A Fuelly car needs three fuel-ups before it shows up public areas of the site. We've found that average fuel economy is all over the map when you only have a couple entries, but once a few fuel-ups have been added the average tends to even out to a more realistic number for the vehicle. Excluding newly created cars makes the list more useful for people who want to compare fuel economy.
If you want to see every single car on Fuelly click the "show all" link toward the top of the page and you'll see all cars regardless of the number of fuel-ups.
At some point recently there was a category added for the UK brand name of my car (Hyundai Coupe) as I can see 5 cars in that category when I browse all vehicles.
Previously I had to have my car registered on here under the USA brand name (Hyundai Tiburon). So I go to change it over and I cannot find an option for "Coupe" on the model list...?
I've currently selected "Other" and typed in the model manually but expectedly I have not appeared under the "Coupe" category and disappeared from the "Tiburon" category.
