Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only
accommodates the special nozzle on unleaded fuel pumps.
■If premium gasoline is not available
If 91 Octane cannot be obtained, you may use unleaded gasoline with an Octane
Rating as low as 87 (Reseach Octane Number 91). 
However, use of unleaded fuel with an Octane Rating lower than 91 may result in
engine knocking or drastically reduce output to protect itself while driving with a
heavy load. Persistent knocking can lead to engine damage and should be cor-
rected by refueling with higher octane unleaded gasoline.
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating
or driving uphill. 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
are using. If driveability problems persist, try changing the brand of gasoline. If this
does not correct the problem, consult your Lexus dealer.
Your vehicle must use on ly unleaded gasoline.
Premium unleaded gasoline with an Octane Rating 91 (Research Octane
Number 96) or higher required for optimum engine performance.
At minimum, the gasoline you use should meet the specifications of
ASTM D4814 in the U.S.A. an d CGSB3.5-M93 in Canada.
