Engine oil
Lubricating oils are specified by performance and quality classes. It is
usual for the specifications to be indicated according to the API (Amer-
ican Petroleum Institute) and ACEA (European Automobile Manufac-
turers Association).
Acceptable API oils: CH-4, CG-4, CI-4, CJ-4, DHD-1
Acceptable ACEA oils: E3-96, E4-07, E5-02, E7-04
Only use oil of a recognised brand to lubricate the engine. The choice
of a correct oil guarantees that the engine starts easily, because an oil
film remains on the cylinder walls and bearing surfaces. The friction is
low and so the starting rpm necessary for a dependable start can be
achieved with a lower starting torque. An incorrect choice of oil can
lead to a thickened oil layer on the cylinder walls and bearing surfac-
es. This can in turn lead to higher frictional resistance and more effort,
which forms a hindrance to reaching the starting rpm required for a
dependable start, and this results in a reduced lifespan.
Recommended lubricating oil viscosity
There are two important considerations when it comes to ambient
temperature in order to achieve satisfactory engine performance.
- the possibility to turn the engine over quickly enough to make an
easy start possible and
- adequate lubrication of internal wear surfaces during starting and
warming up.
By making the right choice of lubricating oil these requirements can
be met.
Because the viscosity (runniness) of lubricating oil varies with temper-
ature, the ambient temperature in which the engine is started deter-
mines the choice of viscosity class (SAE class).
To avoid having to change the oil for different seasons we recommend
SAE 15W-40 all-season motor oil.
For example:
Vetus Marine Diesel Engine Oil 15 W40
Shell Rimula R4 15W40
