■Engine oil selection
“Toyota Genuine Motor Oil SAE 0W-20 for Direct Injection Turbo Gasoline
Engines” is used in your Lexus vehicle. Use Lexus approved “Toyota Genuine
Motor Oil SAE 0W-20 for Direct In jection Turbo Gasoline Engines” or
equivalent to satisfy the following grade and viscosity.
Oil grade: “Toyota Genuine Motor Oil SAE 0W-20 for Direct Injection Turbo
Gasoline Engines” or ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20
at the next oil change.

Vehicle specifications
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 viscos ity 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 label:
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is added
to some oil containers to help you
select the oil you should use.
