In a diesel it's not going to give as spectacular a result as in a gasser.
If - like me - you don't want to shut down the engine during the glide, the net result is likely going to be marginal.
I've tried P&G (engine on), and while it looked good on the ScanGauge, the tank average nor actually refueling showed anything out of the ordinary.
I've found it to be rather annoying to other drivers as well - one's hardly ever alon on the road over here.
I've resorted to pulsing pretty hard, then coasting (engine on) to transition points along my usual route - turns, curves, stops, lights, anything requiring a substantial drop in speed.
I've experimented with the speed and place combination that I need in order to arrive at the next transition point with a suitable speed.
On longer stretches of road, I still use a constant speed.
