How long until it runs out of gas

Once you see the low fuel light.

I realize it depends entirely on driving style and condition of the engine/things that affect mileage but I'm just curious how long one might have left once the dreaded light comes on.

Ive never put it to the test. Has anyone?

Rest In Peace Mom.

My gauge sticks slightly at the 1/4 mark and whenever I push it past that it stays at one 1/4 for days and days. Then abruptly after a hard bump or turn it will peg below E and the light comes on. Anytime that light has come on I pull over immediately I've only put 2 miles on the car at a time with the gas light on. I consider that as my cars way of saying gas now or get out and walk *****. I'm curious to know though.

I have. I have driven 12-15 miles with the check guages light on....I never have run it out of gas.

Ever since my SC speedo install, my fuel guage likes to slowly drop to E when I turn the key off, and then slowly rise to wherever the fuel level is once I turn the key back on.

Ever since I got a new fuel pump, my check guages light will come on, guage way beyond E, and I can never pump more than 14 gallons into my previously 18 gallon tank. All I can think of is that my fuel guage is faulty.

I've always wanted to get it low on gas, with a 5 gallon gas can in the trunk see how far it will go before it dies. Of course, the weight of that full gas can in the trunk will effect the milage some

I've done about 30 miles of local driving with the check gauges light on and have never had an issue.

When my check gauges light comes on I have 2 gallons left in the tank. Once it came on right as I was pulling in to get gas and it took 16 gallons even.

My check gauges light doesnt come on for my fuel because I had a VMM...

I normally drive 30-40 miles in my Mustang with the Low Fuel light on...

Well my needle seemed to almost be on E, I managed to get a 4k round trip on it, but when i parked and started it again I had just under 1/4 tank.


Sometimes i don't like the slosh module. I wonder if there is some way to mKe it update a bit faster.

Rest In Peace Mom.

Actually, yes, you do have a "CHECK GAUGES" light and it will come on - you've just not run it down that far yet!

On my 19G gas tank, the "Low Fuel" light comes on about 14 gallons down, the "Check Gauges" at about 17.5 gallons down.

No, I'm not proud of knowing that

IMHO it is not a good idea to let any fuel tank get less than 1/2 for a couple of reasons:

1. If the pump is in the tank, the submersion in fuel helps keep it cool.
2. If gas is not available (due to, oh I don't know, maybe a bunch of tornados rolling through taking out the power infrastructure), you still have a way to be mobile for at least a little while.

But just my .02.

Whereas I agree with you (well, to the 1/4 tank mark for #1), I quite often have to drive 300 to 500 miles in a day, and gas prices in parts of Texas and Arkansas are easily 25 cents higher than others ... plus, I try to run no-ethanol, and THOSE are a bit harder to find

Actually, from experience I've found #2 is a better reason than # 1. That is - for us.

There's all sorts of variables but having good reason to believe my bird #2 got 300 Kmiles on the original, or at least 160 K on a replacement, dont be anal about that fuel pump cooling deal with your nineties fords. I always drive hi-mileage cars and I've replaced like 2 fuel pumps out of over 10 cars. One of those on the bird I just got.

I learn more about cars every day!

I hear you, Pettyfog.

However, my 2000 Malibu was "Fuel pump a year" while my wife was driving it, running it almost empty every time (13 gallon gas tank, typical fillup was 12+ gallons (!!!) )

Now that I drive it and do my darndest to keep it over 1/4 tank, I've not had to replace one in three years now.

(Also used an ACDelco last time, instead of the Airtex that the local mechanics were using ... )

Some truths are held SELF EVIDENT and span the knowledge of car fan groups!!!

Having seen that 25 % of blazer driveabilty probs are FP related, EVEN though their FP sit in a sump of fuel.. that 'conventional wisdom' applies EXACTLY to GM owners!
- also that Airtex SUX. If you have a GM, AC DELCO ONLY! {Who knows what Delphi might buy at any given moment}

Really? I think my gauge goes down to E way earlier than it should and it scares me...

I don't ever have a problem, just keep it above a quarter tank. Or you'll regret it later.

It is "interesting" for Chinese values thereof, that's for sure.

As a data point, I had pumped out all I dared to from my tank before I started working on the replacement fuel lines.

I drove it to the nearby Shell (about 1 mile away) with 1.5 gallons in the front seat in a gas can.

I then put 19.777 gallons (!!!) in my 19 gallon tank.

So ...

Heh. All it takes is money

Oh, and a parts yard that DOESN'T cut the gas tank before putting it out in the yard.

There's two yards in Texarkana that I could get the tank from, but they charge more (and are 70+ miles away.)

Thankfully I don't need a gas tank (Arizona/Utah car), DD has more rust on his old brake line brackets than I have on my whole car and Dan just replaced my FP in May.. I am thinking about doing the back dual exhaust though. I need to put my SC rear bumper on and it would look funny with one muffler.

Along these lines, do we have a reserve tank in the later models? One poster said that they filled up to 18.7 gallons. If you have an earlier model tank (my 89 is 18.8 gallons) I could see that happening, but do say '96 and '97 have a reserve tank?

i read somewhere that when the low fuel light comes on its saying theres roughly 2 gallons of gas left in the tank. i myself dont like it going below 1/4 (my work is a 55mile round trip each day) but sometimes you do what you gotta do.

97 green, 4.6L sport package. k&n cold air from an 01gt. so far my best at the strip was 15.808 @ 89mph at new england dragway.

Well when I filled it, it took 12 gallons so there was a bit left I guess. However finances often prevent me from being able to keep it full.

The worse part is the recurring pattern of gas being down in price and then the day we get money it's gone up... A lot.

Rest In Peace Mom.

Suggestion?

When you have some extra money, buy a prepaid Visa/MasterCard.

That way you have some to fill up with.

(I'm putting $250/week on a prepaid card to do fillups with. I also shop a lot at Kroger locally - the local Shells give 10c off if you have over $100 in points on the Kroger card. Helps offset when I can't get ethanol-free gas for whatever reason, especially since Ruby Jean, the Cougar, really wants midgrade gasoline.)
