6 INTRODUCTION B5 Approval For Volvo US 10 Certified Products Volvo engines are certified to comply with U.S. EPA and California emissions standards based upon the use of test fuels with specifications established by these regulatory agencies. Alternative fuels, including biodiesel, that are not substantially similar to the required test fuels may adversely affect engine emissions compliance and may impact the performance of certain emissions aftertreatment components.
As a result, Volvo does not warrant the engine will conform to applicable Federal or California emissions limits when operated on, or having operated on, biodiesel or other alternative fuels that are not substantially similar to specified test fuels used for certification. The use of biodiesel up to a maximum of 20% (B20) in and of itself, will not affect the manufacturer’s mechanical warranty as to engine or emissions system related components except as limited below with respect to aftertreatment components, provided the bio fuel used in the blend conforms to ASTM D6751, and B1 to B5 blends conform to ASTM D975, and B6 to B20 blends conform to ASTM D7467.
Failures of certain emissions aftertreatment components, specifically SCR, DPF and NOx sensors will not be warranted if the failure can be attributed to operation on biodiesel blends from 6 to 20% (B6 to B20) even if the biofuel used in the blend B6 to B20 conforms to ASTM D7467 or any related standard. CAUTION Diesel-powered engines for heavy-duty trucks built on or after January 1, 2010 are designed to operate only with Ultra Low Sulfur Diesel (ULSD) fuel. Improper fuel use will reduce the efficiency and durability of engines, permanently damage advanced emissions control systems, reduce fuel economy and possibly prevent the vehicles from running at all.
Manufacturer warranties will be voided by improper fuel use. Additionally, burning Low Sulfur Diesel fuel (instead of ULSD fuel) in 2007 and later model year diesel-powered cars, trucks and buses is illegal and punishable with civil penalties. CAUTION Ultra Low Sulfur Diesel (ULSD) fuel with a maximum sulfur content of 15 ppm must be used in order to meet Euro4 engine emission requirements. Using otherwise approved diesel fuels with a maximum sulfur content greater than 500 ppm may shorten engine life and void the engine warranty.
