Engine Oil; Oil Quality; Oil Change Intervals; Oil Filters - PREVOST H3-41 Maintenance Manual

NOTE
For maintenance or repair of engine components or engine-related components, please refer to Volvo
Trucks North America Web Site under: Parts & Service, purchase engine literature, D13H engine.

2.3 ENGINE OIL

Keep the engine oil at the proper level and
change it at the recommended intervals. Always
replace the oil filters at the same time as when
the oil is changed.

2.3.1 Oil Quality

Volvo North America recognizes engine oils that
meet or exceed the standards given by
American Petroleum Institute (API) for the oil
classifications listed in this manual. Only oils
licensed to carry the API symbol should be used.
Lubricants meeting API standards have provided
maximum engine life when used together with
the recommended oil and oil filter change
intervals.
VDS-4 diesel engine oil is mandatory for use in
all 2010 emission compliant Volvo engines.
These engines, which can be identified by the
presence of a DEF tank and an exhaust
aftertreatment system using Selective Catalytic
Reduction (SCR), also require the use of Ultra
Low Sulfur Diesel (ULSD) fuel. VDS-4 oils
exceed the new API service category CJ-4.
CAUTION
DO NOT add extra oil additives. Additives such
as break-in oils, top oils, graphitizers, and
friction-reducing liquids are not necessary and
can harm the engine.

2.3.2 Oil Change Intervals

The length of time an engine can operate before
an oil change depends on the quality oil used,
the type of fuel used, fuel consumption, engine
oil consumption, vehicle application, level of dust
in the air, and fuel consumption. The change
intervals given in the Lubrication And Servicing
Schedule are maximum intervals. If the vehicle is
operating in heavy-duty operation, dusty or off-
road conditions, etc., reduce the intervals for
more frequent oil changes.
Engine oil and filters change
Change engine oil and filters at the intervals
specified by the Lubrication And Servicing
Schedule in Section 24: LUBRICATION &
SERVICING.

Use the information in the table below to

NOTE: If idle time is greater than 25%, use the

Lubrication and Servicing).
NOTE
Oil filters should always be changed when
changing the oil.

2.3.3 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).
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.
