2015 Ford Focus SE 2.0L Flex Fuel Engine. 170 Miles Fill up? Cruise Issues!? HELP
 

I have a 2015 Ford Focus SE with a 4cyl 2.0L Flex Fuel Engine. When I do a full fill up it says 174 Miles until empty. I've cleared all of the Trip Info ect. I find it hard to believe a 4cyl Ford Focus would get 170 Miles till E. Do some city driving and highway driving and don't smash the gas. Anyone else had any kind of an issue like this? Also when I put on the Cruise control in the 70s sometime It will change randomly on it's own to Kilometers?

Are you using flex fuel?
I believe it gets less MPG and the vehicle can tell how much ethanol percentage it is and may adjust accordingly.
Does the gauge show the tank as completely full? It should get at least 250miles per tank at least I would say.
