Maintenance and Specifications
Number 1-D or winter blend number 2-D fuel is recommended at
temperatures below 20°F (-7°C) (see Cold weather operation in the
Driving chapter. Diesel fuel containing no more than 5% biodiesel may
be used. Biodiesel fuel is a product that has been converted from
renewable fuel sources, including vegetable oil, animal fat and cooking
oil. Raw or refined vegetable oil, animal fat, cooking oil or recycled
greases should not be used.
Since it is normal for a small amount of unburned fuel to enter the
crankcase and mix with the engine oil, the use of biodiesel requires that
the engine oil and filter be changed more often. Refer to the Exceptions
section of the Scheduled Maintenance Guide chapter for more
information.
Do not use home heating oil or any diesel fuel not intended for
highway use. Red dye is used to identify fuels intended for
agricultural and non-highway use. Damage to the fuel injection
system, engine and exhaust catalyst can occur if an improper fuel
is used. Do not add gasoline, gasohol or alcohol to diesel fuel.
This practice creates a serious fire hazard and engine
performance problems.
NOTE: Use of any fuel other than those recommended may cause
powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.
WARNING: Using low sulfur (16-500 ppm) or high sulfur
(greater than 500 ppm) diesel fuel in a diesel engine designed to
use only Ultra Low Sulfur Diesel fuel increases the likelihood of engine
oil dilution with fuel which may lead to major engine damage.
WARNING: Using low sulfur (16-500 ppm) or high sulfur
(greater than 500 ppm) diesel fuel in a diesel engine designed to
use only Ultra Low Sulfur Diesel fuel will cause certain emission
components to malfunction which may also cause the Service Engine
