So that's my question ... anyone know about how many miles i can get or how many gallons of gas is left when the fuel light comes on?

That's a good question.

I think it depends on the year and the size gas tank you have.

I have a 2002 with a 18 gallon tank. That's too small, so they made it bigger on later years.

I think that when it hits E, I still have 3 gallons left.

I agree with Steve -- there should be around 2.5 - 3 gallons left when the light comes on, based on my experience with other vehicles. So figure that you've got about 40 miles worst-case scenario when the light first comes on.

At the lowest level I ever let my Envoy get to the Driver Info Ctr computer showed a range of 59 miles, but I can't remember if the low fuel light was on or not. I think it was.

FYI - It's not a good idea to let the tank get below 1/4, and not only for the obvious reason of running out and being stranded. :lol: Below 1/4 tank the gas can slosh around enough that the fuel pickup tube is exposed (no longer covered in gas) which could cause stalling. Also, gas helps cool the fuel pump too, and more heat = shorter pump life.

haha ... yeah ... I know better than to let it run that low. I was just wanting to get a more accurate reading for gas mileage. Turns out I get more mpg out of my TBlazer with the I6 engine than my Wrangler with a 4 cyl. and 33in. tires.

I've been more than pleased with my TB's fuel economy.

For 275 HP to push a good sized SUV around and still get nearly 20 MPG highway. That's just plain fantastic.

Well i can tell you forsure is i own a 2000 silverado oneday i decided to go get a 5gallon gas can pump 10 bucks into it and when my gas light came on i was gonna drive till it ran completely out and shut off and i surprisingly got 67.2 miles out of my silverado 5.3L V8 and if ud like i have videos of the entire trip to confirm the fact that some will possibly get 67miles and that was no highway just back country roads and stop and go type of driving condition so i was quite astonished of the results.

Check this thread out.... another way to look at it, how many gallons left. After installing a completely new fuel system in my burb, i had 10 gallons left when the niddle hit the E, i never got a light on and im not even sure if i have one.

damn, 10 gallons left. I think something is wrong with the sender than, like its not set properly. it is a float on an arm, like can you bend it to read closer to 3 gallons?

I never even thought about seeing how far mine will go. I have a Sonoma with a 12 gallon tank and get 250-300 miles per tank in town. I have not gone out of town for a full tank so I don't know what it gets on the highway. sorry, I know I am in the trailblazer section, that 10 gallon comment made me comment

Hey, i filled the tank a brand new tank, i knew exactly how much fuel went in, ran it to empty and then filled it up again and did the math. you know how much work it is to drop the tank on a 97 burb? I dont see a problem but your not the only person to say something like that however the math adds up. i installed everything and yes the sender sat right above the bottom of the tank, a 42 gallon tank with a big flat bottom. I dont see a problem and in my books thats a good thing, especially since its become my wife's vehicle. I continue to monitor the fuel mileage and it keeps adding up. this truck gets amazing mileage at around 17 mpg.
