Does anyone besides me drive the speed limit of slower to conserve gas?

I also do what you do. I commute to school on the weekdays 20min to get to my school. Cruise control helps save a lot of gas for me. Inflate your tires to proper psi and just take out some heavy things in your car that you don't need. Dont accelerate hard or brake hard. Changing your spark plugs or air filter so you can get more miles of that one gallon.
