I'm. Not really understanding how Range is calculated of maybe just updated. 120 miles into a tank I'm averaging 53.8 mpg with a total range of 512 whereas it's had the same expected range mostly through a tank before but around 49 mpg.
Your Fuelly average shows 47.7. Set your meter to show odometer, what does the average now show? Now set it to trip-A, now what does it show? I'm assuming you use trip-A for your tank mileage. Anyhow, the displayed range is just one possibility and is a guess.
Right, I use Trip A for each new tank. The car's computer mpg shows 49.2. I notice the range increase by about 10 miles after the highway portion of my 66 mi roundtrip commute and then it dips back down when I Eco/Normal mode off the highway. With a range that's seemingly dynamic I was wondering why, at 53+ mpg for Trip A, the range isn't inherently increased in the range.
I believe the range can also be impacted by the use of the climate control (just turning it on will probably drop the range) as well as the outside temperature (for example, you may notice that the range is estimate a little lower on a colder day).
I believe the range takes into account the mpg on the last tankful as well as current mpg, that's how it works out what figure to display when you first fill up.
