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.■
Gasoline quality standards ●
Automotive manufacturers in the US, Europe and Japan have developed a
specification for fuel quality called the 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 4 has been adopted.●
The WWFC improves air quality by lowering emissions in vehicle fleets, and
customer satisfaction th rough better performance.You must only use unleaded gasoline in your vehicle.
Select octane rating 87 (Research Octane Number 91) or higher. Use of
unleaded gasoline with an octane rating lower than 87 may result in engine
knocking. Persistent knocking can lead to engine damage.
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.
