Hey all,

I was wondering if anyone knew how much gas is actually left in the tank when the low fuel light comes on, or about how far you can go before running out of gas. I know it can't be much because when I filled up yesterday when the light was on it took about 17 gallons.

I think there is about 1- 1 1/2 gallons left at that point. So if the light comes on you better start looking for a station.

I was able to travel 9 miles (city driving) before i was able to fill-up. But that travel was nerve wrecking! :eek:

Yeap, takes about 17 gallons (I filled her up yesterday :eek: ) right when the light goes on, so it's 1-1 1/2 gallons left.

For me (2005 LS)
there is 12 liters (3.17 gallons) left when the light come ON.

It is a good idea to fill up as soon as or even before the fuel warning light comes on. The fuel pump is in the gas tank and depends on fuel present to provide lubrication for its operation. Running real low or out of gas could cause premature failure of the fuel pump. Not to mention, a possible long walk....... :m2:

Agreed -- I try to never let mine get below a 1/4 tank under any circumstances. :m2:

I agree with Charlie on the practice of never going below a quarter-tank...Up north, where I live, I would be concerned about condensation build-up in the tank in the winter months....The other point made concerning the lubrication of the fuel pump definitely deserves some merit, also...The ONLY times that I let her go to the low fuel warning light level was to "maximize" my adding of one bottle of techron,which treats about 10-12 gallons of gas, which I added at approx. the one-half tank level, and lastly , to satisfy my curiosity at determining when that darn "low fuel" light would finally come on, which was around the 2 gallon mark from totally empty... :m2: :cool:

i had to almost perfect pumps in a row. It was 32.99 on my car then i filled my girlfriends tank and it was 23.99. Yeah i try to not let it go below a quarter either.

I was wondering the same thing when I got the truck, seems like the light pretty much tells you that your out of gas!! So I refer to it as the TOO LATE light....

there's over 3 gallons left and u can drive around 50 miles with the light on, depending on your drving habbit. Personally the only time i get gas is when the light is on. Yesterday i filled up for 40.00 bucks even, it was like 19 gallons flat.

19 gallons wow thats cutting it close.
I've read the posts that say that the fuel pump needs lube but I don't think its that big of a deal, I would run my '95 Blazer bone dry in college all the time; the fuel gauge would read 1/4 tank when it was empty. My fuel pump died at 175K miles.. I don't consider that premature... :m2:

My 2002 and my 2005 both would go about 40 miles after the light came on.

The fuel pump is in the tank and relies on the fuel around it to cool the pump. Running it dry will definitely shorten its life. Regarding JimmyJam's comment, lots have changed in vehicle design since 1995.

Better to get fuel in the tank than pay the price.

My low gas light came on today and I figured I should have at least 20 mi before running out. Well guess what? About six miles later the trailblazer ran out of gas!!! One neighbour had about 1/2 gal gas in a jug which was about 5 years old and was not enough to start my trailblazer. another neighbor had an empty 2 gal jug he said I could borrow to walk to get gas down the road 1/2 mile (how do these people mow their lawns??).

Another person was right, the low gas light is the "It's too late" light! DO NOT WAIT FOR THE LOW GAS LIGHT TO COME ON!!! IT'S TOO LATE!! Be sure to gas up your Trailblazer as soon as you drop below 1/4 tank. The tank holds 22 gal, 23 if you top off (your actually filling up the fill tube).

My 94 Ford Explorer had a pretty good cushion of reserve gas when the needle was on empty. My Chevy Trailblazer does not! Never ran out of gas with the Explorer in 10 years. Only owned the Trailblazer 1 year and both myself and wife have run out of gas! The low gas light is useless. Lures you into a state of false security but defeats the purpose it was intended for.

That's odd. I rarely ever let mine get down to where the low fuel light comes on, but the 3 or 4 times it has over the last 5 1/2 years, it always had at least 2 gallons left and sometimes closer to 3. Of course the EXT has the 25 gallon tank.
But any of the SWB vehicles I've rented over the years all had at least 2 gallons left when the low fuel light came on!

Keep in mind how flaky the gas level sensor is on these things, it doesn't help matters. I rely on my DIC fuel usage more than my guage.

If you have a 22 gallon tank and put 17 gallons in you should have about 5 gallons left and at 15 mpg you should be able to go 60 plus miles depend on your driving style, but be safe and fill up early.

I ran out of gas on two occasions recently. The first time within a mile of the low fuel lamp coming on. The second time the low fuel warning never came on.
