My 93 DX 4dr can squeeze 300 miles out of a 10 gallon tank with a bad cylinder head. I will probably get more out of it when I replace the head here in a week or so. This is also assuming you keep your foot out of the radiator if you don't you can expect as little as 200 but still with gas cheap its a good car. I have heard of DX owners getting around 350 as well.
