700 miles on first tank of my own!!!

[DrJon]

Filled up last night for the second time so this was first official tank of my own. (Dealer fill tank not sure of their technique, or how full it really was). I used the same pump at the same station as my first fillup (after 604 miles). I had initially put in 10.795 gallons. This time I drove 701.2 miles. I was sweating it a little on the last 129 miles (reset trip B when I got the beep and last pip began flashing), but thanks to Bob and all the PC people I was fairly confident I wouldn't run out of gas if I kept my avg. up.

Now for the 800 mile tank attempt!

Oh, I resolve to be aftermarket computer (Scangauge, MID, etc.) free! We need a separate category for those who "cheat" (just kidding) and those who keep the virginity of the ECU (no tapping allowed).

Sweet!

Well done on the tank but you earlier posting gave the average speed as 25 mph. This is what I need for the updated 'mph vs MPH' chart:


If folks will post:

• indicated MPG
• actual MPG
• average speed

I'll add their data to the spreadsheet and post a "Thank you" when it is done. Over time, we'll get a better and better picture of what this car can do and begin to understand what leads to 'better than average' performance.

BTW, I'm with you for this first year. I need a baseline performance of my wife's car with no 'tricks.' Careful records makes it possible to understand what works and what could be better.

Understand that I have no problem with PnG posting PROVIDED we also get the equivalent, steady-state speed. This allows us to quantify the two but more importantly, to understand what the car, not the driver, does.

Thanks,
Bob Wilson

When you filled up did you fill to the top of the filler neck where you could not get another drop of gas in the tank?

Because, from personal expierence, when I filled up my tank once when the pump at low setting shut off I still put nearly 2.4 gallons of gas in the tank where it reached the max point at the top of the filler neck. I am sure that the 2010 Prius tank is over 11.9 gallons at max fill capacity.

excellent work, when you get 800 I'll really be impressed as I don't think I have 800 in me. As soon as I start doing real good, avg over 70, along comes a bunch of short trips with several hours between them, that shoot me down.
Wait till you get it broken in, you may have an 800 mile tank in you. Doing so well right out of the box is impressive.

No, I do not fill up to top of filler neck. Not that brave with the cannister thing and all. I put 11.541 gallons in it by pumping full speed to about 7 gallons, then lowest speed I could go to first click off, wait about 20 seconds, then lowest speed again till next click and that is it. For me, at the pump I use (always the same one at the same Chevron), this second click comes very quickly. The concrete at this particular pump seems very flat. I should pour out a glass of water there and see how flat!

I should pay attention to when first click occurrs and see how much to second click but my feeling is that it is not much at all!

there we go... that's the best way to do it according to the article I read in a car magazine a while ago based on the opinion of several car engineers. I also do like that...

i dont think that is a good idea when it comes to toyota cars. my family had toyota cars and my mom loves to do what you do and in the end it will give you the engine check light due to that. you should stop at the first click of the gas to prevent this. someone confirm this but this happened to my moms avallon and my cousin's tundra.

Very impressive! I didn't know that was possible. Amazing!!

Actuallly, Wayne and Ken can really kick my @#$%! I think Ken (in Japan) has done a 1000 mile tank and I'll bet Wayne can easily do a 900. I may try for a 800, but without advanced training by a pro hypermiler and maybe some extra gauges, don't know if 900 is possible by me! Sure is a fun game though!
