How much is the cleaning and maintenance of the fuel system once (that is, cleaning the fuel injector and valve carbon deposit)?

First of all, cleaning the fuel system is not like lubricating system, which requires working hours, but how much depends on the car?

A Buick brand car of about 200,000 yuan, plus 200 yuan for materials, a bottle of cleaning nozzle, a bottle of cleaning accelerator and a bottle of gasoline additive (pour the fuel tank). The total cost is about 580 yuan, and the cost is about100000 yuan, so the cost is low. For Audi, it needs around 800 yuan. Generally speaking, it is used more with the power lion!

But the effect is not obvious without disassembly and washing. It is suggested to simply clean the throttle with carburetor cleaner, and the effect is good.

If you do it outside, you may only need 80- 100 yuan to remove it and wash the throttle.

But some brands need to match when disassembling the electronic throttle! For example, FAW Mazda, so I suggest going to 4S shop.
