Fuel Mileage Related Discussions
I use the big red button on the dash - for long red lights, traffic jams, etc. There are several long lights in this area, and I time them so I know when to restart.
Does the car resume the same MPG session when you start and stop like that or does it start a new session every time you "pause" the car?

[QUOTE=Press Fit;1350002]Every start begins a new session, but, of course, the overall figure continues till I reset it.
Got 548.7KM (340.9 miles) on one full tank, with 3KM (1.9 miles) range to spare 
For this range, the Fuel Economy matched Honda Canada's advertised 6.1L/100KM for the entire trip.
Trip Details:
- Honda Fit EX-L Navi CVT 2016
- ECO Mode OFF
- 1 Driver, 1 Passenger (280lbs total)
- 80lbs cargo
- 90% highway, 8% stop-go traffic and urban, 2% "S" Mode passing
- 27°C to 32°C (80.6F to 89.6F) outside temp
- Auto Climate control set to 20°C (68F)

If so, I have no idea why they would fluctuate like that. The bars should go to the left as gas is being used.
The "bars" below the temperature are the equivalent of an analog gauge and are at best a WAG (Wild Ass Guess). The range numbers are like the bars (digital) but are a little more accurate therefore are SWAGs (Scientific Wild Ass Guesses). Both are pessimistic. When the little orange gas can icon lights up, you've got a WAG of about 60 miles. Look for fuel between now and then.
Indicators depend of the temperature and attitude (up or down hill), length of last trip, etc. As said above the various indicators are guesses and tend to get you to get fuel before being stranded on a lonely stretch of road or a really bad neighborhood.

The biggest variation in mileage is between a cold engine and one that is warmed up. Huge variation. Make a lot of short trips on a cold engine, and you will lucky to average 30 MPG.
Did a 275 mile (each way) round trip over slightly rolling terrain (across Wisconsin) in our 2016 LX CVT with 2700 miles. Filled up with gas and immediately hit open road. Used Eco mode and had AC on for about half the trip each way. Cruise control most of the way.
Outward trip: Upon arriving at destination the car reported 54 mpg. Never exceeded 65 mph. No noticeable wind.
Return trip: For the final 200 miles the car reports 48 mpg. Did 70 mph where I was doing 65 mph outward. On the westward return trip there was a fairly strong wind blowing from the SW so that may account for part of the drop in mpg.
I don't have a clean set of numbers for fill ups but we filled up, did the outward journey, arrived (I noted the reported 54 mpg number), drove around locally for about 40 miles, then did part of the return journey before filling up again (3 marks on the gauge), reset trip meter. 375 miles, 7.294 gallons. At this stage the car reported 51.8 mpg and calculated mpg from fill-up data is 51.4 mpg. So given that part of that 51 mpg includes a quarter of the miles done at lower mpg it seems the 54 mpg reported at the end of the outward journey is real!
The car did most of its trip at 2000 rpm. I think I saw it go up to 2500 rpm once when going up a hill.
Maybe this is mentioned elsewhere but how does the car determine trip mpg? Is it through metering fuel injection or is it saying you started with a full tank and now have half a tank which is X gallons used and you have done Y miles and determining from that?

Living in New England the highways are a lot of ups and downs, so it takes a little bite out of the mpg. I'm averaging about 37 with all of my crappy suburb driving, but on a trip to Long Island recently I averaged ~41mpg there and back
