*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Warm up and turn off the engine, wait more than 5 minutes,
and check the oil level on the dipstick.

“Toyota Genuine Motor Oil” is used in your Lexus vehicle.
Lexus recommends the use of approved “Toyota Genuine Motor
Oil”. Another motor oil of matching quality can also be used.
Oil grade:
5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”,
SN “Resource-Conserving” or ILSAC multigrade engine oil
15W-40 and 20W-50:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures,
the engine may become diffi-
cult to start, so SAE 5W-30
engine oil is recommended.
Oil viscosity (10W-30 is explained here as an example):
• The 10W in 10W-30 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 30 in 10W-30 indicates the viscosity 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.
Temperature range anticipated
before next oil change.
