CAPACITIES (in litres)
Draining method.
Oil capacities are defined as below.
1/ Vehicle on horizontal ground (in the high position, if hydropneumatic suspension).
2/Engine warm (oil temperature 80°C).
3/Drain oil sump + remove filter cartidge (time for draining to last drops = 15 minutes).
4/ Refit drain plug + filter cartridge.
5/ Refill the engine.
6/ Start the engine (to allow the cartridge to fill).
7/Stop the engine(to allow oil to stabilise for 5 minutes).
ESSENTIAL : Systematically check the oil level using the oil dipstick.
