You should change the engine oil and oil filter after
approx. 100 hours of operation, or at least once
per season.
Choose Volvo Penta engine oil which has good
inhibiting qualities and you will not need to add
any special inhibiting oil for a normal winter lay-up.
A new oil filter will remove soot and metal particles
from the oil and prevent unnecessary engine wear.
Genuine Volvo Penta filters are tested and specially
designed to suit each particular engine type.
Run the engine warm before changing
the oil. It is easier to do this when the
boat is still in the water (it can also be
done in connection with engine inhibiting).
Switch off the engine and use an oil bilge pump to
pump out all the engine oil through the dipstick hole.
Change the oil filter and fill up with the right amount
of Volvo Penta engine oil. Also change transmission
oil, please refer to the ”Oil changes – drive/reverse
gear” chapter. Run the engine for a while. Check for
oil leaks.
