Maintenance and care
LS600h/LS600hL_EE(OM50G20E)
■Engine oil consumption
A certain amount of engine oil will be consumed 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
CAUTION
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammation and skin cancer, so care should be taken to avoid
prolonged and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do not dis-
pose of used oil and filters in household trash, in sewers or onto the ground.
Call any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, service station or auto parts store for information con-
cerning recycling or disposal.
●Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
●Avoid overfilling, or the engine could be damaged.
●Check the oil level on the dipstick every time you refill the vehicle.
●Be sure the engine oil filler cap is properly tightened.

Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Lexus vehicle at manufacturing,
and the best choice for good fuel
economy and good starting in
cold weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used.
However, it should be replaced
with SAE 0W-20 at the next oil
change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures, the
engine may become difficult to
start, so SAE 0W-20 or 5W-30
engine oil is recommended.
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 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 conditions.
Temperature range anticipated
before next oil change.

How to read oil container labels:
Either or both API registered marks are added to some oil containers
to help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation by
American Petroleum Institute
(API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-
Conserving” means that the oil has
fuel-saving and environmental pro-
tection capabilities.
ILSAC Certification Mark
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is dis-
played on the front of the container.
