INFORMATION BEFORE DRIVING YOUR TOYOTA199
FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
DOil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
DOil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high−speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.Oil consumption:Max. 1.0 L per 1000
km (1.1 qts./600 miles, 0.9 lmp.qts./600
miles)
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with fuel or moisture, making it
appear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear that oil has been excessively con-
sumed while driving at high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” on
page 264 in Section 7−2.

Facts about engine oil
consumption

214STARTING AND DRIVING
Driving in the rain
Driving on a slippery road surface
Drive carefully when it is raining, because
visibility will be reduced, the windows may
become fogged−up, and the road will be
slippery.
DDrive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
DRefrain from high speeds when driving
on an expressway in the rain, because
there may be a layer of water between
the tires and the road surface, prevent-
ing the steering and brakes from oper-
ating properly.
CAUTION
DSudden braking, acceleration and
steering when driving on a slippery
road surface may cause tire slip-
page and reduce your ability to
control the vehicle, resulting in an
accident.
DSudden changes in engine speed,
such as sudden engine braking,
may cause the vehicle to skid, re-
sulting in an accident.
DAfter driving through a puddle,
lightly depress the brake pedal to
make sure that the brakes are func-
tioning properly. Wet brake pads
may prevent the brakes from func-
tioning properly. If the brakes on
only one side are wet and not func-
tioning properly, steering control
may be affected, resulting in an ac-
cident.
When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
serious damage to the vehicle.
NOTICE
Driving on a flooded road may cause
the engine to stall as well as cause
serious vehicle malfunctions such as
shorts in electrical components and
engine damage from water immersion.
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Toyota
dealer check brake function, changes
in quantity and quality of engine oil,
transaxle fluid, etc. and lubricant con-
dition for the bearings and suspen-
sion joints (where possible) and the
function of all joints and bearings.

ENGINE OIL SELECTION
Your Toyota vehicle is filled with “Toyota
Genuine Motor Oil” at the factory. 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 and10W−30:
API grade SL “Energy−Conserving”,
SM “Energy−Conserving” or ILSAC
multigrade engine oil
15W−40 and 20W−50:
API grade SL or SM multigrade engine
oil
Recommended viscosity (SAE):
SOIL35
Temperature range anticipated before
next oil change.
Preferred
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 SAE10W−30 or a higher
viscosity engine oil in extremely low
temperatures, the engine may become
difficult to start, so SAE 5W−30 or low-
er viscosity engine oil is recommended.
The 0W portion of the oil viscosity rating
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.
The20in0W−20 indicates the oil
viscosity when the oil is at its operating
temperature. An oil with a higher viscosity
may be better suited if the vehicle is
operated at high speeds, or under extreme
load conditions.
