Lubricants for four-stroke engines 07

Selection of viscosity grades

Selection of the viscosity grade is based primarily on the ambient temperature at which the engine

is to be started and operated. If the relevant performance criteria are observed the engines can be

operated both with single grade and multigrade oils, depending on the application. Standard values

for the temperature limits in each viscosity grade are shown in Chart 1.

If the prevailing temperature is too low, the engine oil must be preheated.

Oil drain intervals for diesel engines

Engine oil drain intervals depend on the engine-oil quality, its conditioning, the operating conditions and the fuel used.

The intervals quoted (Table 3) are guidelines based on operational experience and are valid

for applications with a standard load pro ﬁle.

Oil d rain intervals (Table 3)

= To be used in conjunction with fuels with max. 500 mg/kg sulfur content.

The oil drain intervals in the table are recommended guidelines when using diesel fuels with < 0.5%

sulfur content. The limit values speciﬁed in Table 4 for used oil must be complied with. The numbers of

operating hours quoted for oils must be con ﬁ rmed by means of oil analysis.
