i would think your right. there is no improvement. also think that P&G is only efficient /usefull in a large engine car. i tried it in a small engine 1L petrol and it used more fuel than normal. in small engine cars, motorway speeds require closer to wide open throttle anyway so there is no improvement.

motorway is different to city driving though and we can all benifit from not ideling the engine when DECELERATING. (EOC)
