How much is the car cleaning oil circuit?

By August 202 1, the price is about 300- 1000 yuan.

Generally speaking, the frequency of automobile oil cleaning is every 30,000-40,000 kilometers. The owner can increase or decrease according to your car environment, driving conditions, driving times and local oil products. If carbon deposition is easy to form, it needs to be increased or decreased appropriately.

Part of it is cleaned with a disassembly-free cleaning machine. This method is to connect the oil inlet pipe and oil return pipe of the engine with the oil inlet pipe and oil return pipe of the disassembly-free cleaning machine, and connect the oil inlet pipe and oil return pipe with a special interface to form a loop. This method is cheaper than "hanging bottles", and the price is around 400-500 yuan.

Matters needing attention in automobile cleaning oil circuit

After the fuel system works for a period of time, the carbon deposit and colloid formed by combustion will adhere to the fuel nozzle, making the fuel nozzle stick or even block. However, impurities and dust in air and gasoline can also cause blockage or blockage of the oil circuit, and eventually form carbon deposits and deposits on the injector (carbon deposits can also be formed in the valve, combustion chamber and intake pipe, but this paper only refers to carbon deposits on the injector).

If the oil circuit is not cleaned for a long time, carbon deposits and deposits will block the needle valve and valve hole of the injector, affecting the performance of precision parts of the injection system, resulting in poor fuel injection, poor atomization and even no fuel injection. It leads to unstable idle speed, rising fuel consumption, weak acceleration and difficult start.
