Volvo XC90: Specifications / Transmission fluid specifications
Under normal driving conditions, the transmission fluid will not need to be
changed during the transmission's service life. However, it may need to be changed
if the vehicle is driven frequently in adverse driving conditions.

Engine oil of type VCC RBS0-2AE 0W-20 must be used. Lower oil grades may not
offer the same fuel economy, engine performance or engine protection.
