FACTS ABOUT ENGINE OILCONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and
cooling the inside of the engine, and plays a major role
in maintaining the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some
engine oil during normal engine operation. The
causes of oil consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston rings and
cylinders. A thin film of oil is left on the cylinder wall
when a piston 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.
 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 temperature exhaust gases
also burn the oil used to lubricate the exhaust valve stems.
The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way
the vehicle is driven.
More oil is consumed under driving conditions such as
high speeds and frequent acceleration and
deceleration.
A new engine consumes more oil, since its pistons,
piston rings and cylinder walls have not become
conditioned.
When judging the amount of oil consumption, keep
in mind that the oil may have become diluted,
making it difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips
and consumes a normal 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 is excessively consumed after
driving at high speeds.

Look at the see±through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it
is between the ªFULLº and ªLOWº lines on the
reservoir. If the level is low, add ethylene±glycol
type coolant for a proper corrosion protection of
aluminum components.
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the
ªLOWº line, add coolant. Bring the level up to the ªFULLº
line.
Always use ethylene±glycol type coolant for a proper
corrosion protection of aluminum components. See
information in the next column. If the coolant level drops within a short time after
replenishing,
there may be a leak in the system. V isually
check the radiator, hoses, engine coolant filler cap,
radiator cap and drain cock and water pump.
If you can find no leak, have your Lexus dealer test the
cap pressure and check for leaks in the cooling system.

Coolant type selection
Use of improper coolants may damage your engine
cooling system. Your coolant must contain
ethylene±glycol type coolant for a proper corrosion
protection of your engine that contains aluminum
components. Use ªToyota Long Life Coolantº or
equivalent.
In addition to preventing freezing and subsequent
damage to the engine, this type of coolant will also
prevent corrosion. Further supplemental inhibitors or
additives are neither needed nor recommended.
Read the coolant container for information on freeze
protection. Follow the manufacturer's directions for how
much to mix with plain water (preferably demineralized
water or distilled water). The total capacity of the cooling
system is given on page 402.
We recommend to use 50% solution for your Lexus, to
provide protection down to about ±35C (±31F). When
it is extremely cold, to provide protection down to about
±50 C (±58F), 60% solution is recommended. Do not
use more than 70% solution for better coolant
performance.
NOTICE
Do not use alcohol type antifreeze or plain water alone.

REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bending, cracks
or heavy corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, a tire may slip off
a wheel or cause loss of handling control.
Replacement with used wheels is not recommended as
they may have been subjected to rough treatment or
high mileage and could fail without warning. Also, bent
wheels which have been straightened may have hidden
structural damage and therefore should not be used.
Never use an inner tube in a leaking wheel which is
designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to
ensure that they are equivalent to those removed in
load capacity, diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing life, brake cooling,
speedometer/odometer calibration, stopping ability,
headlight aim, bumper height, vehicle ground clearance,
and tire or snow chain clearance to the body and
chassis.
ALUMINUM WHEEL PRECAUTIONS
 When installing aluminum wheels, check that the
wheel nuts are tight after driving your vehicle the first
1600 km (1000 miles).
 If you have rotated, repaired, or changed your tires,
check that the wheel nuts are still tight after driving
1600 km (1000 miles).
 When using tire chains, be careful not to damage the
aluminum wheels.
 Use only the Lexus wheel nuts and wrench designed
for your aluminum wheels.
 When balancing your wheels, use only Lexus
balance weights or equivalent and a plastic or rubber
hammer.
 As with any wheel, periodically check your aluminum
wheels for damage. If damaged, replace
immediately.
