Alpine RSD 10W-40 is a semi-synthetic high-performance low-friction oil for passenger car diesel engines. It is a class SAE 10W-40 product.
Its base oil composition combines the advantages of modern refinery products with those of synthetic components.
The base oil composition and shear resistant VI enhancers ensure that the product retains its specified viscosity properties during the entire lubrication time.
The ageing process of this engine oil is well managed over the permissible maximum oil change interval. Antioxidants and cleaning additives prevent deposits, keep pistons and valves clean and protect the engine against cold sludge. The low friction loss in the engine significantly reduces fuel consumption and emissions. Low evaporation loss prevents deposits in valves, sludging and laking, so that pistons and piston ring grooves are kept clean.
Alpine RSD 10W-40 is recommended for use in all passenger car diesel engines including models with diesel turbochargers and catalytic converters.
