12, really?

I just bought a 2000 Silverado 1500 with the 4.8l. Ran my first tank of gas through it and crunched the numbers to see that it only gets 12 miles to the gallon? 85% of my driving was expressway.

So any one have any ideas of what I can do to improve it? I would like to get it to 15mpg which shouldn't be asking to much I think.

Thanks,
Josh
