The fuel additive container should say "O2 sensor safe".
Tires do not have oxygen sensors. They can have pressure sensors. The lack of pressure sensors would have no affect on fuel economy.
The oxygen sensors control the amount fuel in the engine and if it is making too many emissions the oxygen sensors will cut back on the fuel or if they are worn out they will increase the amount of fuel. The catalytic converter will eventually get plugged up if the Oxygen sensors are bad. The oxygen sensors control the converter.
Upstream oxygen sensors send a signal to the PCM which adjusts the fuel mixture ( air / fuel ratio )
All of the engine sensors can affect fuel mileage.
fandango additives usually which contain oxygen
IT SURE WILL. It must have them to run right. With out the 02 sensors it will use alot of fuel.
air fuel ratio sensors are in the exhaust-they are like oxygen sensors but work differently
A fuel level sensor will not affect performance. Fuel level can due to weight of fuel and accumulated heat in the returned fuel from the engine.
It shouldn't, but if your injectors were dirty, then the O2 sensors probably are too.
There are a total of ( 4 oxygen sensors ) according to the engine wiring schematic for the 1997 Mercury Mountaineer in my Haynes repair manual ( 2 oxygen sensors are " upstream " sensors used by the PCM to adjust the air / fuel ratio of the engine ) ( 2 oxygen sensors are " downstream " sensors / catalyst monitors )
There are 3 oxygen sensors on this vehicle. Some of the Highlanders with California emissions have 2 fron Air/Fuel Ratio sensors and one rear Oxygen sensor.
two oxygen sensors for air / fuel ratio (and another two oxygen sensors that are called catalyst monitors installed downstream )
