■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
*: If SAE 5W-30 is not available,SAE 10W-30 may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
■ How to read oil container labels
Some oil containers are labeled wi th ILSAC certification marks that
help you to select the proper oil.

■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumpt ion, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per 1000
km). If the vehicle consumes more than this amount, contact your Lexus dealer.
■Resetting the engine oil main tenance data (U.S.A. only)
Perform the following steps: Switch the display to the odometer. ( P. 1 0 3 )
Turn the ignition switch to the “LOCK” position.
Turn the ignition switch to the “ON” position with the trip meter reset but-
ton held down.
Keep pressing the knob until th e “MAINT REQD” light goes off.
If the light continues flashing, return to STEP 1 and try again.

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity:
● The 5W 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.
● The 30 in 5W-30 indicates the oil viscosity when the oil is as 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.
