What is ULSD and how is it different from Low Sulfur Diesel (LSD)?The United States (U.S.) Environmental Protection Agency (EPA) defines Ultra-Low Sulfur Diesel (ULSD - S15) as a U.S. diesel fuel with a sulfur content not to exceed 15 parts per million (ppm) or 0.0015% by weight. Low Sulfur Diesel (LSD - S500) is defined as a U.S. diesel fuel with a sulfur content not to exceed 500 ppm or 0.05% by weight. The LSD fuel commonly available in North America normally does not exceed 350 ppm sulfur. Both ULSD and LSD should meet the fuel requirements outlined in "ASTM D975-07b".
Why is the sulfur content of diesel fuel in the U.S. reduced to 15 ppm?ULSD is required by U.S. EPA regulations for highway vehicles to ensure that these vehicles will meet emissions standards to improve air quality. In California, other properties of vehicular diesel fuel are also controlled to help reduce smog.
Can I use LSD fuel in model year (MY) 2007 or newer on-highway engines?On-highway diesel engines built in 2007 and later model years (U.S. EPA 2007 certified) must operate with ULSD fuel to comply with U.S. EPA regulations. Using LSD fuel in MY2007 and newer diesel engines powering on-highway vehicles is illegal and punishable with civil penalties. Fuel sulfur above 15 ppm can reduce the efficiency and durability of the engine. The potential impact may include permanent damage to the emissions control systems, reduced fuel economy and more frequent regeneration events. Engine failures that result from improper fuel usage are not Caterpillar factory defects and the cost of repair is not covered by a Caterpillar warranty.
How do I know if I have a MY2007 on-highway engine?Cat MY2007 Low Emission Engines can be identified with the following serial number prefixes:
C15: SDP1-UP
C13: LEE1-UP
C9: C9S1-UP
C7: C7S1-UPNote: The truck chassis model year may or may not correspond to the engine emissions model year. In some cases, a MY2006 emissions engine may power a MY2007 chassis model.The MY2007 engine is identified with specific labels that show the following:
Serial Number
2007 Engine Emissions LabelFuel labels incorporating the words "Ultra-Low Sulfur Diesel fuel" are attached by the truck manufacturer to the on-highway vehicle chassis at the following places:
Near the fuel tank(s) filler neck
Instrument panel (dashboard)
When will ULSD be available in the U.S. for MY2007 on-highway engines?The timeline proposed by the U.S. EPA states that ULSD fuel is expected to be available at most retail locations by 15October 2006.Note: In the U.S., diesel fuel classified as LSD fuel may still be sold at some retail locations outside of California during the 15October 2006 and 1December 2006 time period.
State of AlaskaFuel distributors in urban Alaska will follow the same transition schedule as the distributors in the rest of the U.S. for on-highway diesel fuel.Alaska has received an extension of the on-highway fuel 15 ppm maximum fuel sulfur requirement for rural areas (those areas not served by the Federal Aid Highway System). The 15 ppm maximum sulfur content diesel fuel must be in retail facilities in the
