Oil Viscosity
Select viscosity for the ambient temperatures the vehicle
will be exposed to. It is not enough to just select the right
type of oil; the right oil viscosity is just as important.
The correct viscosity according to the SAE is determined
by the minimum ambient temperature at cold start
and the maximum ambient temperature during engine
operation. Use the temperature chart below to select the
best viscosity. In general, use the highest viscosity oil
available that still meets the cold start-up temperature
requirements.
W1000144
Select viscosity from the table above. Temperatures
refer to stable ambient temperature readings.
D12D and D16D Oil Type/Quality
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 this bulletin 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. Change all oil
filters at each oil change.
Synthetic oils do not allow further extension of oil drain
intervals. It is the contamination rate, i.e., soot, and the
depletion of additives, rather than base oil quality that
determines the useful engine oil life and therefore the oil
change intervals.
Note: Engines meeting the emissions requirements of
2004 operate under more severe conditions than previous
engines. This has lead Volvo to require an oil that meets
both VDS-2 and EO-N Premium Plus quality or both
VDS-2 and API CI-4 quality standards for model year
2003 through 2006 Volvo engines. Earlier engines also
work better with these oils. They are not required, but
are strongly recommended.
CAUTION
Extra oil additives must never be added to any oil
used.
