well it isnt just rx7's thats said about. Most "older" cars have inaccurate gas gauges, that is to say, you could be higher than what ur gauge says, or lower. On top of that rx7's generally use a lot more gas than any other compact car. Its just a common knowledge kind of thing that if you go under a quarter tank you should be searching for a gas station.

Just try it out and see. Mine is almost dead on accurate. I can run it down the level with the E mark no problem. Or run it low and then tap on the tank and listen to about how full it still is. When mine is sitting on E it still sounds like it might have 1-1.5 gallons left

My car read a little under 1/4 tank yesterday and it ran completely dry, haha..of course you notice it when taking turns hard because your car will start "chugging"/hesitating until you start driving straight. I had like a mile left after I noticed it cutting out on an off ramp.

One of the main reasons isn't simply running out of gas, or starving the engine of gas briefly (say hello to deceleration. There's no gas in it then!!) But is actually to prevent sucking up a bunch of ****.
Most older vehicles by now have accumulated years of dirt/sludge/rust/crap/****/crap/junk and what-have-you. By running the tank nearly bone dry, you're makingthe concertration of **** that much higher. Thusly slowly clogging fuel pump socks, fuel filters and
--->injectors.
Now that's not to say your pump will fill with sediment after you run the tank dry, its just a consideration. Also, if you know for a fact your tank is fine (say you've had it lined recently) then you know that's not a factor.
Food for thought.
