Is there a relationship between the fuel consumption of a car and the carbon deposit on the accelerator?

Hello, car waste oil has little to do with carbon deposition on the accelerator. In general, the fuel consumption is higher than the fuel injector and engine power of the three-way catalytic oxygen sensor. You got it? I hope the questions I answered will help you.
