Jonathan Lynch Posted March 12, 2016 Author Report Share Posted March 12, 2016 So low fuel warning FINALLY came on with 20 miles till empty. The fuel gauge turned a yellowish orange and "Low Fuel Warning" message appeared on left LCD screen. The remaining fuel gauge was a thin orange line, which did little to reassure me that I will be reminded about fuel. Guess I have to re-establish those 20th century skills of actually paying attention to my fuel level and when to fill up. I preferred my 2012 Sport which sent out a reminder when tank reached 1/4 tank level. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted March 13, 2016 Report Share Posted March 13, 2016 Wow, that's scary low! Quote Link to comment Share on other sites More sharing options...
Jonathan Lynch Posted March 25, 2016 Author Report Share Posted March 25, 2016 Next tank, low fuel warning finally came on with 8 miles to empty. Talk about scary low! Does anyone know if this might have something to do with being in my first 1000 miles? I think I recall something like this happening with my 2012 Edge Sport, too.

akirby Posted March 25, 2016 Report Share Posted March 25, 2016 Did you try resetting the mpg? It shouldn't matter but you never know. Quote Link to comment Share on other sites More sharing options...
Picturepro Posted March 25, 2016 Report Share Posted March 25, 2016 (edited) I went down to 67 miles to empty no light. 13.45 gallon to fill Edited March 26, 2016 by Picturepro Quote Link to comment Share on other sites More sharing options...
DougS Posted March 25, 2016 Report Share Posted March 25, 2016 My low fuel warning was on the other day, it said I had 32 miles to empty. I don't know at what point it came on, because my son was driving it before me. Quote Link to comment Share on other sites More sharing options...

DougS Posted March 27, 2016 Report Share Posted March 27, 2016 About 5,000 miles. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted March 28, 2016 Report Share Posted March 28, 2016 (edited) Believe I read somewhere that the low fuel lamp comes on based on your driving style. Inasmuch as the manual tells you that it's unreliable during the first thousand miles, would seem that it's developing a history to operate off of. (I'm making an assumption based on the information on page 179 of the owners manual). Edited April 2, 2016 by enigma-2 Quote Link to comment Share on other sites More sharing options...
akirby Posted March 28, 2016 Report Share Posted March 28, 2016 Pretty sure it uses either the last 500 or 1000 miles average mpg to calculate DTE. Quote Link to comment Share on other sites More sharing options...
Jonathan Lynch Posted April 1, 2016 Author Report Share Posted April 1, 2016 I'm only at about 450 miles. Will have to wait a while then. Quote Link to comment Share on other sites More sharing options...
Picturepro Posted April 2, 2016 Report Share Posted April 2, 2016 another tank down to 53 miles to empty and 14.7 to fill up Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted April 2, 2016 Report Share Posted April 2, 2016 another tank down to 53 miles to empty and 14.7 to fill up Believe when I let it run low, it pops up in that same neighborhood. I would guess that city driving, 40 or 50 miles would be more than enough. Highway 80 or 90 would be more appropriate. Quote Link to comment Share on other sites More sharing options...
omar302 Posted April 3, 2016 Report Share Posted April 3, 2016 Believe when I let it run low, it pops up in that same neighborhood. I would guess that city driving, 40 or 50 miles would be more than enough. Highway 80 or 90 would be more appropriate. Older generation (2007-2014) Edge/MKX had the low fuel light first come on at exactly 80 km to empty, then at 40km, then at 20km & finally at 0. (Not sure of miles since I use metric but probably 50, 25 & 12 miles). Also, whenever the car is restarted with less than 80km to empty the low fuel warning would come on. The same behavior was also in the 2008 Taurus I had & on a friend's 2013 Explorer. 1 Quote Link to comment Share on other sites More sharing options...
SweetCandyEdge Posted April 15, 2016 Report Share Posted April 15, 2016 The warning light on my 2016 Edge Sport finally came on at 36 km to empty. Quote Link to comment Share on other sites More sharing options...
Tronjo Posted November 8, 2016 Report Share Posted November 8, 2016 I had the same problem (or at least I thought it was a problem) and took the car to the dealer. The technician showed me an excerpt from the service manual (not the user one which is very vague) stating that the warning will come up when the fuel level in the tank is 1/16. It is plausible then, that the DTE value the warning will come up will be different each time because it will depend on the current average fuel consumption used by the system to calculate it.

