The lifespan of an engine depends mainly on the quality of motor oil used. It’s therefore extremely important to make the right choice, which must be done by scrupulously following the manufacturer’s recommendations. The many and varied demands made of engine lubricants requires a great deal of expertise. Motor oil should cool, protect, prevent wear, remove dirt, last as long as possible and promote maximum engine power development. The day-to-day work of our chemists revolves around adapting motor oils to various new engine concepts by optimising lubricity, oil change intervals and fuel economy.
