thanks very much for the info

I see what you mean about the engine load vs revs.

Would i be better to concentrate on coasting in neutral with the lump at idle? I have several points on the commute that could allow me to coast for 2-4 tenths of a mile at idle in neutral.

Is that more efficient than coasting down with the car in gear?
