Pulse / Glide

[jps000]

Life without a Scangauge, how bleak it would be. The Scangauge helps train you, is quite entertaining, and pays for itself over time (NO doubt). That said, drive 50 - 60 mph and hit Cruise Control. When hilly and no cars behind, turn off cruise control and let car slow down.

If you don't want cruise control, I would drive to 55-60 and then on the flat, lightly feather back on the pedal but hold it steady (i.e. try to get Super Highway Mode); gas will be consumed (orange arrows). You can also Warp Stealth it: Feather back. When you see all arrows yellow, you are in Warp Stealth (Which is a 'glide' above 41mph, when you can achieve all arrows off).

I can't seem to get P&G right though on the highway. Every time I try, my average creeps down rather quickly. I don't have a ScanGauge or anything so I can't tell where the engine's most efficient RPM is without knowing what it's supposed to sound like.

Any pointers?

P&G on the highway is slightly different than around town or in the country. On the highway, it's more like Pulse & Bleed. By that I mean pulse up to speed then let off the pedal just enough to let the speed bleed down very slowly. Without a Scangauge, you just want to get the instant mpg bar(on the "consumption" screen) as high as you can while keeping it there for as long as possible. I have gotten as high as 76.6 on a 255 mile trip from Elkhart, IN to Ft. Thomas, KY back in May.

Actually, who needs his driving conditions? 93 MPG this afternoon, from my part time job site to my fiancee's house through the middle of Richmond, VA. To the point of this thread, this is with extensive use of pulse & glide, and keeping speeds almost entirely below 40 MPH. A major part of my strategy is seeking routes favorable for P&G. Here's the route I use for this commute, and here's the final screen shot from CAN-View to help convince the skeptics:

Awesome job Jim!

And, speaking of blinking pips, my pip was blinking for just over 150 miles this time. As for stuffing the tank without damaging the emissions controls, there is room for some expansion before damage would occur. Granted, on a Prius, there isn't as much as other cars. I believe that as long as you don't cram the tank full and go park it in the sun for the rest of the day without driving more than a mile or two that there won't be any damage done. As I already mentioned, I have over 22K miles with no codes/problems. I also live ~14 miles from the station I fill up at.

Nice try. The pumps in our area are inspected every year usually in June or July.

I didn't understand you comment, "Nice try". I wasn't trying anything! There has been several articles in the news recently about spot checks of gas pumps. A number had been found to be inaccurate and usually, although not always, in favor of the gas station. Some also implied that it seemed to occur more often with some brands than others. I don't know if it's true or not. That's why,, if you noticed I didn't make any opinion other than , which BTW means "no idea", only passing on some information.

I would like to publicly apologize for that. I guess I was letting the other comments get to me too much. It's hard to hear people question your honesty as the other poster was after working as hard as I did on that tank; it took me over a month. Again, I am sorry.

Back to you! I apologize for over reacting. I need to throw it away and take a deep breath. I'm ashamed for the way I allow myself to get emotionally involved with some of these posts that are flying around lately, not your's. And unfortunately I allow it to carry over into the next post.
Thank you.

So the average speed was ~22 mph. Not bad since the peak mileage speed range is in the 18-20 mph range.
