*: The engine oil capacity is a reference quantity to be used when changing the engineoil. 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 Ge nuine Motor Oil”. Another motor oil of
matching quality can also be used.

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
0W-20 or 5W-30 engine oil is rec-
ommended.

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 viscosit y 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-Conserv-
ing” means that the oil has fuel-saving
and environmental protection capa-
bilities.

“Toyota Genuine Motor Oil SAE 0W-20 for Downsized Turbo Gasoline
Engines” is used in your Lexus vehicle. Use Lexus approved “Toyota Genuine
Motor Oil SAE 0W-20 for Downsized Turbo Gasoline Engines” or equiva-
lent to satisfy the following grade and viscosity.
Oil grade:
“Toyota Genuine Motor Oil SAE 0W-20 for Downsized Turbo Gasoline
Engines” or API grade SL “Energy-Co nserving”, SM “Energy-Conserving” or
SN “Resource-Conserving”; or ILSAC multigrade engine oil
