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 accu-
rately.
Oil consumption: Max. 1.0 L/1000 km (1.1 qt./600 miles, 0.9 Imp. qt./600
miles)
If your vehicle consume more than 1.0 L (1.1 qt., 0.9 Imp. qt.) every 1000
km (600 miles), contact any authorized Toyota 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 Toyota 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.
