Gasolines containing alcohol
Gasohol is a mixture of gasoline and ethanol. If you use
gasohol in your Lexus, be sure that it is unleaded, has an
octane rating no lower than 87 and does not contain more
than 10% ethanol. Lexus does not recommend the use of
gasolines containing methanol.
If you use gasoline containing methanol, use only gasoline
meeting the requirements above and also containing less than
5% methanol with cosolvents and corrosion inhibitors for
methanol.
NOTICE:
Do not use gasohol other than stated above. It will
cause fuel system damage or vehicle performance
problems.
If drivability problems are encountered (poor hot
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.

CHECKING THE ENGINE OIL
LEVEL
Low line
Add oilO.K.Too full
Full line
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 and the low line, it is O.K
If the oil level is below or only slightly above the low line,
add engine oil of the same types as already in the engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. The appropriate 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.
Check the oil level on the dipstick once again after
adding the oil.

Engine oil selection
Use API grade SG, Energy-Conserving II multigrade engine
oil. Recommended viscosity is as follows.

CHECKING THE ENGINE
COOLANT LEVEL
“FULL” line
“LOW” line
Look at the see-through coolant reservoir tank. The
coolant level is satisfactory if it is between the “FULL” and
“LOW” lines on the tank. If the level is low, add
ethylene-glycol type coolant.
The coolant level in the reservoir tank will vary with engine
temperature. However, if the level is on or below the “LOW”
line, add coolant to bring the level up to the “FULL” line.
Use only ethylene-glycol type coolant. For information on
ethylene-glycol coolant, see also “Coolant type selection” on
page 170.
If the coolant level drops within a short time after replenishing,
there may be a leak in the system. Visually check the radiator,
hoses, radiator cap, drain cocks, and water pump.
