all that downshifting to stops is just beating up the synchro's

The efficiency of this engine is very sensitive to environmental and situational conditions. My worst reported f/e is half my best. Predominately highway is 25% better than predominately city. Same for cold vs warm. I've never had a car which has such radical swings in economy. I can look at my logs and easily spot when it was cold, or predominately highway, or my wife was driving...

It could well be your change in road type utilization has hit you.

Yes, I've noticed some swings in fuel economy depending on how I drive it as well. I'm usually feathering the gas pedal and shifting before 2k rpm. I'll notice drops if I'm driving it half as spirited as I drive the miata. But I still envy the majority of people in this forum talking about effortlessly achieving 40+ mpg. On the same route from San Francisco to Los Angeles, we took a friend's civic VX and I was able to get 62mpg with my hypermiling techniques which was largely due to drafting behind large trucks most of the time and staying around 55mph as I did with the Yaris.

Hmm, first time I've heard that. I've just been trying to implement DFCO as stated in the pinned thread to squeeze every mpg out of the Yaris I can. I'm still on the original pads and rotors at 110k miles. (knock on wood)
