Our 1988 Mercury Cougar with the 3.8 liter V-6 dropped drastically in mileage to an average of 10.5 mpg. I checked one of the oxygen sensors, located in the exhaust manifold, and it was filthy so I cleaned it with carburetor cleaner. Our mileage shot up to 18 mpg and the car is running better. I haven't gotten to the other oxygen sensor because it is in a difficult to reach place. I will be replacing both of them in the near future.

Why does fuel consumption increase when the speed of a car increases?

A car needs fuel to run. So when a car increases speed, its need for fuel increases too. The faster the car is going, the greater the need for fuel to burn will be. The same is true of when a car decreases speed. When a car decreases its speed, it does not have to burn as much fuel. ------- The wind resistance against a car varies with the cube of its velocity. This means that the amount of power needed to overcome the wind resistance is 8 times as much when the speed is 2 times as much. At 50 or 55 miles per hour, most cars are putting over half the fuel they consume into overcome atmospheric resistance, where at 25 miles per hour it would be less than ten percent. This in turn means that the number of miles per gallon of gas is reduced by quite a lot as the car goes faster.
