Gasoline for Cleaner Air
Gasolines with detergent additives
help to prevent deposits from
forming in your engine. This helps to
keep the engine in tune and the
emission control system working
properly. These additives as well as
gasoline blends containing oxygen,
such as MTBE or alcohol, promote
cleaner air. This is important in
locations that have high carbon
monoxide and ozone levels.
Fuels in Foreign
Countries
Foreign Operation
If you plan on driving in another
country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you
use even one tankful, your emission
controls won't work well or at all.
With continuous use, spark plugs
can get fouled, the exhaust system
can corrode, and your engine oil
can deteriorate quickly. Your
vehicle's oxygen sensor will be
damaged. All of that means costly
repairs that would not be covered by
your warranty.
To check on fuel availability, ask an
auto club, or contact a major oil
company that does business in the
country where you'll be driving.
Fuel for Diesel Engines
Diesel Fuel Requirement and
Fuel System
Fuel Requirements
Use of fuels other than ultra
low-sulfur fuel may not conform to
emission regulations.
The fuel supply pump, injector or
other parts of the fuel system and
engine can be damaged if you use
any fuel or fuel additive other than
those specifically recommended by
the dealer.
To help avoid fuel system or engine
damage, pay attention to the
following:
.
Some service stations mix used
engine oil with diesel fuel. Some
manufacturers of large diesel
engines allow this; however, for
your diesel engine, do not use
diesel fuel which has been
contaminated with engine oil.
Besides causing engine
damage, such fuel can also
affect emission control. Before
using any diesel fuel, check with
the service station operator to
see if the fuel has been mixed
with engine oil.
.
Do not use any fuel additive
(other than as recommended
under "Biocides" in
). At the time
this manual was printed, no
other fuel additive was
recommended. (See your
authorized dealer to find out if
this has changed.)
.
Take care not to run out of diesel
fuel. If you do run out of fuel,
you may need to bleed air out of
the supply pump to re-start the
engine after fuel has been filled.
Your vehicle is designed to use
either Number 1-D or Number 2-D
diesel fuel. However, for better fuel
economy, use Number 2-D diesel
