No low fuel light. Must be an EX thing. <sigh>
Poor mileage like m735is said, a lot of it depends on driving style, health of the engine, terrain, and I've found...quality of gas. Do the basic things like giving your engine a tune up. If for nothing else, baselining when those things get replaced so you'll know for next time when they need replacing again. I bought my 95 with 130K miles on it and changed out the following: plugs, wires, cap, rotor, air filter, fuel filter, oil+filter, brake fluid, and antifreeze. I also bought the engine cleaning stuff from Auto Zone and cleaned the heck out of my engine. This way I can tell if I develop an oil leak or not.
I literally lose about 7 to 10 miles per gallon if I use generic gas in my car. I average 38MPG. On my worst tank (7-11/Citgo gas), I got 28. If I stick to 87 octane name-brand gas, I do better.
