Fuels in Foreign Countries
Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty.
To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving.
