Using DFCO to increase your MPG

Reality check: Consider that if you manage to stay in DFCO mode for a full hour, you've only saved about 0.2 gallons of fuel (specifically due to DFCO) since the Yaris' engine uses about 0.2 gal/hr at idle. To get a 10% improvement in fuel economy over the course of a tank of gas, you would have to spend over 5.5 *hours* in DFCO mode. Do you think that you are managing that much?

You have quite the attitude about all of this, Steve. DFCO may have existed for a while but it is/was far from common knowledge. Just because you knew about it earlier doesn't turn the rest of us into bumbling idiots, or negate the uniqueness of me discovering and proving it on my own.

While what you say may be technically accurate you completely overlook the fact that fuel efficiency techniques bleed into and overlap each other. It is nigh impossible to extricate an intertwined technique from its siblings, so striving towards DFCO usage will invariably lead to more efficient usage of brakes and deceleration and downhill throttle control while simultaneously making the driver more FE-aware in general. If it is easier for folks to understand that whole set of skills simply as DFCO usage please let them be.

Please try to look beyond the trees so that you can see the forest. Getting caught up in the minutiae of an easy-to-understand and easy-to-use technique will do no one any good.
