MPG not caculated

[EODguy]

I drove 5301 miles on 7.705 gallons of gas when I entered this it did not calculate my MPG. No matter how I try to input or correct it there is not MPG entry for this fuel up. Is there a MAX limit to the MPG calculator?

It seems like simple math to me 5,301 / 7.705 = 688

Fuelly sets a limit of 299.9 mpg I believe. It does not cater for PHEVs.
