Carlube Triple R 5W40 fully synthetic diesel engine oil is specially formulated for use in Volkswagen, Audi, Seat and Skoda diesel cars and light vans fitted with a pumpe duse (PD) engine - Specification VW 505.01. The ultimate in engine protection for all driving conditions. Carlube Triple R Motor Oil  has developed a range of semi synthetic and fully synthetic motor oil to meet the latest API and ACEA requirements. Triple R also incorporates a range of low ash/low SAPS fully synthetic engine oils to meet the requirements of the latest generation vehicles with exhaust after treatment devices. Low SAPS (low sulphated ash, phosphorus & sulphur) engine oils are safe for catalytic converters & diesel particulate filters (DPF s). Detergents in standard engine oils can form ash on combustion which can lead to the DPF becoming clogged up by soot, damaging the filter & impairing engine and emissions performance. So it is essential that low SAPS engine oils are used for diesel & petrol vehicles with exhaust treatment systems.
