The main role of Polytron car oil is to prevent metal surfaces in the engine from coming into direct contact resulting in premature wear due to friction and heat generated in the combustion process. Once the engine is started, Polytron oil creates a very thin film between the moving components in the engine, causing them to "slip" properly, increasing its power, efficiency and performance. Use Polytron engine oil to protect against corrosion of engine components. Here you can find any type of Polytron car oil and the full range of oil and fuel additives .
