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 this premium fuel is not available, you may use unleaded gasoline with an Octane
Rating of 87 or so (Research Octane Number 91).
IS250: The use of such gasoline will cause persistent heavy knocking. If severe, this
will lead to engine damage.
IS350: The use of such gasoline may cause the engine to knock or drastically
reduce output to protect itself while driving with a heavy load. To avoid this, refill the
tank with premium unleaded gasoline as soon as possible.
■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 of 91 (Research
Octane Number 96) or higher required for optimum engine performance.
At minimum, the gasoline you us e should meet the specifications of
ASTM D4814 in the U.S.A. an d CGSB3.5-M93 in Canada.
