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

GS350/250_EE (OM30C36E)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.

8468-1. Specifications
GS350/250_EE (OM30C36E)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 con-
ditions.
How to read oil container labels:
Either or both API registered marks are added to some oil con-
tainers 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-Con-
serving” means that the oil has
fuel saving and environmental
protection capabilities.
ILSAC Certification Mark
The ILSAC (International
Lubricant Standardization and
Approval Committee) Certifica-
tion Mark is displayed on the
front of the container.
