How to renew the lubricating oil of the
engine
Warning! Discard the used lubricating oil in a safe
place and in accordance with local regulations.
Warning! All these engines are tted with a ‘closed’
crankcase breather system.
Any necessary oil additions to the sump must be
carried out with the engine stationary.
Under no circumstances must oil additions be
carried out with an engine running as oil could enter
the ‘closed’ crankcase breather system causing the
engine speed to increase rapidly without control.
It is important to ensure the correct level of
lubricating oil is not exceeded in the sump. If there is
too much oil in the sump the excess must be drained
to the correct level. An excess of engine oil in the
sump can enter the ‘closed’ crankcase breather
system, which could cause the engine speed to
increase rapidly without control.
1. Connect a suitable hose to the outlet of the sump
drain pump (A1). Put the free end of the hose
into a suitable container with a capacity of at
least 18 litres (32 UK pints) 19 US quarts. Use
the drain pump to empty the sump. If possible,
the lubricating oil should be drained while it is still
hot.
2. Clean the area around the ller cap on top of the
rocker cover. Remove the cap and add slowly
approximately: For 6 cylinder engines 15 litres
(26.4 UK pints) 15.8 US quarts, for 4 cylinder
engines 8,1 litres (14.25 UK pints) 8.5 US quarts
of new and clean lubricating oil of an approved
specication (see page 44) to the engine. Allow
the oil enough time to pass to the sump. Remove
the dipstick (B1) for 6 cylinder engines or (C1)
for four cylinder engines and ensure that the
lubricating oil is to the full mark (B2) or (C2). Do
not exceed the full mark on the dipstick. Fit the
ller cap and ensure that the dipstick is tted
correctly in the dipstick tube.
Note: Renew the lter canisters when the lubricating
oil is renewed.
