Can I save fuel by changing the oxygen sensor?

The fuel can be saved by replacing the oxygen sensor, but the specific amount is affected by the vehicle condition and driving habits. For the oxygen sensor, it mainly detects the oxygen content in the exhaust, and ecu corrects the fuel injection quantity according to the data it sends out. The following information is about the failure of the oxygen sensor:

The following information is about the failure of the oxygen sensor:
1. Oxygen sensor poisoning: It sounds strange, but it is one of the most common oxygen sensors and difficult to deal with. It usually happens in the car with leaded gasoline, so the service life of the car's oxygen sensor is only a few thousand kilometers. In minor cases, it can be solved by changing a box of unleaded gasoline, but in most cases, it will invade its interior and eventually lead to the replacement of parts. To sum up, the service life of oxygen sensor can be improved by using high-quality fuel and lubricating oil, selecting and installing rubber gasket correctly during repair.
2. Carbon deposits are formed on the surface of the oxygen sensor or sediments enter the oxygen sensor inside: this will prevent or block the external air from entering the oxygen sensor, making the output signal of the oxygen sensor inaccurate. In this case, it is necessary to remove the carbon deposits and sediments entering the inside. Of course, when the car's fuel consumption increases, you can also check the spark plugs, batteries, etc. to see if they have problems.
