60 Oil System
Oil Quality
Volvo Trucks North America, Inc. recog-
nizes 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 recom-
mended oil and oil filter change intervals.
Engines meeting the 2000 and 2001 emis-
sions requirements operate under higher
soot loading conditions than previous en-
gines. This has led Volvo to require a
higher grade oil that meets both API
CH-4 a
nd VDS-2 quality standards for
model year 2000 and 2001 Volvo engines.
This type oil is required for normal oil
intervals.
Normal grade engine oils for all engines
in vehicles produced by Volvo Trucks
North America, Inc. must meet or exceed
the API classifications CG-4 or CH-4.
VDS and VDS 2 are Volvo oil standards.
See page 61 for interval recommendations
for Volvo engines. See each other engine
manufacturer’s Operator’s Manual for infor-
mation on when and how to change the oil.
Oils that meet both API CH-4 a
nd VDS-2
are required for model year 2000 and 2001
Volvo engines. Most major oil companies
have oils that meet these specifications. A
list of approved oils can be found in Ser-
vice Bulletin 175–001, “
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 oils, graphitizers and friction reduc-
ing liquids are not necessary and may
even harm the engine.
