Without knowing your driving style our replies would not be helpful. But on with the cruise set around 70 you should be able to go about 40 miles more after the light comes on. But I can avg 21 mpg on my 8 which is high.

The light comes on at about 13 -13.5 gallons burned. so figure your MPG times 2.5 or 3 depending on who you believe.

I have personally gone for about 55km (~35miles) with the fuel light on. Then I needed about 60lt to fill up
A couple friend of mine have even gone to about 60km (~40miles) with the fuel light on. But then you are risking a) your engine, b) a veeery long walk

I agree with Expo, I wouldn't run it much past 40 miles once the light comes on.

As I recall, the light is supposed to come on with about 2 gallons left but that is by no means absolutely accurate. I have filled up just after the light came on and mine takes about 13.5 gallons so that would seem closer to 3 gallons left in the tank. Of course that assumes you could run it completely dry without fuel starvation.

if you're going on some long trip today, put a jerry can in the back... 5 gallons will give you about 80-100 miles of extra range. And turn your 8 into a modern day pinto

I guess if everyone is just going to put up a number I'll say my safe number is 50 miles.

I personally did 37 miles after the light came on. My normal mpg is around 17-18. I was pretty nervous during my trip to the gas station. When I filled up, the station pump read 15 and some gallons, which seems odd if our tank is specified at 14.6 gallons (maybe reserve?)...

I'm one of "those people" who figures you ought to burn up all of the old gas before you put in new stuff. 50 miles is my magic number. But I have gotten caught far short of that. When the light comes on, start searching for your favorite petrol.

My manual says 15.9 gallons in the tank.

Thats because the tank is supposed to be 15.9 gallons.

Good Thread!
I was always wondering this. Seems like the fuel light comes on VERY fast after reaching 1/4 tank.

once i filled up as soon as the light came on and it was 13.3 gallons, which means that there was about 2.6 left in the tank.

40 miles seems about fair

the light comes on before the needle touches E. A bit conservative me thinks.

Reset mileage counter when low fuel light comes on. Run out of gas. Repeat three times. Add all mileage and divide by 3.

And the needles moves a considerable distance past the E line but once it hits that line in moves very quickly.

Either way the light comes on with around 2.5-3 gallons left in the tank.

i am not sure, so don't quote me on this, but i read somewhere that if you rarely go to E then the farther up the guage the needle is when the light comes on.

if you only run 1/4 a tank at a time (common when i was younger and you only could get a buck or two from buddies) then the light comes on closer to empty.

either way, i get about 15-19 mpg, when my light comes on i figure 10 miles till i'm going to be walking (that way im safe and not risking being stranded)

Ok this is the way me ole eyes see it .each 1/4 of the tank holds four(4) gallons.
the book says 15.9 and a 1/4 gallon in the tube on fill up.i think it's a 16 gallon tank and most get paranold when the light comes on as a safe measure from the factory(the good ole low miles per gallon fear)
seems to make sense to me as this keeps me from running out of gas.when the light comes on i head for a gas station in less then a 50 mile radius from where ever i am and no problems in four years so far!

I've never seen the low fuel light come on so what do I know...
I would say 20-25 miles of street driving just to be on the safe side.

Confirmed to absolute certainty (by my need to hoof it over to a gas station with a can in hand or a call to AAA) several times on my car:

CITY:
From full, 50 miles to the 3/4 mark.
Another 50 miles from 3/4 to 1/2.
Another 50 miles from 1/2 to 1/4.
Another 50 miles from 1/4 to "E".
4 miles and the light comes on after "E"
16 more miles and it stops cold.
HIGHWAY:
From full, 70 miles to the 3/4 mark.
Another 70 miles from 3/4 to 1/2.
Another 70 miles from 1/2 to 1/4.
Another 70 miles from 1/4 to "E".
6 miles and the light comes on after "E"
20 more miles and it stops cold.
YMMV...
