Fuel Selection (5.7L Gas Engine
)89 Octane, (R+M)/2 Method, Mid-Grade Preferred (87 Octane acceptable).
Fuel Selection (6.7L Diesel Engine
)Use good quality diesel fuel from a reputable supplier in your vehicle.
Federal law requires that you must fuel this vehicle with Ultra Low Sulfur
Highway Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of
Low Sulfur Highway Diesel fuel (500 ppm Sulfur maximum) to avoid
damage to the emissions control system. For most year-round service, No.
2 diesel fuel meeting ASTM specification D-975 Grade S15 will provide
good performance. If the vehicle is exposed to extreme cold (below 20ÉF
or -7ÉC), or is required to operate at colder-than-normal conditions for
prolonged periods, use climatized No. 2 diesel fuel or dilute the No. 2
diesel fuel with 50% No. 1 diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel filters.This vehicle is fully
compatible with biodiesel blends up to 5% biodiesel meeting ASTM
specification D-975.

EMISSION CONTROL SYSTEM MAINTENANCE
The ªScheduledº maintenance services, listed inbold
typein this section (Section 8) must be done at the times
or mileages specified to assure the continued proper
functioning of the emission control system. These, and all
other maintenance services included in this manual,
should be done to provide best vehicle performance and
reliability. More frequent maintenance may be needed for
vehicles in severe operating conditions such as dusty
areas and very short trip driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sion control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part which has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULES Ð 6.7L TURBO
DIESEL
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²Check the engine oil level about 30 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
