When you use engine drag (car in gear) you are turning all fuel to the injectors off=DFCO=Decelerate Fuel Cut OFF.

RIDE, thanks, I like your explanation!
However, for the CRV, it seems there is no DFCO, unless the Scangauge is wrong. Downhill in "D", I see 0.8GPH used, and up if the grade is steeper and the engine RPMs go up. Shifting to "2" or "1" increases consumption too (slower speed higher RPMs, duh! and no DFCO?).
What Del Sol model year were you driving? I have a '93 Si (D16z6 1.6L SOHC VTEC engine), there is also the S (1.5L non VTEC) and VTEC (160HP 1.6L DOHC VTEC). The S has the best fuel economy...
