ENGINE BREAK-IN: ALL MODELS
Diesel propulsion systems require a pre-determined
"break in" period. During this time the engine should
not be run at a full load condition for extended periods.
Various engine load and speed conditions assist the inter-
nal engine parts such as bearings, valves and piston rings
to "seat" properly which will help ensure a longer engine
life. See operator's manual for further information.
During the "break in" period it is necessary to check the
engine oil more frequently since it is normal that the en-
gine will use more oil. If engine oil is required be sure to
check the engine manual for proper grade and viscosity.
Check the maintenance schedule in your engine owner's
manual and contact your Regal yacht dealer to set up
the fi rst maintenance inspection. Normally the engine
oil, fi lters, and drive oil inspections and maintenance are
performed during this inspection along with other items.
Never exceed a 12 month period between oil changes es-
pecially with diesel power since sulfur tends to enter the
lubrication system through the fuel combustion process
over a period of time.
OIL CHANGES (ENGINE & DRIVE)
Be sure to read the owner's manual regarding engine oil
change recommendations along with IPS stern drive oil.
Be sure to follow the Volvo recommended oil type and
viscosity. The engine oil change is an important factor
in obtaining engine longevity since impurities enter the
crankcase through the combustion process and build up
in the engine oil.
Be sure to check the drive oil on a periodic basis and
change it using the recommended type per the engine
owner's manual.
