How does different fuels change mileage?

I keep seeing ads from fuel stations that say their fuels increase the mileage of the car but isnt the car doing all the fuel adjustments?Wouldnt it still pull the same amount of fuel from the gas tank?

yea, its bullshit.

Base gasoline is set by the RON and Octane values, now some brands put cleaning agents, combustion assistants and stuff like that which can make your car run smoother and could cause a slight improvement in milage.

Premium fuel performance depends more on the compression of your engine, use the fuel specified in your car manual.
