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 consumption, 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 Imp. qt./600 miles (1.0 L per 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 Lexus dealer.
