Engine internal parts, through the lubrication of oil to achieve its normal work.When the engine running, there will cause some metal debris, dust and water vapor to mix with the oil. After a long time,  it will reduce oil life or even affect the normal operation of the engine.

The main function for oil filter is to filter the dust in the oil, make the oil clean, prolong its normal lifetime. Through the filtering by filter, it’s reduce the wear and make it work efficiency for engine.

There is a standard when to choose the oil filter. We’d better buy the oil filter according to its standard and choose the suitable one.

The standards to choose oil filter

Filtration accuracy: The filter can filter out all the 30um particles, and meet the protection of the engine to reduce wear requirements

The filter reduces the amount of particles entering the lubrication gap and causing wear

The oil flow meets the engine oil demand

Filter replacement cycle is long, at least longer than the life of the oil

Large amount of filter capacity ash  can be suitable for harsh environments

Filter high temperature and corrosion resistance

The lower the differential pressure is, the better the oil filter is

At present, most cars use a spin-on oil filter.  The filter is not removable and washable disposable filter, the replacement of oil must also replace the oil filter. Generally every 5,000 km to be replaced oil and oil filter.
