Not maybe.

Engine-on coasting is what got me above 47mpg (or below 5L/100km) .
I was using DFCO and braking as little as possible before I started coasting, so the combination of both is inferior to engine-on coasting.

My engine uses 0.5L/H while idling.
So it takes 10H to use up 5L.
As long as I do 100km in those 10H of idling, or 10 km/h, I'm still only using 5L/100km and getting 47mpg.
As long as I'm coasting faster than 10 km/h (6 mph), I'm doing (far) better than 47mpg even with the engine on.
