First 500 Mile Tank

Thar's great. With the wind gusting to 45 mph this morning, that's pretty good. P&G does take practice. The idea is if you're going to burn fuel, then burn it at the engine's most efficient range. That's the 75 % to 100% (no red) range on the HSI. So ideally you pulse up to your desired speed and then blip and back off the gas pedal so the instant mpg range goes and stays at 100 mpg. This is the glide portion. Try to keep the HSI in the 0% to 25% range. If you glide longer and farther than you did during the pulse your mpg average will go up. Here's a link to a great graphic by Ken@Japan Optimum P&G

The hard part is deciding how slow you will allow the car to go before pulsing again. (Depends on traffic and other conditions.)

I never do this in traffic and I never get in anyone's way. Always stay safe.

You can see how hills, stop signs/lights, and traffic all come into play with P&G.

All of this assumes that your engine is warm. If the engine is cold, it's going to run more often to get itself up to at least 155°. Once there, P&G is much more easy because the engine is easier to shut off.

It's counter intuitive to accelerate briskly but it you accelerate at 75% to 100% and then glide at the speed limit, you'll get good mileage.

You're getting there and making good progress. It just takes a bit of time.

Also, I allow others to go past me and turn the light green so I don't have to stop when I can.

 

par struggle,

Wonderful on increasing averages!

You might try watching energy display, not consumption, I imagine it will help. Reason is, for true glide, you want no arrows going anywhere, but from consumption screen you're probably getting EV mode (yellow arrows to wheels). You'll probably end up using a combo of those, but good to know the difference. Also during pulse for the most part you want this sort of look with the arrows:

Think mathematically - with 10 mpg pulse over .5 miles, you would then have to glide .5 miles just to get 20 mpg, or 1.0 miles to get 30 mpg. If average pulse is 20 mpg over .5 miles, then glide over .5 miles gives you 40 mpg. If pulse is average 30 mpg over .5 miles, then glide for .5 miles for the magic 60.

 

Ah yes, I should've said - the .5 miles was just for easy math, not necessarily a standard pulse distance goal.

 

One of the techies on here (I think it was Hobbit, or maybe bobwilson4, but I've forgot) determined that the sweet spot for the Gen II was around 2200-2400 rpm during acceleration. If you don't have a Scangauge, a rough estimate is to keep your instantaneous MPG at 50% + of your current speed. This means you need to stay on the energy screen to see it. I DO have a Scangauge and find it's a good ballpark guideline.

 

Thanks mikewithaprius and MJFrog for bailing me out. I'm Gen II display deficient. I knew there were some power range differences but I completely forgot about the screens. Sorry about that par_struggle. That was a great deal you got on your 09.

 

You're still doing good. Keep up the great work.

 

Congratulations! 508 miles at 49.0 indicated mpg is 10.37 gallons. I wish I was brave enough to pump as much gas in the bladder even during the summer.

 

Hit 477 miles in one tank, prius took around 9 gallons of gas about $33.00 total. I happened to look over at a pickup truck across from me at the pump and he was at $91.00 and still pumping! I probably could have pushed more mileage out of it, but I was afraid of running out of gas. The pip light was flashing and my father in-law ran his Prius out of gas after 37 miles of the warning light.
