CT200h_OM_OM76067E_(EE)Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus
recommends 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”,
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 manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 oil is not avail-
able, 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 diffi-
cult to start, so SAE 5W-30 or
lower viscosity engine oil is
recommended.

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 oper-
ated at high speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil contain-
ers to help you select the oil you should use.
API Service Symbol
Top portion: The oil quality des-
ignation by API (American
Petroleum Institute) (SN)
Center portion: The SAE vis-
cosity grade (SAE 0W-20)
Lower portion:
“Resource-Conserving” means
that the oil has fuel saving and
environmental protection capa-
bilities.
ILSAC Certification Mark
The ILSAC (International
Lubricant Standardization and
Approval Committee) Certifica-
tion Mark is displayed on the
front of the container.

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 will cause the three-way catalytic converter to lose its
effectiveness and emission control system to function improperly.
Gasoline engine (EU area): Bioethanol fuel sold under names such as
“E50” or “E85” and fuel containing 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.
Gasoline engine (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.
