2002 TOYOTA TACOMA octane

’02 Tacoma U (L/O 0109)
1902002 MY TACOMA_U (OM35786U)
OCTANE RATING
Select Octane Rating 87 (Research Oc-
tane Number 91) or higher.
Use of unleaded gasoline with an octane
rating or research octane number lower
than stated above will cause persistent
heavy knocking. If it is severe, this will
lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no need
of concern.
GASOLINE CONTAINING DETERGENT
ADDITIVES
Toyota recommends the use of gasoline
that contains detergent additives to
avoid buildup of engine deposits.
However, all gasoline sold in the U.S.
contains detergent additives to keep clean
and/or clean intake systems.QUALITY GASOLINE
Automotive manufacturers in the U.S.,
Europe and Japan have developed a
specification for quality fuel named
WorldWide Fuel Charter (WWFC) that
is expected to be applied world wide.
The WWFC consists of three categories
that depend on required emission lev-
els. In the U.S., category 3 has been
adopted. The WWFC improves air quali-
ty by providing for better emissions in
vehicle fleets, and customer satisfaction
through better vehicle performance.
CLEANER BURNING GASOLINE
Cleaner burning gasoline, including re-
formulated gasoline that contains oxy-
genates such as ethanol or MTBE is
available in many areas.
Toyota recommends the use of cleaner
burning gasoline and appropriately blended
reformulated gasoline. These types of gas-
oline provide excellent vehicle perfor-
mance, reduce vehicle emissions, and im-
prove air quality.
OXYGENATES IN GASOLINE
Toyota allows the use of oxygenate
blended gasoline where the oxygenate
content is up to 10% ethanol or 15%
MTBE. If you use gasohol in your
Toyota, be sure that it has an octane
rating no lower than 87.
Toyota does not recommend the use of
gasoline containing methanol.
GASOLINE CONTAINING MMT
Some gasoline contain an octane en-
hancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota 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 Toyota dealer for ser-
vice.
GASOLINE QUALITY
In a very few cases, you may experience
driveability problems caused by the partic-
ular gasoline that you are using. If you
continue to have unacceptable driveability,
try changing gasoline brands. If this does
not rectify your problem, then consult your
Toyota dealer.

NOTICE
Do not use gasohol other than
stated above. It will cause fuel sys-
tem damage or vehicle performance
problems.
 If driveab ility problems occur (poor
hot starting, vaporizing, engine
knock, etc.), discontinue the use.
 Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.
FUEL TANK CAPACITY
Twowheel drive models
except Pre Runner
60 L (16.0 gal., 13.3 Imp. gal.)
Fourwheel drive models
and Pre Runner 70 L (18.5 gal., 15.4 Imp. gal.) If you plan to drive your Toyota in
another country...
First,
comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel (unleaded and minimum octane
number).The threeway catalytic converter is an
emission control device installed in the
exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION
Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
