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.

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.

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.

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.

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.

K1 kerosene is a low-sulfur kerosene that is made for use in space heaters, lamps, etc. - and not for use in vehicles or generators. It is also not taxed so would be illegal to use in "on-road" vehicles. Lower lubricity is likely as the viscosity decreases. While this may not cause catastrophic instant damage, it could cause long-term wear of pumps, etc. Four semi-annual surveys for years 1990-1992 showed national averages as such for viscosity (represented in milliPascal-seconds (mPa .

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.

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.

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.

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.

About 1% (one percent) of what other vendors call low bandwidth, generally in the 10's of kilobits per second instead of megabits per second.

NO! Any mixture above 20% veggie oil is putting your engine and injectors at great risk. The risk is even more serious in colder climates. In addition, to truly get veggie oil to mix with diesel or kerosene, they actually need to be heated anyway.

No. The most stringent government standards for indoor ozone are those of the Food and Drug Administration for indoor medical devices, which specify that ozone output be no more than .05 ppm. In a closed test room with the Blueair 501 in operation, probes measured ozone levels at .003 ppm-a tiny fraction of the amount deemed hazardous to human health. Our design safeguards against excessive ozone production, and then removes ambient ozone particles from the air.
