Maintenance and care
PRIUS +_OM_OM47841E_(EE)
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 dispose of used oil and filters in household trash, in sewers or onto the
ground. Call any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional, service station or auto parts store for
information concerning 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.

PRIUS +_OM_OM47841E_(EE)Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota
recommends the use of approved “Toyota Genuine Motor Oil”.
Another motor oil of matching quality can also be used.
Oil grade:
0W-20, 5W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40 and 20W-50:
API grade SL, SM or SN multigrade engine oil

Vehicle specifications
PRIUS +_OM_OM47841E_(EE)Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Toyota 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, 5W-20 or
5W-30 engine oil is recom-
mended.

PRIUS +_OM_OM47841E_(EE)
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.
How to read oil container labels:
Either or both API registered marks are added to some oil containers
to help you select the proper 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-Con-
serving” means that the oil has
fuel-saving and environmental
protection capabilities.
ILSAC Certification Mark
The International Lubricant Speci-
fication Advisory Committee
(ILSAC) Certification Mark is dis-
played on the front of the con-
tainer.
