FUEL
Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a
smaller fuel tank opening. The special nozzle on pumps
with unleaded fuel will fit it, but the larger standard nozzle
on pumps with leaded gas will not.
At a minimum, the gasoline you use should meet the
specifications of ASTM D4814 in the U.S.A. and CGSB
3.5±M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the three±way catalyticconverter to lose its effectiveness and theemission control system to function improperly.Also, this can increase maintenance costs.
Octane rating
Select Octane Rating 87 (Research Octane Number
91) or higher. For improved vehicle performance,
the use of premium unleaded gasoline with an
Octane Rating of 91 (Research Octane Number 96)
or higher is recommended.
Use of unleaded fuel 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
Lexus dealer.
However, now and then, you may notice light knocking
for a short time while accelerating or driving up hills. This
is no cause for concern.
Gasolines containing detergent additives
Lexus recommends the use of gasoline that contain
detergent additives to avoid build±up of engine
deposits.
For further details, ask your Lexus dealer or a local
gasoline retailer.
Quality gasoline
Automobile manufacturers in U.S., Europe and
Japan have developed a specification for quality
fuel named W orld±Wide Fuel Charter (WWFC) that is
expected to be applied world wide. The WWFC
consists of three categories that depend on
required emission levels. In the U.S., category 3 has
been adopted. The WWFC improves air quality by
providing for better emissions in vehicle fleets, and
