postmac,

Wow, what are you doing? Some of those numbers in your fuel log are great.
My numbers are great unless I hit traffic (wrong time of day), or get in a hurry on various road trips. I've also blocked my upper grille (gee, thanks Pontiac)...getting ready to cover the undercarriage space at the front of the car when it gets cooler.

As far as DFCO goes, I'm still using it as much as possible. Once the car warms up, it works from about 35-65mph. If I coast at those speeds, GPH drops to 0. Lowest engine load is 6 or 7 at about 57mph (a good speed at which to drive or coast, anyway). However, I think I'm going to return to doing Neutral (engine on) at lower speeds or to a stop. GPH maintains about .3 coasting to a stop or in neutral, but distance increases in N, obviously.
