My Ultra Gauge doesn't give any indication that the 1.6L in my Versa uses DFCO. I suspect you still have a pretty good margin of possible improvement. I've been driving my Versa since Feb. 2019. My worst tank to date is the first tank I ran through it at 42.345 MPG in cold/damp winter weather. Most of my driving is in the 40-45 MPH range on secondary country roads with c/c set. My overall average since purchase is currently at 50.1 MPG with my best ever tank about a month ago at 58.908 MPG. A little tip that I've found useful is when using c/c feather the gas on uphill runs to keep speed up and RPM's from going crazy because the speed dropped 1MPH below set speed. All my numbers are hand calculated. The dash readout has proven to regularly show about 4-8 MPG optimistic. On the tank that got 58.908 MPG my dash readout was showing over 65 MPG.
