Maintenance and Service
Volvo Trucks North America recommends the viscosities shown in the
viscosity/temperature table for Volvo engines.
Oil Additives
Extra oil additives must never 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.
Using oils to the quality standards recommended in this manual makes the use
of extra oil additives unnecessary, as these oils already contain a balanced
treatment of additives.
Oil Consumption
Once the engine is stopped, check the oil level daily. If the engine has just
been stopped and it is warm, wait approximately five minutes to allow the oil
to drain back to the oil pan before checking. Add oil as necessary.
DO NOT overfill engine with oil.
