ENGINE OIL
Oil Consumption
Just because an engine uses oil does not mean it is not
healthy or it is defective. A marine engine gets worked
very hard compared to an automobile engine. When
you are cruising down the highway in your car, once
it gets up to speed it only takes a small amount of the
engine’s power (around 20 HP) to maintain the speed
of the vehicle on a flat road. A boat, on the other hand,
is utilizing a significantly larger amount of the engine’s
output to keep the boat moving. Then add the extra load
of ballast bags and a wakeboarder, surfer or skier and
we are utilizing even more of the engine’s capacity. The
harder you work the engine, the more consumables
(gasoline and oil) it needs to keep running. As long as
there are not other detrimental operating characteristics
such as low power, oil fouled plugs, constant smoking,
etc., do not be concerned if the engine uses some oil ...
it’s the nature of the beast.
