800 mile per tank challenge

I am no expert, but from what I understand, Octane has nothing to do with energy content. There should be no difference between 87 octane and 92 octane. The 92 octane can support much higher compression ratios however.

 

That's absoluely correct, however, one way to add octane is to add higher energy aromatics. So you could have better energy ...just not guaranteed.

 

All righty then. How do I get my hands on some high quality aromatics? Sounds like they should be illegal.

 

Pretty expensive these days I thought about fiddling but expensive. Toluene/Xylene typical. I think STP.
92 octane E0 is the best shot at it

 

Yesterday I posted my first tank on Fuelly. Then I looked under 2016 Priuss and didn't see my entry listed. I went back today and got the same result. Then I read the comment above the distribution chart:

"Below you can see a distribution of the fuel-ups with 1 outliers (5.88%) removed."

So now I am an outlier! I can understand the need to do that after only one tank, but maybe after a few tanks Fuelly will take me seriously.

 

Tell them and point out your total mileage. If it was a 100 mile fillup that could be explained by a pump difference, but a full tank is an entirely different story.

 

Statistic maniacs. I've seen that a couple of years ago with Spritmonitor rejecting a tank of 1.5l/100km with a Prius PHV. It has changed since, because of complaints.

 

...bummer!

 

Patience my friend. The grinding of bureaucracy is slow but inevitable.

Indicated:
873.4 miles indicated/11.438 gallons pumped = 76.36MPG
81.8/76.36 = 7.1% error (Not corrected for Odometer error)

Corrected (with Odometer error of -1.9% (measured via google maps on 3 occasions):
873.4*1.019 = 890.0 actual miles/11.438 gallons pumped = 77.81 MPG Corrected
81.8/77.81 = 5.1% total error.

Fuel warning came on at 794 miles.
Range went to zero at 844 miles.

Driving time was 25 hours and 45 minutes, 34.56 MPH average speed
56% in EV mode. Spring has sprung in Raleigh.

 

Pretty amazing I would like to see what the highest miles for one tank is for nonstop highway trip. I drive 24 hours straight to Dallas every year.

 

The primary determinant is highway speed. We are getting enough information about the Prius that we may soon have an effective trip planner. From what we're seeing so far, take these numbers and add 10% to get a rough, rule of thumb . . . for now:

So if your speed is say 80 mph, adding 10% would be:

• 40 MPG * 1.10 ~= 44 MPG
• 44 MPG * 11 gallons ~= 484 miles

You'd be looking at about 500 miles without reserve.

Thanks figuring 75mph which will be on some long stretches but overall average is closer to 63 mph so around 50 mpg so probably closer to 500 miles between fill ups. Figuring I am not going to let it get to the warning light. Still better then my 300 miles between fill ups.

 

Remember the car burns the gas so use its cruise speed which should always be higher than elapsed speed and even what shows up on a dash trip meter . . . unless you reset it upon reaching cruising speed.

Now the Gen-4 may be too new to show up in rental fleets but I'm sure the Gen-3 is available. You might consider renting one long enough to find out if it works for you . . . knowing the Gen-4 is a much nicer ride (not that I have any direct experience, yet.)

GOOD LUCK!

Thanks. Looking for better gas mileage than my current vehicle. Once made the trip in a 2012 Honda Fit.

 

I will post details tomorrow.

 

A 1000 mile tank already? That didn't take long. Summer hasn't even arrived yet.

 

Maybe for you. With snow and slush on Stevens Pass today, and a winter traction tire advisory, our AC season is still a fair way off.

 

Wow, can't wait to see the details.
