MAINTENANCE SPECIFICATIONS
CAUTION
Unapproved fuel can reduce econ-
omy or possibly damage fuel sys-
tem components. Lighter fuels typ-
ically DO NOT have enough lubric-
ity elements in the fuel to properly
lubricate the fuel injection system.
Be sure you follow the fuel rec-
ommendations as indicated in this
section of the manual. Failure to
comply may result in equipment or
property damage.
CAUTION
Using diesel fuels blended with
lubricants may cause damage
to your exhaust aftertreatment
system.
Service intervals for af-
tertreatment systems will be re-
duced. DO NOT use diesel fuel
blended with lubricating oil in en-
gines equipped with an aftertreat-
ment system.
Failure to comply
may result in equipment or prop-
erty damage.
CAUTION
DO NOT use high-sulfur diesel fuel
as it will damage the exhaust af-
tertreatment system. Also, the en-
gine will not meet emission reg-
ulations.
Use only ultra-low-sul-
fur diesel (ULSD) fuel. Failure to
comply may result in equipment or
property damage.
CAUTION
If ultra-low-sulfur diesel fuel is not
used, the engine may not meet
emission regulations, and dam-
age may occur to the exhaust
aftertreatment system. The use of
high-sulfur diesel fuel will damage
the exhaust aftertreatment system
and impact the engine emission.
Ultra-low-sulfur diesel fuel is re-
quired for correct operation of the
aftertreatment system. The engine
has been optimized for use with an
aftertreatment system to meet the
2013 U.S. Environmental Protec-
tion Agency regulations. Failure to
comply may result in equipment or
property damage.
