P&G didn't work well on my original Insight engine. I could gain some average MPG when engine-off costing down hills, but for normal driving on flat roads the gains were virtually zero. My assumption is that with the tall gearing and low displacement, normal cruising was basically already near the perfect BSFC zone for the engine already. That engine didn't have turbo enrichment and timing retardation to deal with.
