Fuel Mileage Thread

Let's see some fuel mileage numbers and how they vary during the year when winter blends are used depending on where you live. So far,on the 2017 we have gone thru four fill ups and have averaged 26.1 mpg which is hand calculated and not taken from the car display. All fuel is regular and is on our winter blend. Driving is 70% city(suburban,not true city) and 30% highway.Should get better as I have been breaking it in running it thru the gears much more often than normal.

Below is a chart for the 2015 for the entire 2016 year with averages in red at the bottom of the page. Blue represent lows while reds are highs.

I wonder how much of a difference from the actual calculations and the computer display?

I use Fuelly.com to record every drop of gas that goes into my vehicles. 2015 2.4 Sonata over almost 2 years of 50/50 city/highway driving and we are at 25.5 mpg or 9.2 L/100km. Filled up yesterday after an all highway COLD winter trip and got 781 km/485 miles on the tank at 28.2 mpg /8.3 L/100km. Distance to empty at the time of fillup said 30 km and the low fuel light was on for 30 minutes of highway driving. Put in 65 liters and the tank holds 70. Not too bad considering winter tires and winter gas and cold temps plus a PACKED car with 4 people, dog and trunk loaded to the max.

The cars computer is one of the most accurate I have had, usually off by less than 10%. Here are a few stats from my Fuelly page.
