Fuelly vs EPA estimated mileage error

[bestclimb]

Anyone else seeing Fuelly's EPA estimates being a bit off?

Fuelly says the EPA mileages for my car are
21 cty
27 highway
23 combined? average

from the EPA website it says
19 city
25 highway
21 combined

While the only thing it effects is my % it would be nice to see it corrected.

Where are you seeing the error, because the calculations for my car are accurate on Fuelly. The EPA site has one error for one tank because it uses odometer readings which do not include tenths of a mile on my car instead of miles per tank.
