95 miles into my new tank of gas. 59.2MPG. I was so pleasantly surprised I was looking for some big rigs on the road for hypermiling and slipstreaming. But I decided against it. I thought the good old days of 58MPG tanks were over.
I think we are going to need to see a screen shot of your Trip computer. I would also like to see your odometer with overall mileage since new. There are arguments that the Prius trip computer isn't accurate and the pump is what they go by.
Yeah, the trip computer can be off by as much as 10% depending on what season it is. Calculated I'm close to 71 mpg. Trip shows anywhere from 72 - 75 mpg. What to put first in a fuel economy spreadsheet? | PriusChat Mine is #11 on this post.
I looked at your spreadsheet. You listed the EPA figures of the Prius 2 Eco 58/53MPG. Which Prius 2017 model do you have. The Prius 2 or the Prius 2 Eco. Each state used to test gas pumps to make certain fuel stations were pumping 128 fluid ounces of gasoline in each gallon. Do you want to know why? Because in the old days they could nickel and dime the customers by cheating the pump in the favor of the gas station. With gas prices being so high today it's more like a quarter here and a dollar there. When people say I trust the pump because the trip computer could be off as much as 10%. I defer to what I wrote above for the possible reason. So unless you have a gallon milk jug or a fuel can for exact measurements. That is why I asked for a screen shot of your Prius ODO which has the overall MPG for the life of a 4th generation Prius. Science would call it a baseline measurement tool. I consider myself a professional Prius driver. I am not big on taking notes or building excel spreadsheets to document my MPG. I put only a little effort into achieving good fuel efficiency. I do have a personal handbook on techniques to maximize fuel economy. Some are known tools of the trade and some are proprietary trade secrets. The efforts to achieve exceptional fuel economy are not worth the effort in day to day driving. Basically the novelty wears off and the design of the Prius computers balance out the achievable fuel efficiency quite well already. So if you would kindly post a photo of your Prius ODO which has the overall MPG next to it. I think your #11 post had somewhere between 26-27,000 miles on it. Also please clarify if your Prius 2 is a standard 2 or an Eco model.
Lol, you think I'm BSing you? I have a Two Eco. ODO just rolled 27033 as I write this. And I can't remember the last time anybody was filling up using milk jugs to make sure they were getting the correct amount of fuel they paid for. I kinda sorta trust Costco more than the corner gas station.
The Two Eco gets 4 MPG more than the two, three or four Prius. Let's see a screen shot of your trip computer with the ODO and overall MPG since new. I wasn't implying that people should use milk jugs to measure their gas.
You don't seem to understand how the overall MPG works. It gets reset every time the trip meters get reset. I reset Trip A monthly and Trip B every fill up. Not everybody uses them the same way you do bud.
I am one or very few that knew to use the "B" trip odometer for lifetime MPGs. Displayed only - not calculated of course. I reset my "A" trip odometer and "update" my ECO app screen every fill up. You would not know to do this unless you had a history with a Prius. Fortunately the "B" did not reset when my battery was replaced. The only issue is that the trip odometer cannot display all of the values so it looks like it zeroes out every 10,000 miles - but it does keep all of the data.
The Gen 4 Prius has a cycle button on the steering wheel for trip information. If you cycle through trip A, trip B, current trip and miles left on current tank of gas. You should discover that when you cycle through to your Odometer screen. It will have to the right of the ODO your average MPG for the life of your Prius. That is what I want to see on your Prius 2 Eco, bud...
No. The MPG shown there is the data since the ECO screen app was last reset. At least that is what my 2016 shows. Test it - see if that value matches your ECO app screen value.
you reset on the MFD screen. The ECO app has three choices - past record, trip information, and energy. On the past record screen, you can "update" the data which will start a new "stack" and begin measuring MPGs. if you don't have these options then maybe you do have lifetime MPG displayed on your trip odometer.
When you cycle through your trip computer. When you get to the ODO screen. Do you not have MPG to the right of the odometer reading? Are you saying you can reset that or regularly reset that MPG?
Yeah, I also update the past history on every fill up so it shows me how every tank does. That number you so desperately want to see is linked to this screen. You're just gonna have to take it on faith that my numbers are correct.
