Maintenance and care
■Recommended viscosity
SAE 5W-30 is the best choice for 
good fuel economy and good 
star
ting 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 ILS
 AC 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.
