Use of Biodiesel for VOLVO US2010 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 been 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, 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.
Customers will need to utilize oil sampling to establish appropriate drain interval(s)
for their application(s).
Fuel Storage
If fuel is stored on site:
•
Keep storage tank covered to prevent water entry.
•
DO NOT use a tank made of galvanized metal or any galvanized piping for diesel
oil storage. Diesel will react with the zinc, forming solids that can clog fuel filters
and cause engine damage.
•
Fuel stored for a long time may oxidize and form solids, causing filtering problems.
•
Keep the area around the fill cap clean. Tilt the tank slightly toward the drain plug
area so water and sediment can be easily drained.
Generally, fuel contamination occurs as the result of improper fuel handling. The most
common types of contamination are water, dirt and microbial growth (black slime).
The formation of varnishes and gums resulting from poor fuel stability or long storage
(stale fuel) also affects fuel quality. The best treatment for contamination is prevention
by maintaining a clean storage system and choosing a reputable fuel supplier.
