Thank you very much for the follow-up.

I'll do the fill-up procedure when I need gas next, probably late next week. I'm curious how much more accurate it will be... I've noted my averages mutiple times between two homes (getting our old home ready for the mkt), so I'll see what the difference is when more accurate.

I must admit that I'm pleasanty surprised so far, assuming the readings are somewhat accurate. Local driving I'm seeing about 36 to 37 mpg. When I've had some highway mixed in, about 40. Actually today, when I got off the freeway, while at a light idling, I saw the average go from nearly 41 to almost 40 (2 minute wait). Damn. I had no idea idling was that detrimental...

Again, really curious to see if these numbers are true, as compared post fill-up procedure. I have the car's weight down to about 2,290 pounds (1/4 tank of gas). That excludes me, but I'm only about 140 pounds...

Thanks again.
