Not long ago, I had to finally refill my new Outlander PHEV after purchase in May. I was able to get 159 MPG, by being diligent to use EV only mode as often as possible. Most my driving is a daily commute that is below the 25 miles all EV range. On my second tank, I'm only allowing the car to use default mode (hybrid) with no active selecting of EV only. I'll report back, but so far, very pleased.
