Lewis,
Thanks! I was pleased. I really didn't have to work that hard - long days of road time sure helps. Note that I have not exceeded 40 mpg on any other tank - trips, by far; not tanks.

I also was suprised to find that I was less obtrusive travelling at 65 in a 70 than at 70. At 70, I was close to the speed of others, including big trucks. At 65, people could smoothly pass me instead of me inching past someone else going slightly slower than I.

I did not always have the patience to go 65 - paticularly the last day looking forward to seeing my girls. Also made some good mpg progress in the 60 miles per hour sections going through larger towns; although could have, once again, done better because I sometimes drove 60 and sometimes 65 - should have driven 58 or so.

As far at your 42 mpg 150 mile run, my advantage over that was that I travelled 300 miles at a time, and then just a short stop (not enough to cool the engine), then another 250 to 300 mile run.

Also, you say a 2 lane with "little traffic", indicating there was some traffic. I don't know about you, but I feel obligated not to inconvenience anyone by driving slower than the limit, so you may have sped up a bit a couple of times until passed?

34 mpg @ 70 to 80 sounds about right for me, too.

To reiterate: I didn't do anything special accept watch my speed. 65 most of the time except through 60 miles per hour city stretches. Used cruise 99.9% of the time. The car has the ability. The largest factor was, by far, 250-300 mile stretches without stopping at all. If this is all you have on your tank, any HAH can do it.

Over the weekend, I was back to around 34 mpg - I've raised it to near 37 after today's. Back to reality....
