GENERAL
ENGINE OIL CONSUMPTION
I-Oil consumption depends on:
- The engine type.
- How run-in or worn it is.
- The type of oil used.
- The driving conditions.
II -An engine can be considered RUN-INafter:
- 3 000 miles (5 000 km)for a PETROLengine.
- 6 000 miles (10 000 km)for a DIESELengine.
III - MAXIMUM PERMISSIBLEoil consumption for a RUN-INengine.
- 0.5 litresper 600 miles (1 000 km)for a PETROLengine.
- 1 litreper 600 miles (1 000 km)for a DIESELengine.
DO NOT INTERVENE BELOW THESE VALUES.
IV - OIL LEVEL:The level should NEVERbe above the MAX.mark on the dipstick after changing or topping up the oil.
- This excess oil will be used up rapidly.
- It will reduce the engine output and adversely affect the operation of the air circuits and gas recycling.
