Fuel
Lubrication system
*5W-30 is an oil that provides optimal levels of fuel efficiency
Oil viscosity
• “5W” oils are for use in ar
eas where the ambient temperature is -13 F (-
25 C) or above. “10W” oils are fo r areas where the ambient tempera -
ture is -4 F (-
20C) or above. Oils with smaller figures are better for
engine starting in cold we ather and fuel efficiency.
• “XX-30” indicates oil viscosity. O ils with lar
ger figures have better ther-
mostability and are good for high-speed driving.

Fuel information
■Fuel tank opening for unleaded gasoline
●To help prevent incorrect fueling, your Lexus has a fuel tank opening that will
only accept the special nozzle on unleaded fuel pumps.
●If premium fuel is not available, you may temporarily use unleaded gasoline with
an Octane Rating as low as 87 (Research Octane Number 91).
■If your engine knocks ...
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating
or driving up hills. 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.
■Gasoline quality standards
●Automotive 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.
●The WWFC consists of four categories that are based on required emission
levels. In the US, category 3 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets, and
customer satisfaction through better vehicle performance.
Your vehicle must use on ly unleaded gasoline. 
Select premium unleaded gasoline with an
Octane Rating of 91 (Research
Octane Number 96) or higher for optimum engine performance.
At minimum, the gasoline you use sh ould meet the specifications of
ASTM D4814 in the USA and CGSB 3.5-M93 in Canada.

6-1. Specifications
■Lexus recommends the use of gasoline containing detergent additives
●Lexus recommends the use of gasoline that contains detergent additives to
avoid build-up of engine deposits.
●All gasoline sold in the US contains detergent additives to clean and/or keep
clean intake systems.
■Lexus recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reform ulated gasoline that conta
ins oxygen-
ates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many
ar

eas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
r
eformulated gasoline. These types of gasoline provide excellent vehicle perfor -
mance, reduce vehicle emissions, and improve air quality.
■Lexus does not recommend blended gasoline
●Lexus allows the use of oxygenate blended gasoline where the oxygenate con -
tent is up to 10% ethanol or 15% MTBE.
●If you use gasohol in your Lexus, be sure that it has an octane rating no lower
than 87.
●Lexus DOES NOT recommend the use of gasoline containing methanol.
■Lexus does not recommend gasoline containing MMT
Some gasolines contain an octane enhanc
ing additive called MMT (Methylcyclo-
pentadienyl 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 inst rum
ent cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
