How to Change Your Own Oil Filter

Your car's engine depends on three filters: the oil filter, the air filter and the gasoline or fuel filter. These keep the engine's "lifebloods" of gas, air and oil clean. Dirty clogged oil filters will result in a bigger pressure drop across them, lowering the oil pressure in the engine. If the pressure loss is too great, oil filters are designed with a bypass value that opens and lets unfiltered oil through. Why? Because dirty oil is better than not enough oil. Loss of sufficient oil pressure can destroy the whole engine. The pressure drop across the oil filter goes up with engine RPM. At very high RPM, say around 4000 RPM, the bypass valve will normally be open due to the large pressure drop at this RPM. Dirtier filters have lower RPM thresholds for opening the bypass. Thus with a dirty filter, every time you rev up your engine you may be letting a shot of dirty oil through.

Dirtier oil is more viscous and the particles of debris in it may wear directly against the moving metal in the engine. This increases engine friction, which lowers fuel economy. So clean oil filters can help get better mileage. You can change your own oil filter and save some money. It is really easy. The video shows how. Watch and learn!
