■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy, and good
starting in cold weather.
*: If SAE 5W-30 oil is not available,SAE 10W-30 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
■ 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 fre-
quent 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 the vehicle consumes more than this amount, contact your Lexus dealer.
■Resetting the engine oil maintenance data (U.S.A. only)
Perform the following steps:Switch the display to the odometer. ( →P. 1 2 6 )
Turn the engine switch to the “LOCK” position.
Turn the engine switch to the “ON” position with the trip meter reset but-
ton held down.
