I've naturally changed some habits since the CT. I don't go as fast as I used to, I don't accelerate as fast either, but the one thing I really incorporated is the "pulse and glide" or "accelerating and crusing" as they say in this text. This can really change the fuel economy.

Is this really true? I sure do hope not. I understand once you're driving a bit faster than the speed limit, your mileage will suffer, but really, 1 MPG per 1 MPH!?

For every mph over 50 mph, you lose approximately 1 mpg. Slowing down from 65 to 60 mph or from 75 to 70 mph will save you approximately 5 mpg.

From my own experience, this seems a bit too much.
I'll express in km/L,
If I go at 100km(about 60m) I do about 4.8l/100km(49mpg)
If I go at 115km(about 71.5m) I do about 5.4l/100km(43.5mpg)
So I'd say 2 for 1 based on my experience on the highway
