QUALITY GASOLINE
Automotive manufacturers in the U.S.,
Europe and Japan have developed a
specification for quality fuel
World–Wide Fuel Charter (WWFC) that
is expected to be applied worldwide.
The WWFC consists of four categories
that depend on required emission lev-
els. In the U.S., category 3 or 4 has
been adopted. The WWFC improves air
quality by providing for better emis-
sions in vehicle fleets, and customer
satisfaction through better vehicle per-
formance.
CLEANER BURNING GASOLINE
Cleaner burning gasoline, including re-
formulated gasoline that contains oxy-
genates such as ethanol or MTBE is
available in many areas.
Scion recommends the use of cleaner
burning gasoline and appropriately blended
reformulated gasoline. These types of gas-
oline provide excellent vehicle
mance, reduce vehicle emissions, and im-
prove air quality.
OXYGENATES IN GASOLINE
Scion allows the
blended gasoline where the oxygenate
named content is up to 10% ethanol or 15%
MTBE. If you use gasohol
Scion, be sure that it has an octane
rating no lower than 87.
Scion does not recommend the use of
gasoline containing methanol.
GASOLINE CONTAINING MMT
Some gasoline contains an octane en-
hancing additive called MMT (Methylcy-
cropentadienyl Manganese Tricarbonyl).
Scion does not recommend the use of
gasoline that contains MMT. If fuel con-
taining MMT is used, your emission con-
trol system may be adversely affected.
The Malfunction Indicator Lamp on the in-
strument cluster may come on. If this hap-
pens, contact your Scion dealer for ser-
vice.

GASOLINE QUALITY
In a very few cases, you may experience
use of oxygenate
drivability problems caused by the particu-
lar gasoline that you are using. If you
continue to have unacceptable drivability,

try changing gasoline brands. If this does
not rectify your problem, then consult your
Scion dealer.
