Koyoto ESP SN series is an advanced technology fully synthetic high performance engine oils blended in severely refined fully synthetic basestocks fortified with sophisticated additive technology, specifically to provide extended oil drain intervals, save fuel consumption, protect antipollution systems and improve overall engine performance. It helps prolong the life and maintain the efficiency of Car Emission Reduction Systems in both diesel and gasoline powered automobile engines, with recent multi-valve engines equipped with turbochargers and direct injection fuel systems. Low content in Sulphated Ash, Phosphorus and Sulphur reduces particulate build up in Diesel Particulate Filters (DPF’s) and avoids poisoning of Gasoline Catalytic Converters (CAT’s).
