Engine Lubrication System

Whenever two components rub together, friction
causes wear on both components. To minimize the
wear on your engine, a lubrication system has been
put in place to help components slide next to each
other easier. This is particularly important within
the inner workings of an engine. It is important to
ensure your lubrication system is working properly
at all times.
Your Regal utilizes lubrication and fl uids that need
regular check ups. Refer to your engine owner's
manual for specifi c details regarding the proper
maintenance of the lubrication system.
Note that your engine uses other lubricants in addition
to engine oil such as power trim fl uid and gear
lubricants to reduce wear on moving components.
These fl uids should be checked according to
the recommended
determined by the engine manufacturer.

Engine Oil

The purpose of engine oil is to lubricate the
internal components of the engine and ensure
parts that regularly move against each other have
reduced friction to lessen wear and noise between
components. An oil fi lter keeps metal particles
and water out of the engine's interior.
Stern drive engines performing on regular oil
should have the oil drained and replaced after the
fi rst 20 hours of operation or 3 months, and every
100 hours or at 1 year intervals thereafter.
