■Engine oil selection (RC350)
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20
at the next oil change.
Oil viscosity (0W-20 is explained here as an example): • The 0W in 0W-20 indicates the characteristic of the oil which allows cold startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscos ity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
How to read oil container label:
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is added
to some oil containers to help you
select the oil you should use.

■Engine oil selection (RC F)
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 5W-30
SAE 5W-30 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 5W-30 is not available, SAE
10W-30 oil may be used. However,
it must be replaced with SAE 5W-
30 at the next oil change.
Oil viscosity (5W-30 is explained here as an example): • The 5W in 5W-30 indicates the characteristic of the oil which allows cold startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 30 in 5W-30 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.

■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that only accom-
modates the special nozzle on unleaded fuel pumps.
■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 U.S.A., Eu rope and Japan have developed a specifi-
cation for fuel quality called the World-Wi de Fuel Charter (WWFC), which is expected
to be applied worldwide.
●The WWFC consists of four cat egories that are based on required emission levels. In
the U.S., category 4 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets, and improves
customer satisfaction through better performance.
■Recommendation of the use of gasoli ne containing detergent additives
●Lexus recommends the use of gasoline that contains detergent additives to avoid the
build-up of engine deposits.
●All gasoline sold in the U.S.A. contains minimum detergent additives to clean and/or
keep clean intake systems, per EPA’s lowest additives concentration program.
●Lexus strongly recommends the use of Top Ti er Detergent Gasoline. For more informa-
tion on Top Tier Detergent Gasoline and a list of marketers, please go to the official
website www.toptiergas.com.
Fuel information
You must only use unleaded gasoline in your vehicle.
Select premium unleaded gasoline with an octane rating of 91 (Research
Octane Number 96) or higher required for optimum engine performance. If
91 octane cannot be obtained, you may use unleaded gasoline with an octane
rating as low as 87 (Research Octane Number 91). Use of unleaded gasoline
with an octane rating lower than 91 may result in engine knocking and signifi-
cantly reduced performance. Persistent knocking can lead to engine damage
and should be corrected by refueling with higher octane unleaded gasoline.
At minimum, the gasoline you use should meet the specifications of ASTM
D4814 in the U.S.A..

■Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformul ated gasoline that contains oxygenates
such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas.
Lexus recommends the use of cleaner bu rning gasoline and appropriately blended
reformulated gasoline. These types of gaso line provide excellent vehicle performance,
reduce vehicle emissions and improve air quality.
■Non-recommendation of the use of blended gasoline
●If you use gasohol in your vehicle, be sure th at it has an octane rating no lower than 87.
●Lexus does not recommend the use of gasoline containing methanol.
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancin g additive called MMT (Methylcyclopenta-
dienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasolin e that contains MMT. If fuel containing
MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instru ment cluster may come on. If this happens,
contact your Lexus dealer for service.
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knocking fo r a short time while accelerating or driv-
ing uphill. This is normal and there is no need for concern.
●Use only gasoline containing up to 15% etha-
nol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol, includ-
ing from any pump labeled E30, E50, E85
(which are only some examples of fuel con-
taining more than 15% ethanol).DO NOT use gasoline con-
taining more than 15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)

NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be damaged.
●Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic converters
causing the emission control system to malfunction.
●Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system da mage or vehicle performance problems.
●Using unleaded gasoline with an octane number or rating lower than the level previ-
ously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■Fuel-related poor driveability
If poor driveability is encounte red after using a different type of fuel (poor hot starting,
vaporization, engine knocking, etc.), disc ontinue the use of that type of fuel.
■When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.
