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. Typical API Symbol 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 reducing liquids are not necessary and may even harm the engine. 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 and VDS-2 are required for model year 2002 Volvo engines. Most major oil companies have oils that meet these specifications.
