■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 ma y be caused by the brand of gasoline you
are using. If driveability problems persist, try changing the brand of gasoline. If this
does not correct the problem, consult your Lexus dealer.
■Gasoline quality standards
●Automotive manufacturers in the U.S.A., Europe and Japan have developed 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 emission 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.
Fuel information
You must only use unleaded gasoline in your vehicle.
Select premium unleaded gasoline with an octane rating of 91
(Research Octane Number 96) or higher required for optimum engine
performance. If 91 octane cannot be obtained, you may use unleaded
gasoline with an octane rating as low as 87 (Research Octane Number
91). Use of unleaded gasoline with an octane rating lower than 91 may
result in engine knocking and signif icantly reduced performance. Per-
sistent knocking can lead to engine damage and should be corrected
by refueling with higher octane unleaded gasoline.
At minimum, the gasoline you us e should meet the specifications of
ASTM D4814 in the U.S.A.
