If there are too many impurities and grease stains in the oil, they will stick to the filter paper and block the filter holes, causing the oil pressure to become low. It is time to change the filter at this time;
5. The general machine filter and oil can be replaced together. If it is mineral oil, yellow shell, Speedmaster, the machine filter replacement cycle is 6 months, and the mileage cycle is 5000km;
