Oil filters

The matter is that engine oil, greasing the engine, constantly becomes soiled. First, the working engine is exposed to huge loadings and microparticles fall off it from time to time. It is called wear. Also, dust can get to the engine together with air. Besides, even qualitative fuel at combustion forms soot. All this charm, of course, gets to oil which instead of greasing of the engine begins to work as some kind of emery paper. As a result - the car rises. And, with tightly the killed engine. That it did not occur, engineers at the beginning of the last century invented an oil filter. This small device undertakes all fire. The good oil filter, (at timely replacement) raises engine service life several times.
