2 cents a gallon probably would not be worth it, unless one is partial to that particular station - we all probably have our own favorite gas stations.

 

Industry standard is that the light should come on with roughly 10% of the tank capacity remaining.

That would be fairly consistent to my experience. I generally can go about 30 miles after the light comes on. 10% of 300 miles to a tank = 30 miles.

 

25 gallon tank
I've gone 50 miles after fuel light and then filling up took 24.1 gallons. have done this a couple times.
so at about 16 miles to the gallon, I'd bet I could have gone to 60 miles after
the fuel light.

 

My 97 F-150 with the 4.6 has a 30 gallon tank and when the gas light comes on, which I try not to have happen, I have gone 65 miles. Not something I'm proud of though. The truck took 27 1/2 gallons when I filled up but you know as well as I do that a 30gl. tank won't actually take a full 30gl.
Now keep in mind that those were 65 hwy miles, and the last 35 miles were scary as hell. Hope this helps.

 

i can drive to the next town and gas is 9-11 cents cheaper... and thats only about a 9 mile trip to these gas stations

 

Let's say you got 13mpg on your trip to the across town.... That would equate to a cost of $1.79.(if fuel is $2.60 a gallon) If gas across town was $0.09 per gallon cheaper and you put 20 gallons in your truck, then you saved $1.80.

Net savings= 1 cent.

Even if you got 20 mpg, and you saved 20 cent a gallon you're still not talking but $2.83 in savings! And you wasted 20 minutes of your day. (assuming you went 60mph through town.)

I'm not getting down on you. It's a shame that the price is so high that people can show a small savings by driving 9 miles to get a better gas price.

 

My truck has 4 gal exactly when the light comes on.

 

Same here. 27 gal tank, light goes off, I fill up, and get about 23 gal. to go in.

 

25 gal tank. When the light comes on, it takes just over 21 to fill it. So about 4 gal capacity. Of that, I figure I can probably safely use 2 or 2.5 gals, or 30-40 miles.

 

I have run my guage well below the empty line( it appears) and once i put 27 gallons in my tank....I thought I had a 26 gallon tank, and that i just used some RESERVE...and got lucky....now from all you guys have posted i just rechecked the book and sure enough the long bed i have has a 30 gallon tank.. so i bet you may have OVER 4 gallons of gas when the light comes on.....because long after that light came on and I had daylight between the empty line and my needle....I put 27 gallons in my 30 gallon tank....good to know.....now i BETTER have that 30 gallon tank....because i have never run out of gas!!!!!!!!! I have a 4x4 super cab long bed. FX4...

the mere fact the truck is a long bed, makes for the 30 gallon tank!...correct?

oh by the way after new plugs , air filter and cleaning my fuel injectors and putting two containers of fuel injector cleaner in 2 tanks of gas...i still only get 14 MPG

got 103K on my 02............thats around town type driving.....

i think in the owners manual, it says i should ahve 4 gallons left.

 

I have a 27 gallon tank and by going off my gas mileage and trial runs , i have found that my fuel light goes on at 3 gallons, left, then 2, then 1. This is a rough estimate, but i am pretty sure it is right.

 

Umm, maybe it's me, 3 gallons left in a 30-gallon tank would be 10% left, which is the industry standard.

And yes, the long beds all have a 30-gallon tank.

I have a 94 so i have duel tanks. I noticed if i went to the line i only put in 13 or 14 gallons depending on which tank. So i just drove on one till it went empty and flipped to the other tank. They are supposed to be 18 and 19 in the manaul. Which is what i found to be true. I can drive for about 3 days on the line. In either tank i have about 4-5 gallons more after the needle hits the "E". I dont do that every time but its nice to know that if i ever do get in a pickle i can squeeze about 55-70 more miles out of it. depend on highway or city. yes that much. i was shocked as well.
