How much does it cost to clean the carbon deposit, valve and oil circuit of Buick Sail?

Unlike the lubrication system, it takes time to clean the fuel system first, but how much does it cost to look after the car? A car with a brand of about 200,000 hours plus materials, a bottle of cleaning nozzle, a bottle of cleaning accelerator and a bottle of gasoline additive (poured into the fuel tank) is probably 580 yuan.

100000 or so, and the working hours are even lower. Audi, around 800. Generally speaking, power lions are used more! But the effect is not obvious without disassembly and washing. It is suggested to simply clean the throttle with carburetor cleaner. If the effect can be done outside, you may only need 80- 100 yuan to remove it and clean the throttle. But some brands need to match the electronic throttle! For example, FAW Mazda, so I suggest going to 4S shop.
