[QUOTE="Campground Cattle, post: 355176, member: 195"] Diesel fuel must meet minimum lubricity requirements to protect components such as fuel injector pumps and fuel injectors against premature wear. Much of today's low-sulfur diesel (LSD) fuel stock has natural lubricity and does not need lubricity improvers. But tougher ultra-low-sulfur (ULSD) requirements, mandated by the U.S. EPA for #1 and #2 diesel fuel, take effect in June 2006. As refiners increase the severity of hydrotreating to cut sulfur content, most of the natural lubricity is removed. The ASTM D-6079 diesel lubricity specification balances input from engine makers, standards officials, and fuels producers. It says that a "wear scar" no larger that 520 microns in diameter should result from a standardized wear test Experts estimate that as much as 50 percent of today's LSD pool will need a lubricity improver to meet the 520-micron specification and that up to 75 percent of the diesel pool could require treatment as refiners convert to ULSD production in 2006 and beyond.
