An advanced synthetic-technology engine oil for passenger cars and commercial vehicles. Suitable for both gasoline and diesel engines in all types of modern vehicles. It is formulated with specially selected synthetic base oils that provide excellent resistance to oxidation and ageing, enabling extended oil-change intervals. ULTRA SYNTH 10W-40 protects the engine against wear, while helping prevent the accumulation of dirt and deposits. It significantly reduces engine friction and oil consumption. ULTRA SYNTH 10W-40 is particularly suitable for vehicles running on unleaded gasoline and is compatible with catalytic converters, without reducing their service life.
