Why is it necessary to change oil filter during every car servicing?
Normal engine oil consists of micro particles which are smaller than 1/100 micro and move around freely. As the particles come into contact with oxide, carbon or sulphuric acid, they will grow into bigger particles. As the particles become bigger, their viscosity also increases, making them impossible to pass through the oil filter, thus causing the filter to lose its effect. As we can see, normal engine oil is unable to maintain its performance in this aspect. Unlike normal engine oil whose particles are 100A, TOHO ENGINE OIL oil particles are 3A and 5A and also it has strong resistant to oxidization and high cleansing capabilities, which separates the micro particles from the oxide and carbon, thus preventing the particles from growing bigger, enabling the oil to go through the oil filter easily, displaying its superior quality. TOHO ENGINE OIL is able to maintaining the diameter of each micro particle smaller than on micron, thus prolonging the lifespan of oil filter. Therefore by u
