■Oil capacity (Drain and refill [Reference*])
*: The engine oil capacity is a reference quantity to be used when changing the engine
oil. Warm up and turn off the engine, wait more than 5 minutes, and check the oil level
on the dipstick.
■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus recom-
mends 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
1 5 W- 4 0 a n d 2 0 W- 5 0 :
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. How-
ever, 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
0 W-20, 5W-20 or 5W-30 engine
oil is recommended.

IS250_EE(OM53C51E)
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.
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-
Conserving” means that the oil has
fuel-saving and environmental pro-
tection capabilities.
ILSAC Certification Mark
The International Lubricant Specification Advisory Committee (ILSAC) 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 the 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 autho-
rized 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 vehi-
cle 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.
