Oil consumption
10
TESTING METHOD
Oil consumption of 1 litre for 1 000 km (620
miles) is acceptable.
Check there is no external oil leak from the en-
gine.
For accurate testing, certain conditions must be
observed when draining the engine oil :
- the engine should be warm,
- the dipstick and filling plug should be removed.
Drain the engine and leave the oil running out for
15 minutes minimum.
Refit the drain plug and "seal" it (spot of paint co-
vering the plug and the sump) in order to check at
a later date that it has not been removed.
Use a measuring cylinder to check the amount of
oil required to fill the engine:
Engines:
E7J 2.75 litres
K7M 3 litres
F3R 5.5 litres
F8Q 5 litres
Refit the filling plug and seal it.Ask the driver to return the vehicle after 1 000 km
(620 miles) during which time the oil level should
be monitored regularly with the dipstick.
When the vehicle is returned, check the drain and
filling plugs have not been tampered with.
Under the same conditions:
- engine warm,
- dipstick and filling plug removed.
Drain the oil and use a measuring cylinder to
check the amount of oil collected.
Calculate the oil consumption in litres per
1 000 km (620 miles) if the mileage is different.
