There's three Justa's and an MCS on Fuelly now, unless your only counting known 6MT.

 

On the return trip, 300 miles between fill-ups, the on-board computer read 39.2 mpg. Calculating by the amount of fuel actually put in the tank, 38.7 mpg. Essentially the same driving conditons. I now have 900+ miles on the car. I am not sure there is really a break in period as far as gas mileage is concerned. I am very pleased with these results.

 

Thanks for the Fuelly page everyone! I'll register there too.

I'm also registered on fueleconomy.gov with both of our cars. Last time I checked there, I was the only 2014 justa.

I've only filled up the tank twice. So my gas mileage has been all over the place as a result. I spend most of my time reading the instant read mpg, it's my goal to make keep it about 30 whenever I can, whatever mode I'm in.

 

For those relatively new to Fuelly, I'd really recommend setting up your phone so that you can text your gas info for updates. Their iOS app (GasTracker) is dodgy at best, and I've had superb results just texting the gas fill-up information directly to Fuelly.com, and replies with updated stats.

Log in and go to the bottom of your Settings page to set up your mobile, here is a link to the SMS FAQ:

Thanks!
Quick question, how did you account for when you took delivery? I have no idea how much has they put in but I got with a full tank.

 

I got mine with a full tank as well. When you start a new car with fuelly, it starts at an effective "0" ... it will only begin to tally an average after the second full fill. Until then all the averages will show as N/A. So the fact that you and I got one with a full tank is moot.

A good practice is to ALWAYS fill the tank up. I remembered to make note of the mileage (about 8) on the car and subtracted it from the total odometer when I filled Toaster up for the first time. I haven't yet filled for the 2nd time so currently my stats say N/A.

If you're starting already having filled up several times, remember to set up Fuelly to enter your odometer reading, NOT miles from tank to tank. Entering your current odometer reading is easy, and the best way to not keep track of miles, and FUelly will do the math for you. You won't get an average to back when you first got the car, but you can start fresh and the more fuel ups you tally, the more accurate the average. Your dashboard will say how many miles you've tracked to date.

There is a "partial fill" as well as missed date option too, but I haven't had to use them.

I hope this helps.

 

Unless you find it easier to log trip miles like I have for years on Excel.

 

I don't think I have the fish as described on the first page... Is this with an entertainment option?

 

I believe you'll need one of the screen options (Media Package or Wired Package, or corresponding Connected/Connected XL options) to get the fish, if you have the stock radio system there's likely not enough room on the screen to display all of that, so they left it out.

 

Ok makes sense, thank you!
