I still think there should be a way for the user to set the various fuel types as they are different depending on your state/country. for example here in iowa we have e85 for ethanol. also there are different biodiesel blends depending again on region and homebrew.
also if you could look into the date format issue i'm having. I really prefer my date display (top bar) customized. I know other apps that had this issue in the past have found a way to fix.
maybe it would be easier/best to have a user.ini file or something where we can set our preferences.
great job btw, keep keeping on
