Operation; Engine Break-In Period - Volvo Penta DPX 500 Instruction Book

Engine break-in period _________________________________________________________

Note: To ensure proper lubrication during the break-in period, do not remove factory break-in oil until after the 20-hour
break-in is completed. The First Service inspection should be carried out after 20 hours of operation.
Failure to follow engine break-in procedures can result in serious engine damage.
Never run an engine at a constant engine speed for long periods during the break-in period.
All Volvo Penta engines have been run for a short time during a final test at the factory. You must follow the engine
break-in procedure during the first 20 hours of operation to ensure maximum performance and longest engine life.
During the break-in period, watch out for the following items during the initial engine run:
1. Check engine oil level frequently.
Be sure to check the oil level frequently during the first 50 hours of operation, since some oil consumption
may be noticed until the piston rings are properly seated.
The engine may use more engine oil during the running-in period than would otherwise be normal. Check the oil
level regularly and more frequently during the running-in period.
•
Maintain oil level in the safe range, between the ADD and FULL marks on dipstick. Somewhat higher oil
consumption is normal until the piston rings have seated.
•
If you have a problem getting a good oil level reading on the dipstick, rotate the dipstick 180° in the
dipstick tube.
•
When adding engine oil, use Mobil 1 (15-50W) synthetic engine oil for gasoline engines.
•
Note: To ensure proper lubrication during the break-in period, do not remove factory break-in oil until
after the 20-hour break-in is completed.
2. Watch the oil pressure gauge.
•
Oil pressure will rise as RPM increases, and fall as RPM decreases. In addition, cold oil will generally
show higher oil pressure for any specific RPM than hot oil. Both of these conditions reflect normal engine

operation.

•
If the oil indicator fluctuates when the boat is turning, climbing on plane, etc., the oil pickup screen may
not be covered with oil. Check the oil dipstick. If required add oil, but do not overfill. If the oil level is
correct and the condition persists, ask your Volvo Penta dealer to check for possible gauge or oil pump
malfunction.
3. Watch the engine temperature indicator to be sure there is proper water circulation.
Failure to follow the break-in procedure may void the engine warranty.
