Will disconnecting the oxygen sensors improve your gas mileage?

God no. It'll make it worse! Oxygen sensors are what constantly tell your ECU the air fuel ratio. If you disconnect the sensors it'll make your car run bad with a mixture being either too rich or too lean. That'll mess up your catalytic converter too which can be an extremely costly repair. LEAVE THEM PLUGGED IN!

Any proof of better gas mileage by wrapping the oxygen sensors in aluminum foil?
No, does not work.
Does not having o2 sensors in your tires affect gas mileage even if the tire is inflated properly?
Tires do not have oxygen sensors. They can have pressure sensors. The lack of pressure sensors would have no affect on fuel economy.
Can you bypass oxygen sensors in a Ford Freestar?

What happens running a Toyota sequioa with bad oxygen sensors?
Very bad gas mileage. And can prematurely plug your catylitic converters.
Can removing emissions equipment improve gas mileage?
If you removed ALL emissions equipment, the question would be hard to answer, in theory anyway. Removing individual equipment such as your Catalytic Converter would improve exahaust flow and improve gas mileage. Removing your Oxygen Sensor would most likely decrease gas mileage because the Oxygen Sensor helps control the air/fuel mixture.
2001 Toyota Camry giving 24 miles per gallon. why is it giving less mileage?
If this vehicle has high mileage I would start with the plug\wires and oxygen sensors. These would all affect fuel mileage on higher mileage vehicles. Hope this helps you.
What is the gas mileage for a 1992 Mercury Sable?
