Carlube's Triple R Advance formula is designed for modern vehicles, with synthetic technology that bonds the oil to the engine's surfaces, reducing friction, wear, and providing exceptional all-year-round protection from cold start to high-temperature driving. This oil is suitable for both petrol and diesel engines, with a lower ash content that helps reduce particle build-up, consequently reducing environmental impact through reduced emissions. This formula is suitable for use on most high-performance engines. It is a 5W-40 fully synthetic motor oil. Key Features: ACEA: C3 API: SP OEM: MB229.31, Fiat 9.55535-S2 Lower ash content helps reduce particulate build-up in the DPF Protects the engine surface whilst staying in grade throughout a wide temperature range Reduces the need for top-up through lower evaporation at high temperatures Lower sulphur & phosphorus content reduce poisoning of Gasoline Catalytic Converters. It all started in 1988 when Clifford Schofield, the father of cutting compounds, decided to expand Tetrosyl into the lubrication sector with his new brand Carlube. Within just 30 years of trading and more products added to The brand, Carlube has grown to become the largest independent oil manufacturer in the UK with all production taking place at our state-of-the-art manufacturing facility in the Northwest of England. Since the launch of Carlube's first product in 1988, our Formula 1 Non-Spec Oil, we have evolved and grown to be capable of producing all the lubricant requirements from standard mineral oils right through to fully synthetic high performance racing oils.
