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”
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 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 0W-20,
5W-20 or 5W-30 engine oil is
recommended.
Temperature range anticipated
before next oil changePreferred

GS450h_300h_OM_OM30D53E_(EE)
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: “API SERVICE
SN” means the oil quality desig-
nation 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
protection capabilities.
ILSAC Certification Mark
The International Lubricant
Specification Advisory Com-
mittee (ILSAC) Certification
Mark is displayed on the front
of the container.
