three main things I've noticed will drag the Yaris mpg down :
1) Hotdogging. Enjoy it, but you will pay in reduced mpg. You knew it, come on.
2) Cold temperatures drag the mpg down during the cold engine (rich mix) time, drops mpg 1 to 1.5 less.
3) Using the AC drops mpg 1 to 1.5 less. It really is a little engine...

4) Drive Thru Fast Food. Talk about a gas waster. Imagine a line of Hummers waiting for their Big Macs!
