Suitable Engine Oil Grade
It is recommended that only genuine BMW specification engine oils are used in
a Morgan Plus Four. Engine oils with the following oil specification can be used
to top up if required:
ACEA A2/B2 or ACEA A2/B3 or ACEA A3/B3 Fully Synthetic engine oil of the
highest possible quality. Viscosity Class SAE 5W-30.
Oil Change
WARNING Engine oil not replaced in time can lead to increased engine
wear and / or engine damage. Do not exceed the service date indicated.
Morgan recommends having the engine oil changed by a certified Morgan
Dealership or specialist workshop.
The engine oil should be changed every 10,000 miles or annually. Run the engine to
normal temperature. Switch off the engine and remove drain plug from the sump.
When the oil has drained completely, clean and replace the plug with a new plug
gasket. Fit a new oil filter and fill with 5.25 litres (1.4 US Gal) of the correct grade
and quantity of oil. Replace the filler cap on the rocker cover and run the engine for
a short while. Take an oil level reading. The level should be on the 4/4 or 5/4 mark.
If the reading is below the 4/4 mark, top up with appropriate oil (see Suitable
Engine Oil Grade). For every 1/4 mark below 4/4 add 0.25 litre of engine oil.
WARNING Never over-fill an engine with oil.
WARNING Care should be taken when draining engine oil, as it may be very hot.
WARNING Prolonged exposure to used engine oil can cause serious skin
disorders. Avoid excessive contact with skin or use protection.
WARNING The radiator fan may operate even when the ignition is switched
off. Take care not to work near the fan until the engine has cooled sufficiently.
Oil Filter
The Morgan Plus Four uses a replaceable oil filter element located in the middle
of the left-hand side of the engine which should always be replaced when the
engine oil is changed.
To remove the filter, unscrew the filter cover anti clockwise and carefully
withdraw from the vehicle taking care to catch any dripping oil. Install the new
filter into the housing on the side of the engine noting its correct orientation.
Remove the old seal from the filter cover and clean off any old engine oil, fit a
new seal and lightly lubricate with clean engine oil. Screw the cover on clockwise
until fully seated taking care not to over tighten.
Gearbox
The transmission system is permanently filled. The transmission oil level should
be checked by a Morgan Service Dealer during routine servicing.
Air Cleaner
The injection system fitted to this car detects the level of air drawn into the
engine, and uses this information to control the fuel level. It is most important
that the airflow is not restricted. The air cleaner should be changed every 10,000
miles, or more frequently in dusty conditions or regular town use. A Morgan
Service Dealer should change the air filter element as it is only accessible from
underneath the vehicle. When replacing, use the correct specification of element.
Spark Plugs
The spark plugs should be checked every 10,000 miles for the correct gap. The
electrode and body should be cleaned and examined for damage. If the plug
shows any sign of damage or deposits it must be replaced. When fitting new
spark plugs be sure only the correct specification is used and the gap correctly set.
