■Engine oil consumption
A certain amount of engine oil will be con-
sumed while driving. In the following situa- tions, oil consumption may increase, and engine oil may need to be refilled in
between oil maintenance intervals.
●When the engine is new, for example
directly after purchasing the vehicle or after replacing the engine
●If low quality oil or oil of an inappropriate viscosity is used
●When driving at high engine speeds or with a heavy load, or when driving while accelerating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently through heavy traffic
■After changing the engine oil (LC500h)
The engine oil maintenance data should be reset. Perform the following procedures:
1 While the vehicle is stopped, press
of the meter control switches.
2 Press or of the meter control
switches, and select .
3 Press or of the meter control

■Oil capacity (Drain and refill [Ref-
erence*])
*: 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.
■Engine oil selection
“Toyota Genuine Motor Oil” is used in
your Lexus vehicle. Lexus recom-
mends 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” or SN
“Resource-Conserving”; or ILSAC
multigrade engine oil
15W-40:
API grade SL, SM or SN multigrade
engine oil
Recommended viscosity (SAE):
SAE 5W-30 is filled into your Lexus
vehicle at manufacturing, and the best
choice for good fuel economy and
good starting in cold weather.
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 5W-30 engine
oil is recommended.
Temperature range anticipated
before next oil change.
Preferred
Oil viscosity (5W-30 is explained here
as an example):
• The 5W in 5W-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 5W-30 indicates the vis-
cosity characteristic of the oil when
the oil is at high temperature. An oil
