I finally got a OBD and connected it via Bluetooth to my Tablet. driving my regular commute today was a new experience. I always assumed that a car driving at 2000rpm was burning the same amount of fuel whenever it was at 2000 rpm. now I see that rpm has nothing to do with fuel consumption. Iwas amazed at Tbe jump in fuel consumption when climbing hills, and disappointed b y how little a difference coasting downhill or driving downhill actually make.

I am wondering now if I should be accelerating down hills and coasting as much as possible uphill.

my commute is constant ascent and descent one after another with very little flat ground.
