I use premium 91 RON unleaded petrol and mostly fill it with 60 liters. I just checked that the car consumes 16.3 liters / 100 KM and the average speed is 35 KM/h. This is the first time I make calculations and I will start tracking the distances, so I made an estimate by dividing 72 liters by 16.3 and it gave me 442 KM to E. Now I'm starting to doubt myself and feel a bit dumb even though I'm sure the fuel gauge runs down slower when the DTE is high and I spend more days without refueling in a somehow routine driving every week that is mostly on open roads. But if DTE is based on these calculations I don't think I witnessed it increase when conditions are better. More calculations are needed then and perhaps another check in the winter is a must since the car drives better back then and in our extremely hot weather I use the A/C in auto to produce maximum flow. I don't drive the 2011 Expedition alot so I don't know the numbers but I will calculate for it too since in my own beliefs it doesn't have the same issue. My friend has a 2014 Edge Limited, his home is much further than mine to the university, and said that his DTE is above 500. It might not be relevant since each car his a different engine but I want to compare and be sure. Also I don't know where I can get a scanner to pull codes around here.
I don't know if this should be in another post but it might be related. A smell of burning gas builds up by time and I smell it even if I only push the pedal a bit harder like halfway through. This issue has been there for a long time, maybe ever since I noticed the DTE, and It goes after each check-up when the clean the engine but they haven't told me anything about it even after requesting. Also I'm afraid that unplugging the battery affected the transmission since recently changing to the 3rd and 4th gear isn't smooth. Additionally, it got diffused twice on me recently when I started the car and put the shifter on D with the pedal having no use and the car revving. A simple restart fixed it.
Thank you so much for getting me less worried and giving me information that no representative gave. You have all my respect and I would like to say that this website must be seen by every Edge owner.
