I'm new to hybrids and I've read some posts re: how to maximize mileage. I've noticed that sometimes when I take my foot off the gas the MPG gauge falls all the way to Econ mode and sometimes it only drops to "60". My mileage seems to be pretty low around 33 mpg combined. What do I need to do to consistently get into this mode? I've been trying the pulse and glide metheod.

Any thoughts?
