Lubrication system

The engine has a pressurized lubrication system. The oil pump sucks oil from the oil pan and then pumps it to the moving parts in the engine. The oil is cooled in the oil cooler (not all models) and cleaned in the oil filter. Always use Volvo Penta original oil filters, they have an integral relief valve that allows the oil to by-pass the filter even if the filter is completely clogged.

IMPORTANT With a new or reconditioned engine, the oil and oil filters must be changed after 20-50 hours of operation. After that they should be changed every 100 operating hours or at least once a year. Use only oils of the recommended grade: See chapter Technical Data.

Every day before starting check that the level is between the Max and Min markings on the dipstick (A) and that the level is sufficient for the planned journey. Top up if necessary through the oil filler (B). See chapter Technical Data for the grade of oil. High performance engines usually have a higher oil consumption than lower powered engines. Apart from lubrication, the most important function of the oil is to cool and remove heat from the internal components of the engine. High performance engines produce much more heat at full load than lower powered engines. So it is important that the correct oil level is always maintained. Check oil level daily.

IMPORTANT Fill to the Max mark and no higher. The level must not drop below the Min mark.

Oil and oil filters. Replacement

The oil should be changed when the engine is hot. Stop the engine. Suck out oil through the oil scavenging/bilge pipe.

WARNING! Hot oil can cause burns.

Unscrew the old filter. NOTE! Avoid oil spillage. Check the mating surface of the engine is clean. Moisten the filter rubber gasket with a little oil. Screw on the new filter by hand until it is in contact with the mating surface. And then a further half turn but no

more!

Top up oil to correct level. Start the engine and let it idle. Stop the engine. Check that there are no leaks round the oil filter and the oil level, top up if necessary. See chapter Technical Data for the grade of oil.

NOTE! Collect up the old oil and filter for deposit at a proper disposal site.
