■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, since its pistons, piston rings and cylinder
walls have not become conditioned.
●Oil consumption: Max. 1. 1 qt./600 miles (1.0 L per 1000 km, 0.9 lmp.qt/600
miles).
