in the diesel fuel supply system.

Because of the harmful effects that diesel fuel emissions can have on human health and the environment, the EPA has imposed a new rule requiring cleaner diesel fuel to be sold by September 2006 for use in large diesel trucks and buses.

ULSD fuel costs more to refine and distribute than Low Sulfur Diesel fuel. No one can predict with certainty the price of ULSD fuel at the pump. Many factors affect the consumer price of fuels, including the price of crude oil on the global market, geopolitical, weather, transportation and economic events, as well as supply and demand. Visit the Energy Information Administration web site for more information on fuel prices.

Ultra-low sulfur diesel fuel (ULSD) is diesel fuel that contains no more than 15 parts per million of sulfur. Because sulfur clogs pollution control devices known as particulate matter filters or particulate traps, EPA is requiring that ULSD be available nationwide beginning in 2006. This cleaner diesel fuel will be available before the new trucks and buses that meet EPA's 2007 emisson standards debut on our nation's roadways.

When low sulfur diesel fuels were first introduced in some markets back in the 1990s, there was a rash of fuel injector O-ring failures causing fuel system leaks. The failures were limited to older vehicles and the problems have not recurred. The recent introduction of ULSD has not proven problematic.

Yes, owners of 2006 and earlier model year diesel-powered engines and vehicles may use either ULSD or Low Sulfur Diesel fuel, but ULSD is clearly better for the environment.

The 80% production/import requirement applies to all highway diesel fuel (No. 1 plus No. 2). EPA requirements do not stipulate the percentages of No. 1 and No. 2 that must be produced or imported. Some refiners have told the EPA that they plan to produce Ultra Low Sulfur Kerosene (ULSK) for wintertime blending.

Low-sulfur coal is generally found in the southern half of the State. Contact our Service Section staff with your precise location for more information.

Owners of 2007 and later model year diesel-powered highway vehicles must refuel only with ULSD fuel.* Owners of 2006 and earlier model year diesel-powered engines and vehicles may use ULSD or Low Sulfur Diesel fuel during the transition period. Only ULSD fuel will be available for highway use starting on December 1, 2010.

Ultra Low sulfur diesel fuels (less than 15 ppm) are required by federal regulations for 2007 model year highway vehicles to ensure that these vehicles will meet emissions standards to improve the quality of the air we breathe. In California, other properties of vehicular diesel fuel are also controlled to help reduce smog.

Just as your radio tunes in to different frequencies to hear different channels, RFID tags and readers have to be tuned to the same frequency to communicate. RFID systems use many different frequencies, but generally the most common are low-frequency (around 125 KHz), high-frequency (13.56 MHz) and ultra-high-frequency or UHF (860-960 MHz). Microwave (2.45 GHz) is also used in some applications.

No. At present the EPA requires only 80% of the highway diesel fuel manufactured in the U.S. to be ULSD. Consumers may still find some LSD at services stations and truck stops until December 1, 2010 when EPA regulations will require all highway diesel fuel to be ULSD.

Some of the sulfur compounds naturally occurring in diesel fuel provide some wear protection or lubricity. To compensate for the sulfur removal in ULSD Exxon branded diesel fuel is treated with additives to improve lubricity. Customers can be confident in choosing exxon because our branded ULSD fuel meets ASTM D 975 diesel fuel specifications, which provide standards for lubricity, cetane number and other performance characteristics.

ULSD: Ultra Low Sulfur Diesel. This fuel is now available across the country. 2007 and newer model diesel motorhomes are required to use it for the main propulsion engine. Cummins Onan generators will function properly on ULSD with no change to performance or maintenance intervals.
