Of course, the Dart (which is now back to being mainly @Seanette’s car, now that I have my Jeep* back), can run on E85. It gets about 80% of the miles per gallon on E85 that it does on straight gasoline, but most times, E85 is enough cheaper than gasoline that it comes out costing less to run the Dart on E85.
* The Jeep broke down almost three months ago†. Initial attempts to get it fixed went very badly, but eventually, a different dealership made all the difference, and now it is back, with a new Power Transfer Unit.
