Air filters, oil filters and fuel filter is what we call the car "three filter", their role is filtered into any liquid and gas inside the car engine, the protective effects of engine, while it can also improve the efficiency of the engine, you can use the OBD Diagnostic Tool to detect engine efficiency. Now, it says the main air filter and oil filter replacement and maintenance points.
The main action of the air filter is used to filter impurities in the air, provide clean gas engine, in this process, impurities in the air are adsorbed on the surface of the air filter reach a certain mileage, it will form a black look, this time the filter effect has been very poor, and must be replaced in time, you need Launch X431 IV GX4 Master or Launch X431 Diagun III tools.

Therefore, the car must be kept clean air filter.
The internal combustion engine use, dust, metal wear, clean carbon and other mechanical impurities will continue to mix the oil, while the combustion air and exhaust gas oxidation of the oil on oil will also gradually produce gum. After using to a certain time, use Autel Maxidiag Elite MD701 or Autel MaxiDiag Elite MD802 tools to detect, machine filter surface will be attached to a lot of dirt, if from time to time to replace the oil filter there will be blockage consequences.
