For my Kia Rio {1.6L / 5 Speed}, engine braking increases my consumption. I try to anticipate lights and traffic snarls, coasting out of gear when possible until I can resume my normal rate of speed.
One of the biggest personal changes I made was slowing down. I almost never exceed the posted speed limit unless I'm coasting down a hill. Then, I'll allow it to go over a small amount. Speed, anticipating traffic and gentle acceleration made a real noticeable improvement in my FE and reduced my wifes stress level at the same time.
