Vehicle specifications
■ Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ Gasoline quality
In very few cases, driveability problems may be caused by the brand of gas-
oline you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your Toyota dealer.
■ Gasoline quality standards
● Automotive manufacturers in the U.S.A., Europe and Japan have devel-
oped a specification for fuel quality called the World-Wide Fuel Charter
(WWFC), which is expected to be applied worldwide.
● The WWFC consists of four categories that are based on required emis-
sion levels. In the U.S., category 4 has been adopted.
● The WWFC improves air quality by lowering emissions in vehicle fleets,
and improves customer satisfaction through better performance.
■ E85 fuel (Flex-fuel vehicles)
● E85 fuel is a blend of 85% ethanol and 15% gasoline. However, E85
does not necessarily contain 85% ethanol. The ethanol content of E85 is
required by ASTM to be between 70% and 85%.
For example, in cold climates the ethanol content of E85 may be reduced
during the winter months to maintain cold weather starting performance.
When the ambient temperature is below 32°F (0°C), refuel with regular
unleaded gasoline if possible.
● E85 has less energy per gallon than gasoline, so you will need to fill your
fuel tank more frequently when using E85.
