Better to let the gas drop all the way close to empty or always have it filled full?

My co-worker was telling me to have the gas always me close to empty before refilling it and my other co-worker said she never let's her gas fall below the half mark.
I don't know myself but I'd think that it's better to let it be close to empty.

its best for your pump if it never ever runs dry.
that said, the 99+ fbodies have a kickass "fuel bucket" style pump system, that eliminates that problem unless you are OUT of gas.
for other cars, like my 91 for example, its best if you dont let it go at E... because the fuel does slosh around some, and the pump will suck some air.

You should never let your tank get even close to empty.
First off -- if you run out of gas you're looking at replacing your fuel pump. Go in the fuel forum here and see how many people have had to replace the pump after running out of gas. Also see how difficult it is and expensive to change a pump.
Secondly, it's the gas that keeps the fuel pump cool. It's not uncommon to have a pump fail after driving for hours with little fuel in the tank. A hot pump hit by cool gas has also caused failures.

Couldn't have said it better myself. I TRY not to run my tank much below an 1/8 in any of my cars.....and if you DO run low on gas(empty) it is a good idea to let the car sit for a while so that 15deg gas doesnt hit 150+ deg fuel pump

never let you gas run low. Many F-body (among other car owners too) have let their cars run close to empty before getting gas. Then once they fill up at the gas station and try to start their car, NOTHING HAPPENS.
They burnt out the fuel pump. Your fuel keeps the pump cool!

everyone has their own theory on this, pretty interesting stuff to read.
I like to wait til the check gauges light comes on then ill look for gas because i dont like old fuel that has been vented and might have lost some of its characteristics etc to "dilute" my new fresh fuel.

I'm surprised no one has mentioned weight and fuel economy. Full tank = more weight, less fuel economy decreased performance. I would think 1/10-1/2 tank at the most. Don't let it go empty but don't rush out and fill up all the time either. I'm sure someone smarter than me or someone with morre time or both can figure out the math. How much gas in a tank (gallons) how much does a gallon of gas weigh etc...

put like 30,000 miles on mine since i've had it and have never put less than 15 gallons in it when i fill up, so with an average of 300 mpg thats like 100 fill ups with no problems...but i might have to change my ways if the fuel pump takes a beating

The less fuel you have in your tank, the more air you have, and when the temperature changes, the more moisture will condense into your gas tank. That alone is reason enough to keep it on the high side of empty. Power outages, and other unexpected events, phone calls in the middle of the night. Do you really want to have just a little bit of gas in the tank?

I let it hit the "check gauges" mark before i fill up, and seems like its gonna be empty, but when i fill up, it only fills like 13.5 g at the most!, so theres still 3 gallons in that sucker. the most I have ever filled up was like 14.5 gallons, and i for sure thought I was going to run out of gas in minutes....
