Recommended viscosity
SAE 5W-20 or 0W-20
SAE 5W-20 or 0W-20 engine oil
may be used. However, SAE 0W-
20 is the best choice for good fuel
economy and good starting in cold
weather.
■How to read oil container labels
The ILSAC (International Lubricant Standardization and Approval
Committee) Certification Mark is added to some oil containers to help
you select the oil you should use.

■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 frequent
acceleration and deceleration.
●A new engine consumes more oil.
●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.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per 1000
km)
●If you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles (1000 km),
contact your Lexus dealer.
■After changing the engi ne oil (U.S.A. only)
The oil change system should be reset. Perform the following procedures: Switch the display to the odometer. ( →P. 1 4 3 )
Turn the engine switch to the LOCK position.

While pressing the ODO/TRIP button, turn
the engine switch to the ON position. A mes-
sage MAINT REQD RESET MODE will
appear on the display. To select the system,
hold the button for at least 5 seconds. A mes-
sage COMPLETE will appear and a beep will
sound.STEP3

Oil viscosity
● The 0W 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 20 in 0W-20 indicates the oil viscosity when the oil is at 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 condition.
