NOTE 
Oil filters should always be changed when 
changing the oil.
 
1.3.4 Oil Filters 
There are three filters on the engine, one of 
which is a bypass filter. This should be changed 
at the same time as the full-flow filter(s). 
 
CAUTION 
Volvo branded oil filters are designed to 
provide the proper level of filtration and 
protection for Volvo engines. Filters that do 
not meet the same stringent requirements 
may void engine warranty. 
 
 
FIGURE 3: D13F OIL FILTERS 
1.3.5 Synthetic Lubrication 
Synthetic oils are offered by some oil suppliers 
as an alternative to the traditional, petroleum 
based oils for engines. These oils may be used 
in Volvo engines, provided they meet the quality 
levels specified on the previous pages, that is: 
both VDS-4 and EO-O Premium Plus. 
The use of synthetic oils does not permit the 
extension of the recommended oil change 
intervals.
 
1.3.6 Oil Viscosity 
The viscosity grade defines the thickness of the 
oil. The oil must be thin enough at low 
temperatures for easy cold starts and thick 
enough to protect at high temperatures. An oil is 
not fully defined until both the API quality 
classification and the viscosity grade are 
specified. 
Choose the viscosity grade for the typical 
ambient temperature for the application. 
Multigrade oils have a broad range that suit 
operation in changing temperature. 
Volvo North America recommends the 
viscosities shown in the viscosity/temperature 
table for Volvo engines. 
 
1.3.7 Oil Additives 
CAUTION 
Extra oil additives must never be added to 
any engine oil used. Additives such as break-
in oils, top oils, graphitizers, and friction 
reducing liquids are not necessary and may 
even harm the engine. 
Using oils to the quality standards 
recommended in this manual makes the use of 
extra oil additives unnecessary, as these oils 
already contain a balanced treatment of 
additives. 
1.3.8 Oil Consumption 
Once the engine is stopped, check the oil level 
daily. If the engine has just been stopped and it 
is warm, wait approximately five minutes to allow 
the oil to drain back to the oil pan before 
checking. Add oil as necessary. 
CAUTION 
DO NOT overfill engine with oil. 
All diesel engines are designed to consume 
some oil, so it is normal to add oil periodically. 
An engine used in heavy-duty operation will 
consume more oil than one in normal operation.
