Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Lexus vehicle at manufacturing,
and the best choice for good fuel
economy and good starting in
cold weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used.
However, it should be replaced
with SAE 0W-20 at the next oil
change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures, the
engine may become difficult to
start, so SAE 0W-20, 5W-20 or
5W-30 engine oil is recom-
mended.
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 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.
Temperature range anticipated

How to read oil container labels:
Either or both API registered marks are added to some oil containers
to help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation by
American Petroleum Institute
(API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-Con-
serving” means that the oil has fuel-
saving and environmental protec-
tion capabilities.
ILSAC Certification Mark
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is dis-
played on the front of the container.

■Engine oil selection (GS350)
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus rec-
ommends the use of approved “Toyota Genuine Motor Oil”. Another
motor oil of matching quality can also be used.
Oil grade:
0W-20, 5W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40 and 20W-50:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Lexus vehicle at manufacturing,
and the best choice for good fuel
economy and good starting in
cold weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used.

5W-30 engine oil is recom-

Fuel information
■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.
■If your engine knocks
●Consult any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
●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.
EU area:
Your vehicle must use only unleaded gasoline conforming to European
standard EN228.
For optimum engine performance, select unleaded gasoline with a
Research Octane Number of 95 or higher.
Except EU area:
Your vehicle must use only unleaded gasoline.
For optimum engine perf ormance, select unleaded gasoline with a
Research Octane Number of 95 or higher.

NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be dam-
aged.
●Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its effective-
ness and the emission control system to function improperly.
●EU area: Bioethanol fuel sold under names such as “E50” or “E85” and fuel con-
taining a large amount of ethanol should not be used. The use of these fuels will
damage the vehicle’s fuel system. In case of any doubt, ask any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
●Except EU area: Bioethanol fuel sold under names such as “E50” or “E85” and
fuel containing a large amount of ethanol should not be used. Your vehicle can
use gasoline mixed with 10% max ethanol. The use of fuel with more than 10%
ethanol content (E10) will damage the vehicle’s fuel system. You must ensure that
refueling is carried out only from a source where fuel specification and quality
can be guaranteed. In case of any doubt, ask any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
