6-1. Specifications
Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only
ac
commodates the special nozzle on unleaded fuel pumps.
■If premium gasoline is not available
If 91 Octane cannot be obtained, you ma y use unleaded gasolin
e with an Octane
Rating as low as 87 (Research Octane Number 91). 
However, use of unleaded fuel with an Octane Rating lower than 91 may result in
engine knocking (G
S350 only: or drasticall y reduce output to protect itself while
driving with heavy load). Persistent kn ocking can lead to engine damage and
should be corrected 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
ar
e 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 only unleaded gasoline.
Premium unleaded gasoline with an Octane Rating 91 (Research Octane
Number 9
6) 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.
