I turned my heat off at every red light so the start stop would work and I was going the speed limit.  I would let off the gas and coast to red lights.  I usually average around 12.5 mpg.  I was surprised how much better it is when you drive like your 80.  I might do this part of the time going forward because TRX wheels are going on Saturday.  I will probably struggle to get 12 mpg on normal driving.
