Best thing to do is fill it all the way up, reset the trip odometer, drive to about half a tank, fill it back up and see how far you drove with the amount of gas that you used. You'll know how much gas you used by how much you have to fill it back up with.
Tanks are supposed to be 15.5 gallons. Mine is 11 gallons for some odd reason.

My stock L03 with the 5 speed NEVER got less than 19 MPG to a tank, and I didn't drive it easy either, it could get 28-31 MPG on the Hwy., 400-450 miles to a tank @ 75+ MPH

15.5 gallons? hmm, that's weird. i once ran out of gas in my '87 and a friend of mine brought a little gallon jug so i could make it to the gas station. when i got to the gas station i filled the beast up and it only took like 13.4 gallons... so i guess that means i got a 14 gallon tank!! wow, wish i had a bigger tank! haha
as far as gas milage goes, i'm only get like 10 mpg in the winter. that's b/c i use my car in the winter to do my route, and it's running most of the time w/ the heat on so my gas bill is nutz in the winter!! but i figured it out and i average about 16 mpg on a tank of gas... i'm only getting like 225 miles on a tank, and it's like 20 bucks to fill my tank! ahh! haha oh well, i love my Zs!

The automatic shutoff thing at the gas station usually clicks the pump off right at 12 gallons. I normally get about 18-22 MPG's and thats with a 350TPI and a 700R4. I was prett surprised the first time I calculated it cause my old car got about 13 MPG's with a 305.

I get usually 16-17mpg, usually a good combo of city and hwy.. i am not light on it either.. i got 21mph hwy.. i can pull off a nice 12mpg city too.
I always fill it up.. run it to about 1/4-1/2 tank and fill it back up.. reset the trip odometer every time.
