Lubrication system
■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-30
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 5W-30 is not available,
SAE 10W-30 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.

6-1. Specifications
The 5W portion of the oil viscosity rating indicates a characteristic of the oil
which allows cold startability. Oils with a lower value before the W allow for eas-
ier starting of the engine in cold weather.
The 30 in 5W-30 indicates the oil viscosity when the oil is at its operating tem-
perature. An oil with a higher viscosity may be better suited if the vehicle is oper-
ated 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.
