Engine Oil
Specifications
To help obtain optimum engine performance and to provide maximum protection, the engine requires engine oil with a rating of
HD‑SAE‑API CG‑4 and CH‑4.
We strongly recommend the use of the following oil that is a specially blended 15W‑40 oil with Marine Additives, for all
temperature operation. This oil exceeds requirements for API CH‑4, CF‑4, CG‑4 and CF‑2 oils.
Tube Ref No.
15W40 4-cycle Diesel

Engine Oil
Other recommended oils are listed in the following table. These oils are approved by Mercury Diesel and Marine Power Europe.
Shell Myrina
Mopar
For all‑temperature operation use 15W‑40 oil.
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.
Checking engine oil level must be done carefully. The oil level must be maintained between the minimum and the maximum oil
level mark on the dipstick. To ensure that you are not getting a false reading, observe the following before checking the oil
level.
•
If the boat is in the water, ensure that the boat is at rest.
•
If the boat is on a trailer, raise or lower the bow until the boat is sitting as it does at rest in the water.
•
Allow five minutes for the oil to drain into the oil pan if the engine has just been operated or oil has just been added.
Checking
IMPORTANT: Engine crankcase oil must be checked at intervals specified in Maintenance Schedules. It is normal for an
engine to use a certain amount of oil in the process of lubricating and cooling the engine. The amount of oil consumed depends
greatly upon engine speed, with consumption being highest at wide open throttle and decreasing substantially as engine speed
is reduced.
With the engine running, the crankshaft journals or rod journals may strike and break the dipstick, resulting in damage to
internal engine components. Stop the engine completely before removing or inserting the dipstick.

To check the engine oil level during operation, stop the engine and allow five minutes for the oil to drain into the pan.
