The reason I ask is while I was traveling to Georgia I filled up and the pump said I took 33 gallons. I really figured I'd gotten screwed by a inaccurate pump meter, so since then I've let the fuel light come on a time or two just to see. I've used several different pumps around town and have put in between 28.7 to 30.5 gallons. That's letting the foam die down and topping off several times.

So, is every gas station cheating me or does a 28 gallon tank actually hold over 28 gallons because of the filler neck, etc. If so, what's the actual capacity?
