I have the extended range fuel tank, which is 16.9 US gallons. With a full tank, the range starts off at somewhere around 430 miles, which makes sense as, according to the car's trip computer, I have been getting 26 mpg mixed city/highway. The re-fuel indicator came on at about 350 miles and I filled up at about 380 miles. I expected to put in about 14.5 gallons, but it took 15.5 gallons to fill up the tank. That means that my actual MPG was 24.5, a drop of 1.5 gallons, which I consider to be materially different from that shown by the trip computer.
Has anybody noticed a similar difference? What could account for the actual MPG being so different from the trip computer's calculation?
Also, about how many gallons are left in the tank when the re-fuel indicator comes on?
Thanks.
