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. 1.0 L per 1000 km (1.1 qt./600 miles, 0.9 Imp.
qt./600 miles)
If your vehicle consumes more than 1.0 L (1.1 qt., 0.9 Imp. qt.) every
1000 km (600 miles), contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
CAUTION
Used engine oil
Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground.
Call any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, service station or auto parts store for information
concerning recycling or disposal.
Do not leave used engine oil within the reach of children.

6-1. Specifications
IS F_EERecommended viscosity (SAE):
SAE 5W-30 is filled into your
Lexus vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures,
the engine may become diffi-
cult to start, so SAE 5W-30
engine oil is recommended.
Oil viscosity (5W-30 is explained here as an example):
• The 5W in 5W-30 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 viscosity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is oper-
ated at high speeds, or under extreme load conditions.
