Extremely high level of engine protection, ensuring that all engine parts last for a long time. Protection is greater than 20% at the official European manufacturers’ wear tests. Protection for petrol engine pollution-control systems: optimises the way in which three-way catalytic converters work, preventing them from getting clogged up with deposits. Reduces emissions of NOx, HC and CO in particular. Engine cleanliness: offers the best possible protection against deposits as soon as the engine is started, during cold starts and at extremely high temperatures. Engine start-ups easier - at both very low and very high temperatures (ideal for stop&start systems, for example). Its resistance to lubricant ageing is 35% higher than official requirements after oxidation test.
