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. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/
●
1000 km)
If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600
●
miles (1000 km), contact your Toyota dealer.
