ENGINE OIL CONSUMPTION
Max engine oil consumption is usually 400 grams every
1000 km.
When the car is new, the engine needs to run in,
therefore the engine oil consumption can only be
considered stabilised after the first 5000 ÷ 6000 km.
WARNING
214
When the engine is hot, take care when working inside the engine compartment to
avoid burns. Remember that when the engine is hot, the fan may cut in: danger of
injury. Scarves, ties and other loose clothing might be pulled by moving parts.
IMPORTANT The oil consumption depends on driving
style and the conditions under which the car is used.
