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.
