Vehicle specifications
■Engine oil selection
“Toyota Genuine Motor Oil” is used in y
our 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 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
star

ting in cold weather.
If SAE 0W-20 is not available,
S
AE 5W-20 oil may be used.
However, it must be replaced with
SAE 0W-20 at the next oil
change.
The 0W portion of the oil viscosity rating indicates the characteristic of the oil
which allows cold startability. Oils wi th 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
temper
ature. 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 St andar
dization and Approval Com-
mittee) Certification Mark is added to some oil containers to help y
ou
select the oil you should use.
