Engine Oil

Specifications

To optimize the performance of this engine in marine applications, Mercury strongly recommends the use of Quicksilver 5W‑30
Full Synthetic TDI Engine Oil. This oil meets international ACEA C3 specifications.
2.0L
Engine oil (with filter)
Oil Level—Overfilled
Discharge of oil, coolant, or other engine/drive fluids into the environment is restricted by law. Use caution not to spill oil,
coolant, or other fluids into the environment when using or servicing your boat. Be aware of the local restrictions governing
the disposal or recycling of waste, and contain and dispose of fluids as required.
An overfilled engine crankcase or block can cause a fluctuation or drop in oil pressure. The overfull condition results in the
engine crankshaft splashing and agitating the oil, causing it to become aerated. The aerated oil causes a loss of engine
performance and an increase in crankcase back pressure. An extreme overfill condition could result in large amounts of oil
being drawn into the intake.
