SAE 15W/40 oil is recommended for use in severe driving conditions that increase oil consumption and
raise oil temperatures (e.g. mountain driving with frequent decelerations, or fast highway driving). Note,
however, the higher temperature range of 15W/40 oil.
Volvo recommends the use of fuel-economy-improving oils. When using these oils, the Volvo
recommended oil change intervals must be followed.
Synthetic or semisynthetic oils may be used if their specifications comply with the oil quality
requirements.
Volvo does not recommend additional oil additives, as they can adversely affect the engine.
