Vehicle specifications
nGasoline 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.
nGasoline quality standards
lAutomotive 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.
lThe WWFC consists of four categories that are based on required emission
levels. In the US, category 4 has been adopted.
lThe WWFC improves air quality by lowering emissions in vehicle fleets, and
customer satisfaction through better performance.
nLexus recommends the use of gasoline containing detergent additives
lLexus recommends the use of gasoline that contains detergent additives to
avoid build-up of engine deposits.
lAll gasoline sold in the US contains detergent additives to clean and/or keep
clean intake systems.
nLexus recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxygen-
ates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many
areas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
reformulated gasoline. These types of gasoline provide excellent vehicle perfor-
mance, reduce vehicle emissions and improve air quality.
nLexus does not recommend blended gasoline
lLexus allows the use of oxygenate blended gasoline where the oxygenate con-
tent is up to 10% ethanol or 15% MTBE.
lIf you use gasohol in your Lexus, be sure that it has an octane rating no lower
than 87.
lLexus DOES NOT recommend the use of gasoline containing methanol.

6-1. Specifications
nLexus does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus DOES NOT recommend the use of gasoline that contains MMT. If fuel con-
taining MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
NOTICE
nNotice on fuel quality
lDo not use improper fuels. If improper fuels are used the engine will be damaged.
lDo not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic convert-
ers causing the emission control system to malfunction.
lDo not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance problems.
lIS250: Use of unleaded gasoline with an octane rating lower than 91 may result
in engine knocking. Persistent knocking can lead to engine damage and should
be corrected by refueling with higher octane unleaded gasoline.
lIS350: Use of unleaded gasoline with an octane rating lower than 91 may result
in engine knocking and significantly reduced performance. Persistent knocking
can lead to engine damage and should be corrected by refueling with higher
octane unleaded gasoline.
nFuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor hot start-
ing, vaporization, engine knocking, etc.), discontinue the use of that type of fuel.
nWhen refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.
