The ideal base for a long-lasting engine is high-quality oil. As engines become more and more advanced, the demands placed on the oil become higher and higher. The times when oil was used only to lubricate and cool are over. Nowadays it has to withstand high temperatures and pressures. It must also clean the engine of combustionresidue, abrasive wear, acids, water and fuelparticles. As if that wasn't enough, oil must ensure that the engine is sealed and protect it from corrosion.
