Oil System 61
Oil Quality
Volvo Trucks North America, Inc.
recognizes and recommends 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.
Engines meeting the emission
requirements valid from October
2002 operate under higher soot loading
conditions than previous engines. This has
led Volvo to require a higher grade oil that
meets both VDS-2 and EO-N Premium
Plus (for extended oil drain interval) or
VDS-2 and CI-4 (for normal oil drain
intervals) quality standards intervals.
Normal grade engine oils for all engines in
vehicles produced by Volvo Trucks North
America, Inc. must meet or exceed the
API classifications CI-4 VDS-2 is Volvo oil
standard.
See page 62 and page 63 for interval
recommendations for Volvo engines. See
each other engine manufacturer’s Operator’s
Manual for information on when and how
to change the oil.
Oils that meet both CI-4 a
nd VDS-2 are
required for model year 2002 Volvo engines.
Most major oil companies have oils that meet
these specifications. A list of approved oils
can be found in Service Information group
17 “Oil and Filter Change Intervals.”

CAUTION
Extra oil additives must not under any
circumstances be added to any engine oil
used. Additives such as break-in oils, top

liquids are not necessary and may even
harm the engine.
