Gasolines quality
In a very few cases, you may experience driveability
problems caused by the particular gasoline that you are
using. If you continue to have unacceptable driveability,
try changing gasoline brands. If that does not rectify
your problem, then consult your Lexus dealer.
NOTICE
Do not use gasohol other than stated above. It will cause fuel system damage or vehicleperformance problems.
If drivability problems are encountered (poorhot starting, vaporizing, engine knock, etc.),discontinue its use.
Take care not to spill gasohol during refueling.Gasohol may cause paint damage.

FACTS ABOUT ENGINE OIL CONSUMPTION
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.

ENGINE
376The 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.
Importance of engine oil level check
One of the most important points in proper vehicle
maintenance is to keep the engine oil at the optimum
level so that oil function will not be impaired. Therefore,
it is essential that the oil level be checked regularly.
Lexus 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
ºChecking the engine oil levelº on page 378.

USED ENGINE OIL
CAUTION
Used engine oil contains potentially harmful
contaminants which may cause skin disorders such
as inflammation or skin cancer, so care should be
taken to avoid prolonged and repeated contact with
it. To remove used engine oil from your skin, wash
thoroughly with soap and water.
 Do not leave used oil within the reach of children.
 Dispose of used oil and used oil filters only in a safe
and acceptable manner. Do not dispose of used oil
and used oil filters in household trash, in sewers or
onto the ground. Call your Lexus dealer or a service
station for information concerning recycling or
disposal.

CHECKING THE ENGINE OILLEVEL
62E001a
With the engine at operating temperature and turned
off, check the oil level on the dipstick.
1. To get a true reading, the vehicle should be on a level
spot. After turning off the engine, wait a few minutes for
the oil to drain back into the bottom of the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick and push it in as far as it will go,
or the reading will not be correct.

4. Pull the dipstick out and look at the oil level on the end.
If it is between the full line ( 5 ) and the low line ( 4 ),
it is O.K.

ENGINE
381
If the oil level is below or only slightly above the low
line,
add engine oil of the same type as already in the
engine.
Remove the oil filler cap and add engine oil a little at a
time, checking the dipstick. The approximate quantity of
oil needed to fill between the low line and the full line on
the dipstick is indicated below for reference.
When the level reaches within the correct range, return
the filler cap and turn the cap clockwise until you hear a
click.

NOTICE
Avoid overfilling, or the engine could be
damaged. C heck the oil level on the dipstick once
again after adding the oil.

Engine oil selection
Use API SJ, ºEnergy±Conservingº multigrade engine oil
or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
62L005±1
Temperature range anticipated before next oil change
SAE 5W±30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold
weather.
If you use SAE 10W±30 engine oil in extremely low
temperatures, the engine may become difficult to
start, so SAE 5W±30 engine oil is recommended.
