Lubrication system■ Specified engine oil for the LFA
*1: The oil filters used are exclusive to the LFA. When the oil is changed, the oil fil-
ters should also be replaced.
*
2: The lifetime of the vehicle depends greatly on the quality of oil used. The use of “Mobil 1 5W-50” is most suitable for your vehicle and is recommended.

■Engine oil viscosity
●The 5W portion of the oil viscosity rating
indicates the characteristic of the oil
which allows cold startability. Oils with a lower value before the W allow for eas-
ier starting of the engine in cold weather.
●The 50 in 5W-50 indicates the oil viscosit y when the oil is at its operating tem-
perature. An oil with a higher viscosity may be better suited if the vehicle is
operated at high speeds, or under extreme load conditions.
NOTICE
■To prevent engine damage
If “Mobil 1 5W-50” is not available, another oil of equivalent quality to “Mobil 1
5W-50” may be used. In this case, do not start the engine if the engine coolant or
oil temperature is below 5 F (-15C), and do not drive the vehicle under extreme
load conditions.

Be careful not to subject the CCM brake discs to any kind of strong impact.
Even if there is no obvious damage, in the following situations, have the vehicle
inspected by your Lexus dealer:
●If the vehicle is involved in an accident that may affect the suspension and wheels
●If a CCM brake disc sustains an impact during the removal or installation of the
wheels
●If the brake pads have worn out and the metal part of the pad is in contact with the
CCM brake disc surface

Fuel information
Your vehicle must use only unleaded gasoline.
Premium unleaded gasoline with an octane rating of 91 (Research Octane
Number 96) or higher is required for optimum engine performance.
At minimum, the gasoline you use should meet the specifications of
ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that only
accommodates 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., Europe and Japan have developed a
specification for fuel quality called the World-Wide Fuel Charter (WWFC),
which is expected to be applied worldwide.
●The WWFC consists of four categories 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 gasoline 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 detergent additives to clean and/or keep
clean intake systems.
