Default how many gallons can you drive after the fuel light comes on?

I know your supposed to have 2 gallons left.. but I have gone 75 miles... and then when I go to fill up my tank... say if I put 20 bucks in... it bairly goes past the line b4 the red zone...

So I am thinking there is a ton of gas left... anyway. I learned that its easier to fill up on half a tank... instead of e.. b/c when its on e you don't really know how much gas is left.

Hope this made sense lol

you have a 15.9 gallon tank so assuming your tank is divided into 1/6th as the has marks indicate then you would have approximately 2.65 gallons or whatever that number is left once the low fuel light comes on....HOWEVER, there is also a "2 gallon reserve" tank, as the owners manual states...so technically you have 4.65ish gallons left....

just going off what the owners manual says.

i've been a little over 80 mi so I have to agree that there is at least 4 gallons left when it come on.

It's really not a good idea to let the gas level get that low. You risk sediments at the bottom of the tank being picked up in the fuel line. Especially as cars get older.

The information I gain in this place never ceases to amaze me. It's like some type of online class for me-

That's interesting. I learn something new about these cars every day. Does anyone know any more about the reserve tank?

Good advice.....

It's also a bad idea with these high gas prices. Some of the "less used" fuels (read, PREMIUM) do not get their tanks refilled as often. This increases the chance of you getting sediment, or condensation in the form of water, in your tank.

I find myself filling up by the time I reach a quarter tank........I view it as cheap insurance.

The 2 gallon is included in the 16 gallon tank.
When the gauge level reach the red zone, the low fuel light comes up.
When the gauge level reach the bottom, you supposed have 2 gallon of "reserved" gas left, you actually burned 14 gallons of fuel from a full tank at this point.

But my experience is that the tank actually carries more than 16 gallons of gas. One time I drove beyond 16 gallons of gas according to my milage calculation, and I then was able to fill up more than 16 gallons (maybe 16.5 or almost 17 gallons if I remember correctly) of gas at the pump before the pump clicks. But I never ran out of gas, so I don't know the exact number.

I read there were four tips to increase gas mileage.


!. Look online the the cheapest gas in your octane range in your area.
2. Fi ll up first thing in the morning due to lower temperature in the tank
3. Do not fill up when the tanker truck is putting gas in the tank.
4. also fill up when the tank is half full

I read this in an article about saving up to 15 % on gas cost by doing this. The last three have to do with the gaseous (fumes) content in the flowing gallon. I don't know if any of this is true. What do you think?

I lost the website for gas pricing so if anyone has seen this let me know.

Got to watch those stations were you fill up (say 16.5 to 17 gallons). The station may not have totally accurate pumping units.
If you are putting in that much the pump might need calibrating.
Looks to be the station is cheating you out of some gas. [you by 16.5 gallons and only get 15. Station make out like a bandit.]
I'd stay away from this station, He gets richer and you get ripped off.

it's also bad for the fuel pump to let the tank run low all the time

I think the tank holds over the 15.9 gallons. I suspect that when an accurate gas pump clicks off, you're full. But you can jam another gallon or so in until it comes out the filler. Not the best idea, but on the rare occasion that I find cheap gas I fill as much as I can. I,too, have put almost 17 gallons into an almost empty tank, usually with 390-400 miles driven.

As far as filling when it is cooler, I think the theory is that liquid volume expands and contracts with temperature. So theoretically cold gas is more dense than warm gas. I doubt it makes much difference - certainly not 15%. You can test that by putting a gallon of cold gas in a sealed container, drawing a line a the top level, and leaving it in the hot sun. You won't have noticeably more gas after several hours of heating. But you will have a heck of a bomb.

I subscribe to the not letting the tank get to empty out of prudence. But a good fuel filter should remove any sediment that gets into your gas tank. I still try to fill up at around 1/2 tank because that's the old price point for a full tank, and $30 is not as painful as $60+.

OK, who's going to show everybody that they have big Brass ones and go out and run their car out of gas. Then just take a can of gasoline with ya with exactly one gallon of gas in it to get you back to the closest station where you fill it up to the brim. Don't forget to write down what your milage was when your low fuel light comes on too.
That way everybody will know once and for all just how reckless we all can be when we just don't want to stop at the "Robber" Gas station until we absolutely have to.

And as for using gasbuddy.com, I checked my zip code. There's a 10 cent per gallon range. 14 gallons, once a week times 10 cents is about $70/year and that's assuming that I always choose the most expensive gas station. Odds are it'd be closer to 5 cents a gallon - $40/year. My credit card gives me 2% back on all gas purchases - about 8 cents a gallon - $50/year, probably a greater savings in the long run.

The reserve refers to the 2 gallons left when the light comes on. There isn't another 2 gallon tank. 15.9 is all you get

Jusp pump 10 gallons and see if what you are charged equals 10 times the per gallon price on the pump states if you think a station us cheating customers

Well I'm not going to run my car out of gas but I can give you a very good estimate based on known parameters of my car, at 350 miles I put 14 gallons back in the tank, that comes out to 25 miles per gallon which is very consistent with my car, so using that it's easy to calculate, 15.9-14=1.9×25=47.5 miles till you run out after the light comes on. But we all know that that is not chiseled in stone because of driving conditions and Driver input. But based on that if you hit 397.5 MI you better be looking for a safe place to pull over, hopefully it's into a gas station, 😉

Traviss, you are responding to a thread that is over 9 years old, which may be a record! I recommend that you look at the posting date but in your defense, it's something we all must be aware of! LOL
