Fuels in Foreign Countries
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 wouldn’t
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.
You can also write us at the following
address for advice. Just tell
us where
you’re going and give your Vehicle
Identification Number (VIN).
