2003 FORD E SERIES fuel

•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
•Have the items listed in your scheduled maintenance guide performed
according to the specified schedule.
The scheduled maintenance items listed in the scheduled maintenance
guide are essential to the life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting

tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
•Use only SAE Class S chains.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.

1Add the coolant type originally equipped in your vehicle.2If your vehicle’s rear axle is filled with a synthetic rear axle lubricant it
is considered lubricated for life. These lubricants do not need to be
checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle lubricant should
be changed any time the rear axle has been submerged in water.
Fill 6 mm to 14 mm (1/4 inch to 9/16 inch) below bottom of fill hole.
Add 118 ml (4 oz.) of Additive Friction Modifier XL-3 or equivalent
meeting Ford specification EST-M2C118–A, for complete refill of 8.8 inch
and 9.75 inch Traction-Lok axles.
3Fill Dana rear axles to 6 mm to 19 mm (1/4 inch to 3/4 inch) below
bottom of fill hole.
4Visteon Traction-Lok axles require 118 ml (4 oz.) of Additive Friction
Modifier XL—3 or equivalent meeting Ford specification EST-M2C118–A.
Dana limited-slip axles (E250/350/450/550) require 237ml (8 oz.) of
Additive Friction Modifier C8AZ—19B546–A or equivalent meeting Ford
specification EST-M2C118-A.
5Optional fuel tank 208L (55 gallon).
6Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to your scheduled maintenance guide to determine
the correct service interval.
