There may be a lean burn factor cutting in under these conditions as well.
I think you are right. There is less load on the engine, but it is too close to idle and so uses more fuel! Pulse and glide at the slower speed is pretty much always more efficient though, but probably not something to try in an auto.

See this page here.

EGR is typically not employed at high loads because it would reduce peak power output, and it is not employed at idle (low-speed, zero load) because it would cause unstable combustion, resulting in rough idle.

All of Newtonsfirstlaw's thread starting comments are right on.

The difference in fuel economy and risk of death in a collision between 45mph and 75 mph are HUGE.

I don't think that a "turtle parade" on the interstate would be the best thing, but I do like the concept of a "Green Lane". Sort of a slow-and-steady carpool lane would be great.

On the interstate, as long as you are in the slow lane, and people can pass you, I have no problem driving a little slower (55 not 40!)

Lately I have been doing lots of driving on country roads at 45 mph with not too many stop signs. Fuel economy is good and it's a lot less stressful than being on the interstate.

I also like the "I don't speed to red lights" bumper sticker idea. I always just let off the gas when I am getting anywhere close to a red light, most of the time, the light turns green before I coast up to light and I just roll right through. Sure beats burning gas to the light, wasting brake pads, and then wasting gas again to pull away.

You can do the same thing by letting off the gas when exiting the interstate. There is always a stop sign or traffic light at the end, so why bother to speed to it?

Thanks! I hereby give 100% rights to the Ecomodder website (since it's your E anyway, ). I am sure youz guyz could make a more elegant version, with or without the rest of the words.

With the words "in the turtle body", I'll bet you could make a nice T-Shirt.

It's better with the lower case e.

Not everyone can see that the space around the turtle wrench head is an E - it's sort of a weird optical illusion.

I agree, the e is hard to tell, because you are drawn away to the fact of that cool turtle! The word Ecomodder follows the E symbol anyway on the website's main banner, so might as well do so on the turtle. Is there anyway to see how it looks outlined in black? If there was any merch, I'd buy all of it (well... that I could anyway). Hats, keychains, shirts, bumperstickers. But I wonder what exactly it would take to create all of this :/ . I'd love to have the bumper sticker on there first off though.
