Getting Help Outside the U.S.
and Canada
Before you export your vehicle to a foreign country,
contact the appropriate foreign embassy or consulate
to make sure local regulations do not prevent you
from registering your vehicle. Officials at the
embassy can also help you decide whether you
should import your vehicle to that country.
Officials at the embassy or consulate can tell you
where to get unleaded fuel. If you cannot get
unleaded fuel or can get only fuel with an
anti-knock index that is lower than your vehicle
needs, contact a district or owner relations office
before you leave the U.S. or Canada.

Use of leaded fuel in your vehicle without a proper
conversion may damage the effectiveness of your
emissions control system and may cause engine
knocking or serious engine damage. Ford Motor
Company is not responsible for any damage that is
caused by use of improper fuel.
You may also have difficulty importing your vehicle
back into the U.S. if you use leaded fuel.
