Does Fuel Degrade Over Time?

I always assumed that fuel degrades over time, having a half life time of some kind. I have a 16 gal fuel cell i tend to top up ever time It drops 4-5 gallons, so I can check my mileage and keep weight over the rear wheels.

If I top up ever few weeks, there would be some percentage of fuel in the tank from months ago. Wondering how potent that gas still is, and if it could be hindering my numbers.
