But my question to anyone who gets 50 + mpg is
.how fast do you drive on the freeway and get that mileage?

Thanks Wayne,
I'll try to drive @60 miles per hour for 300 miles or so
and see what the mileage is,
o by the way I dont look at any of the mileage indicators or average readouts,
while I drive I just do the math at the fillups.

On my commute to work there are a lot of small hills, which I continue to go up and down for most of the drive. The fastest posted speed limit on my commute is 65 miles per hour not many people stay at that speed. Only a few miles are 65 where the rest is 55 MPH. I have found that maintaining a speed between 62-65 yields the best FE. Soon as I go over 65 unless drafting or going downhill or on flat ground my FE drops. The other day on flat ground and drafting behind a truck I was able to maintain EV mode for about a mile at 77MPH. Even when EV mode stoped I was able to maintain speed and Maxed out FE for a little longer. The road began to change altitude slightly and the truck started pulling away from me. My FE then droped and I then slowed down and regained FE. As a rule of thumb maintaining 62-65 I recieve about 75 MPG when the instant FE display is half way in between 50 and 100 MPG. Even better FE can be acheived at 53-55 MPG, if you can maintain that speed on the highway. Also, recently I stoped using Cruise control which has increase my mileage on the drive to work due to the hills. This tank should be my best yet with between 53-55 Mpg with about 100 miles to go to finish out the tank. On flat ground the cruise is great and does not effect FE.

Jerry, I wasn't going near 70. I don't think I have went up to that speed in my car yet and if I did it was once or twice. I sometime pulse up to 65, depending on whether or not traffic will pass me or not, otherwise I would only go up to 55, sometimes 60. I didn't try to go any faster mainly because it was cold and I was having a hard time maintaining even 60 mpg without continuously losing speed. I even thought I could feel the lean burn kicking in and out (unless that was something I need to have checked under warranty). I had a bad FE day, a lot of hills, bad traffic (bad drivers - pulling in front of me and turning, etc.) so I only manage low 50s, very disappointed. At least there isn't too many miles yet so I can pull it back up. I need to move to a more rural area

I will try some higher speed driving once the temp stays higher. I think tomorrow should be good if I can get the free time and will report back
