n Engine oil consumption
The amount of engine oil consumed depends on the oil viscosity, the
l
quality of the oil and the way the vehicle is driven.
More oil is consumed under driving conditions such as high speeds, fre-
l
quent acceleration and deceleration.
A new engine consumes more oil.
l
l 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 lmp. qt./600 miles (1.0 L per
l
1000 km). If the vehicle consumes more than this amount, contact your
Toyota dealer.
