: The engine oil capacity is a reference
quantity to be used when changing the
engine oil. Warm up the engine and turn
off the hybrid system, wait more than 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:
0W-16:
API grade SN "Resource-Conserving"
or SN PLUS "Resource-Conserving"
multigrade engine oil
0W-20, 5W-20, 5W-30 and 10W-
30:
API grade SL "Energy-Conserving",
SM "Energy-Conserving", SN
"Resource-Conserving" or SN PLUS
"Resource-Conserving"; or ILSAC
multigrade engine oil
15W-40:
API grade SL, SM, SN or SN PLUS
multigrade engine oil
Recommended viscosity (SAE):
8-1. Specifications
Temperature range anticipated
A
before next oil change
If you use SAE 10W-30 or a higher vis-
cosity engine oil in extremely low tem-
peratures, the engine may become
difficult to start, so SAE 0W-16, 0W-
20, 5W-20 or 5W-30 engine oil is
recommended.
Oil viscosity (0W-16 is explained here
as an example):
• The 0W in 0W-16 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 16 in 0W-16 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.
