PRIUS +_OM_OM47821E_(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 5W-30 or lower vis-
cosity engine oil is recom-
mended.
Temperature range anticipated before
next oil change.

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: The oil quality desig-
nation by API (American Petro-
leum Institute) (SN)
Center portion: The SAE viscosity
grade (SAE 0W-20)
Lower portion:
“Resource-conserving” means
that the oil has fuel saving and
environmental protection capabili-
ties.
ILSAC Certification Mark
The ILSAC (International Lubri-
cant Standardization and
Approval Committee) certification
Mark is displayed on the front of
the container.

Fuel infor mation
Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Toyota has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
If your engine knocks
Consult any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
You may occasionally notice light knocking for a short time while acceler-
ating or driving uphill. This is normal and there is no need for concern.
Except EU area:
Your vehicle must use only unleaded gasoline.
For optimum engine performance, select unleaded gasoline with a
Research Octane Number of 95 or higher.
EU area:
Your vehicle must use only unleaded gasoline conforming to Euro-
pean standard EN228.
For optimum engine performance, select unleaded gasoline with a
Research Octane Number of 95 or higher.

NOTICE
Notice on fuel quality
Do not use improper fuels. If improper fuels are used the engine will be
damaged.
Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its
effectiveness and emission control system to function improperly.
Gasoline engine (EU area): Bioethanol fuel sold under names such as
“E50” or “E85” and fuel containing a large amount of ethanol should not be
used. The use of these fuels will damage the vehicle’s fuel system. In case
of any doubt, ask any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
Gasoline engine (except EU area): Bioethanol fuel sold under names such
as “E50” or “E85” and fuel containing a large amount of ethanol should not
be used. Your vehicle can use gasoline mixed with 10% max ethanol. The
use of fuel with more than 10% ethanol content (E10) will damage the
vehicle’s fuel system. You must ensure that refueling is carried out only
from a source where fuel specification and quality can be guaranteed. In
case of any doubt, ask any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
