This C1 oil is a high quality full synthetic lubricant for the use in gasoline and diesel engines of passenger cars, vans and light duty vehicles. This lubricant is based on the most advanced low SAPS technology with a minimum HTHS viscosity of 2.9 mPa.s. Meaning that this product can be particularly useful when low sulphated ash, phosphor and sulphur contents are required. It enhances the lifetime of the DPF and the TWC and maintains the high fuel economy rating of the engine. These oils have a typical lower viscosity in order to ensure optimal fuel consumption during short drives. Important: as these oils have the lowest SAPS technology, they are unsuitable for some engines. Consult the owners manual if in doubt.
