Fuel information
■Fuel tank opening for unleaded gasoline
●To help prevent incorrect fueling, your Lexus has a fuel tank opening that will
only accept the special nozzle on unleaded fuel pumps.
●If premium fuel is not available, you may temporarily use unleaded gasoline with
an Octane Rating as low as 87 (Research Octane Number 91).
■If your engine knocks ...
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating
or driving up hills. This is normal and there is no need for concern.
■Gasoline quality
In very few cases, driveability problems may be caused by the brand of gasoline you
ar

e 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 US, Europe and Japan have developed a
specification for fuel quality called World-Wide Fuel Charter (WWFC) that is
expected to be applied worldwide.
●The WWFC consists of four categories that are based on required emission
levels. In the US, category 3 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets, and
customer satisfaction through better vehicle performance.
Your vehicle must use on ly unleaded gasoline. 
Select premium unleaded gasoline with an
Octane Rating of 91 (Research
Octane Number 96) or higher for optimum engine performance.
At minimum, the gasoline you use sh ould meet the specifications of
ASTM D4814 in the USA and CGSB 3.5-M93 in Canada.
