■ Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the follow-
ing grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 5W-20 or 0W-20
SAE 5W-20 or 0W-20 engine oil
may be used. However, SAE 0W-
20 is the best choice for good fuel
economy and good starting in cold
weather.

The 0W portion of the oil viscosity rating 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 oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the vehicle
is operated at high speeds, or under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubricant Standardization and Approval Com-
mittee) Certification Mark is added to some oil containers to help you
select the oil you should use.
