The vehicle will be running poorly or down on power for no apparent reason. The fuel will be contaminated from the internal rust building up over time since gasoline is acidic and eats away at the metal. The best way to tell is to physically remove the tank and inspect the internal surface for obvious rust and corrosion. This is very true of a vehicle has been sitting for long periods of time and especially if no additives were added to preserve the fuel. A quick way if the vehicle is carbureted is to remove the fuel line and attempt brief bumps of the starter to push some fuel thru the pump to drain into a clear container for inspection. Option two is to inspect the fuel filter if it is fuel injected.

How can you get bad gas out of your car?
Add 1 bottle of ordinary rubbing alcohol to the tank. If The Bad gas is just gas that has water in it, then the alcohol will allow the water to "burn" with the gas. == == The best way to do it is kind of a pain. Take the tank off and dump the bad gas out. While the tanks off would be a good time to flush it out too. You can use a ordinary garden hose and siphone the gas out of the tank.
How long does it take to get bad fuel out of lines?
Depends on how you get it out. If possible the tank should be drained and the lines disconected and flushed. If you can drain or syphon the tank on a modern fuel injected car the system should circulate the bad gas back to the tank in just a minute or two when trying to start the car. REMEMBER this will not work unless the tank has new good gas in it. The amount of bad gas in the lines should not hurt the new gas as long as you have a Half tank or more of new gas.
