: The engine oil capacity is a reference
quantity to be used when changing the
engine oil. When actually adding the
engine oil, make sure that the oil level is
between the low level mark and refill
upper limit mark (P.438). Warm up
and turn off the engine, wait about 5
minutes, and check the oil level on the
dipstick.
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 following
grade and viscosity.
Oil grade: ILSAC GF-6A multigrade
engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good starting
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.

A
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 vis-
cosity 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 con-
ditions.
How to read oil container label:
The International Lubricant Specifica-
tion Advisory Committee (ILSAC)
Certification Mark is added to some oil
containers to help you select the oil you
should use.