akirby Posted November 8, 2016 Report Share Posted November 8, 2016 This is strange. My 2013 Fusion comes on randomly around 20-30 mte. Our 2016 MkX comes on exactly at 50 mte just like the older models. Quote Link to comment Share on other sites More sharing options...
Tronjo Posted November 8, 2016 Report Share Posted November 8, 2016 It is not only strange, it is also inconvenient. On my old Edge 2014 it was based on DTE and was coming up always at 60 km. Quote Link to comment Share on other sites More sharing options...
akirby Posted November 8, 2016 Report Share Posted November 8, 2016 I much prefer the 50 MTE warning personally. Quote Link to comment Share on other sites More sharing options...
Tjm623 Posted November 10, 2016 Report Share Posted November 10, 2016 Mine comes on when miles to empty gets to 35 miles. I've driven as low as 7 miles to empty and filled up. That was closer to comfort but i was on way home and gas station next to my house was closest one Quote Link to comment Share on other sites More sharing options...
akirby Posted November 10, 2016 Report Share Posted November 10, 2016 You still have at least 10% left at E which would be 1.6 gallons. Not that I would push it. Quote Link to comment Share on other sites More sharing options...
TheWizard Posted November 10, 2016 Report Share Posted November 10, 2016 I have seen this discussion on the Mustang forums as well and nobody has ever provided a satisfactory answer to the question "why would you want to run down to nearly empty?" I have a low fuel light that I have only seen once... and that was done deliberately just to see it work (the gauge turns red). Otherwise I always try to fill up with between a quarter and a half tank remaining. That's something that was drilled into me growing up in Canada and never changed even when I moved south. In snow country you don't want to get stuck somewhere without enough fuel to keep warm if necessary, and even here you don't want to risk getting stuck in a traffic jam for hours and running out of fuel. On a long interstate trip I tend to let it get a little lower to reduce stops (as long as I don't have my wife along) but with normal driving I see no reason to avoid a five minute stop to fill up. Can someone explain it to me? Quote Link to comment Share on other sites More sharing options...
akirby Posted November 10, 2016 Report Share Posted November 10, 2016 For me it's just laziness - I like to go as long as possible between fillups unless I expect I may have to make a long drive or get stuck in traffic. Luckily that almost never happens. But I usually get gas around 20-30 mte. I have gotten to single digits when we couldn't find a convenient gas station but that wasn't on purpose. My wife was also taught never to go below 1/4 tank and obviously that is safer. Quote Link to comment Share on other sites More sharing options...
Tjm623 Posted November 10, 2016 Report Share Posted November 10, 2016 I agree it is a laziness thing, coupled with how much you drive. When I didn't drive much it was no big deal to keep filling up at quarter or even half a tank as sometimes that was every 10 days or more. I drive 75 miles round trip every day for work, plus extra mileage after work or on the weekends. Sometimes I just don't feel like having to stop for gas every second or third day to "fill up". I run it down and go once a week. I live in cold weather and agree in winter months I'm less incline to let it go that long. Also with it being a newer car I don't mind as much. An older car I try to keep full as I had a fuel pump go from sucking a bunch of crap up in the filter. I'd like to think the first year or two on a brand new car there isn't enough in the tank to have that be an issue *fingers crossed* Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted November 11, 2016 Report Share Posted November 11, 2016 I ran mine down to 0 once, still have gas left. The count down is an average and even when it reads zero there's still gas left. Quote Link to comment Share on other sites More sharing options...
