LUBRICATING OIL

The engine is delivered from the factory filled with an approved engine oil.
The use of non-approved engine oils could affect warranty rights,
and cause engine damage.
To ensure long and trouble-free service, it is important to select oil of the correct viscosity
and service designation. Only multigrade oils of American Petroleum Institute (API) service
designation CH-4 will achieve proper performance. Look for the service mark printed on the oil
container. See Figure 5-1.
Figure 5-1
When maintenance work is performed, record engine oil changes including details of the brand
used, the quality category, and the Society of Automotive Engineers (SAE) viscosity rating of the
oil. When topping off, use only engine oils of the correct API designation and SAE rating.
5.2.1
Synthetic oil may be used in MBE 4000 engines, provided they are of the correct API designation
and viscosity, as required for non-synthetic oil.
Synthetic oil offers improved low-temperature flow properties and high-temperature resistance to
oxidation. However, it is generally more costly than non-synthetic oil.
