Facts about engine oil

consumption

FUNCTIONS OF ENGINE OIL

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.

D Keep the back door closed while

driving. An open or unsealed back

door may cause exhaust gases to

be drawn into the vehicle.

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.

More oil is consumed by high−speed driv-

ing and frequent acceleration and decel-

eration.

D To allow proper operation of your

vehicle’s ventilation system, keep

the inlet grilles in front of the wind-

shield clear of snow, leaves, or oth-

er obstructions.

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.

A new engine consumes more oil, since

its pistons, piston rings and cylinder walls

have not become conditioned.

D If you smell exhaust fumes in the

vehicle, drive with the windows

open and the back door closed.

Have the cause immediately located

and corrected.

Oil consumption: Max. 1.0 L per 1000

km (1.1 qt./600 miles, 0.9 lmp. qt./600

miles)

D Oil 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.

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.

D Oil 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 diluting ingredients evaporate out

when the vehicle is then driven at high

speeds, as on an expressway, making it

appear that oil is excessively consumed

after driving at high speeds.

IMPORTANCE OF ENGINE OIL LEVEL

CHECK

The tandem master cylinder brake system

is a hydraulic system with two separate

sub−systems. If either sub−system should

fail, the other will still work. However, the

pedal will be harder to press, and your

stopping distance will be increase. Also,

the brake system warning light may come

on.

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.

CAUTION

Do not drive your vehicle with only a

single brake system. Have your

brakes fixed immediately.

NOTICE

Failure to check the oil level regularly

could lead to serious engine trouble

due to insufficient oil.

Your engine is fitted with iridium−tipped

spark plugs.

BRAKE BOOSTER

The brake booster uses engine vacuum to

power−assist the brakes. If the engine

should quit while you are driving, you can

bring the vehicle to a stop with normal

pedal pressure. There is enough reserved

vacuum for one or two stops—but no

more!

NOTICE

For detailed information on oil level check,

see “Checking the engine oil level” in Sec-

tion 7−2.

Use only iridium−tipped spark plugs

and do not adjust gaps for your en-

gine performance and smooth drive-

ability.

Effective way to press the ABS brake

pedal: When the anti−lock brake system

function is in action, you may feel the

brake pedal pulsating and hear a noise.

In this situation, to let the anti−lock

brake system work for you, just hold the

brake pedal down more firmly. Do not

pump the brake in a panic stop. This

will result in reduced braking performan-

ce.

CAUTION

tivated, the following conditions may

occur. They do not indicate a malfunc-

tion of the system:

D Do not pump the brake pedal if the

engine stalls. Each push on the

pedal uses up your reserved vacu-

um.

D You may hear the anti−lock brake sys-

tem operating and feel the brake pedal

pulsating and the vibrations of the ve-

hicle body and steering wheel. You

may also hear the motor sound in the

engine compartment even after the ve-

hicle is stopped.

D Even if the power assist is com-

pletely lost, the brakes will still

work. But you will have to push the

pedal hard, much harder than nor-

mal. And your braking distance will

increase.

The anti−lock brake system becomes op-

erative after the vehicle has accelerated

to a speed in excess of approximately 10

km/h (6 mph). It stops operating when the

CAUTION

approximately 5 km/h (3 mph).

The anti−lock brake system is designed

to help prevent lock−up of the wheels

during a sudden braking or braking on

slippery road surfaces. This assists in

providing directional stability and steer-

ing performance of the vehicle under

these circumstances.

Depressing the brake pedal on slippery

road surfaces such as on a manhole cov-

er, a steel plate at a construction site,

joints in a bridge, etc. on a rainy day

tends to activate the anti−lock brake sys-

tem.

Do not overestimate the anti−lock

brake system: Although the anti−lock

brake system assists in providing ve-

hicle control, it is still important to

drive with all due care and maintain

a moderate speed and safe distance

from the vehicle in front of you, be-

cause there are limits to the vehicle

stability and effectiveness of steering

wheel operation even with the anti−

lock brake system on.

You may hear a click or motor sound in

the engine compartment for a few seconds

when the engine is started or just after

the vehicle begins to move. This means

that the anti−lock brake system is in the

self check mode, and does not indicate a

malfunction.

If tire grip performance exceeds its

capability, or if hydroplaning occurs

during high speed driving in the rain,

the anti−lock brake system does not

provide vehicle control.

appropriate pressure: The anti−lock

brake system detects vehicle speeds

using the speed sensors for respec-

tive wheels’ turning speeds. The use

of tires other than specified may fail
