Motor oil for use in extreme conditions. It provides uninterrupted lubrication in the most extreme operating conditions, i.e. in low temperatures (cold start) and in high temperatures with the engine heated to the maximum, while retaining exceptional stability, thus engaging the full power in all driving conditions. It is designed for lubricating extremely loaded gasoline and supercharged diesel engines with catalytic converters. A special oil formulation provides complete engine protection in extreme sports driving conditions. The oil, besides its use in motor sports, can be employed by the drivers of modern cars who like to “floor it” but, at the same time, require maximum engine protection. Ready to be mixed with other branded motor oils of this kind.
