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.

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.

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.

Under the terms of the Oct. 4 highway diesel sulfur waiver, refiners are allowed to distribute high sulfur diesel fuel through Oct. 25. This high-sulfur diesel fuel will remain in the distribution system after Oct. 25, but parties upstream of the retail level, including terminals, must comply with the highway diesel sulfur standard no later than on Dec. 10. Retail stations will be able to transition their storage tanks to comply with the highway diesel fuel standard after Dec. 10.

Allowing fuel with higher sulfur content for a limited period will have little, if any, adverse impact on diesel engines. However, prolonged exposure to higher sulfur fuel would very likely have adverse impacts on engine durability. Absent a waiver, EPA regulations require that high-sulfur diesel fuel must be dyed red, otherwise it is subject to the 500 ppm sulfur standard for highway diesel fuel.

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.

No. You do not pay the diesel fuel tax when purchasing dyed diesel fuel. However, dyed diesel fuel should only be used to operate vehicles or equipment off-highway. You will be subject to the tax and a penalty if you operate a motor vehicle on a highway in California with dyed diesel fuel in the supply tank. Yes.

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 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.

You may submit your refund claim and registration application at the same time, though the registration process may slow the handling of the claim. In addition, you will be asked to submit a completed Diesel Questionnaire.

There is no difference between fuel (heating) oil and off road diesel. However, road diesel has lower sulfur and is clear. Heating Oil and off road are dyed.

There is no definition of premium fuel, so the term eally means nothing and is over used by suppliers. For a descrition of the characteristics proposed for "premium diesel" see this Cheveron bulletin. Cummins says that fuel additives are not needed in their engines.

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.

Emissions results do vary between engines and test equipment, but in our tests on an early 80's VW turbodiesel, opacity (which is used as an indicator of particulate emissions) was reduced by about 50%, compared to premium diesel fuel. Other EPA regulated emissions were about the same for all the fuels tested. Power was equal to premium diesel that test. We find no difference power while driving, between diesel and SVO/WVO, as long as the filter is clean and the SVO is heated.

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.

Well, you could mix it yourself (as mentioned earlier), but there is a company in California called Aero Dyne who sells pre mixed diesel in small, or large quantities for a very reasonable price--and how I wish I could buy their fuel here :-(

Yes, The EPA has finalized similarly stringent standards for non-road diesel fuel that will be phased in over several years. In California, there is no distinction between on-highway and off-highway diesel fuel. The 2006 California diesel fuel regulation will cover off-highway diesel as well.
