How much gas is left when the fuel light comes on?

Just bought a 2001 Grand Am GT. I'm trying to figure out the typical gas mileage I'd get driving 65mph on a flat highway. I drive 100 miles a day so I'm just going to fill it up and drive till the light comes on.

When the fuel light does come on about how many gallons does the tank have left, or how many miles can I get before the engine runs out. Obviously I don't plan on doing this (running it down past when the light comes on) often as it'll put a lot of stress on the almost 10 year old fuel

I figure if I can get about 340 or so miles that'd be good since the tank is only 14.2 gallons from what I've read. That'd be about 24mpg give or take.

Check the owners manual for the amount of fuel left when the light comes on. Usually 1 to 1.5 gallons but not much more. I wouldn't press it beyond about 20 miles if the light comes on as you may find yourself stranded along the road.

Usually my car takes right at 12 gallons when the light comes on. I fill up until auto shutoff kicks in.

My s-10 has a 4gal reserve. I can go about 80miles before it runs out. I believe I do have a bigger tank then most though. 18gal tank on mine. Only one way to find out though, just toss a gas can in the trunk and go find out:smile::tongue:
