You just never stop trolling... Can you point to the doll where the G5 Prius hurt you? The tank average has been tested against manual refill calculations to be within .5 MPG's on several fill-ups. The trip gauges match the fuel consumption history gauges, that I've shared many screenshots of, and I see no reason to think they are off. The only only gauge that is confusing at this point is the total average. I'm sure there is a simple explanation. I'll check it again to see if it's varying widely. If it is, then it's resetting after some shorter interval, OR it's frozen since it hasn't been on my main display. I could have reset it and tested my MPG's across a short trip when I first got the car, then switched to tank average, and it's been on the same "total average" value this entire time. You really need to calm down with respect to jumping to negative conclusions all the time without having the full facts. It really makes you look compromised.
This is my current tank average after almost 300 miles of driving. I have no reason to believe I will not get close to 680'ish miles/10gals of gas as long as I continue to drive in these current mild conditions. Unfortunately, the hot weather is coming back so the fuel economy will likewise be pulling back again. Also, if I find myself parking the car for hours with my dog inside enjoying the AC, like I did last tank, then the tank MPGs will come down because of that, just like they did last time.
They're just pointing out one of your many hyperbolic and incorrect statements. You sound unhinged most of the time, truly.
from post #105 back on page 5 https://priuschat.com/threads/2023-prius-le-problem.240205/page-6#post-3382614 ----- Hammersmith said↑ Total measures lifetime from whenever you manually reset it. If you haven't reset it(pushed and held the OK button while on the Total screen) since you took possession, then that's your average over however many miles you've got on the car right now. ------- If you want to make sure, at 10K miles when some ( Trip A and B ) of the gauges flip, check to make sure that is not what is happening on the gauges you want to keep lifetime. Pictures before 10k and after 10k is the only other way I know to keep records of the gauges that flip every 10K. Pics also help if a gauge gets reset by mistake, while taking pics of gauges for records (lol) ......
High enough for many miles of low speed crawling can explain. Like around ports and ships. It may not have been reset since it came off the line. Perhaps never been reset could cause an error.
So I have read the manual on this, and even when I am in HV mode using the "leaf" icon I don't seem to be able to get to the fuel information that you are showing. Wondering what the sequence you go through to get to various fuel usage data? If you are able to post how you get there? Either an operator error (me) or there is some glitch in my software that runs this data.
OK, never mind. I got it. And it is a ridiculous implementation of how to get driving fuel consumption data. You have to go from the leaf icon back through about 10 different toggles in the gear icon to where you can change how the fuel data is displayed. Mine, btw, for total average shows 75.7 mpg. Real? What does it mean. I wonder if it somehow factors in the amount of EV driving, and is not a true reflection of actual gas mpg? Mine is based on about 2,100 total miles, never reset this thing, couldn't even find it The car is great but this info display and credibility stretch my patience and wonder about the value of it. Difficult to use this info on a trip where you turn off the car to get the trip info for the entire trip too, because it auto resets every time you turn off the car. My 2016 VW Golf was much easier. It gave you mpg, miles driven, average speed, total time AND it didn't immediately reset so if you are on a trip, stop for coffee, you still know on that trip what you were getting. Rant done.
There are many more MPG features than you are aware of. I have posted about a lot of it on here in varying places. I can find out exactly what I need between the MID and multimedia display.
Sounds good. I will probably just be happy knowing I get great mileage and driving mostly in EV mode when I'm not getting great mpg. And, I will on occasion just do a manual calculation on a longer trip, that is, fill the tank, drive miles, refill the tank, and do some math. Easy.
Pg. 104-105 of the manual. Go to the history page of the vehicle/trip info screen. Click update when you start your day and you'll have your fuel economy displayed brightly and clearly at all times no matter how many trips you take. It will combine them all. And it will do it in glorious 199.99 format. I believe it resets the next day and then prints a bar of the "previous day's" MPGs. I always hit UPDATE to start the day as I want to know my daily MPGs. Trip MPGs of course, are always displayed when you turn the car off.
Whelp! Mystery solved! Hitting the update button on the trip information/history page also resets the total average gauge. So there's a convenient redundancy for those who'd rather have the info above the steering wheel, or on their multimedia screen. But I don't think the total average gauge measures in the 100's like the history screen does. So we are right where we've always been: the G5 gauges are quite accurate, and more accurate than the G4's.
This was a slight exaggeration on my part. It only took 3 button clicks to access the menu that allows switching between the three MPG monitoring options.
Just to clarify... So you're saying that hitting the 'Update' button on the infotainment screen has the same effect as holding the 'OK' button on the Total Average MFD screen? And that you've pressed the 'Update' button several times since you bought the car, so your current number of 75.9mpg is not months old but probably only days old? If so, the probable next best step is to avoid pressing the button for a month or three to get a good long-term reading to satisfy our local curmudgeon. BTW, I'm sitting here very jealous in my Limited AWD and my high-40s. Not so jealous to give up my PVM, ventilated seats, and AWD winter security, but jealous nonetheless. I'm picking up a few tricks to get into the low 50s, but my terrain and driving needs will never let me get much above that.
No, I won't be changing my habits. There's nothing else to find out. I use the trip/history function as a daily MPG gauge. The engine off trip summary for individual trips. And the tank gauge for tanks. I've got everything just the way I like. I'm currently averaging around 69 MPGs on this tank. And I've demonstrated that gauge to be accurate within .5 MPGs.
To play devil's advocate, you're not necessarily averaging 69(nice) mpg unless you're driving nearly the same amount of miles per day. For instance, consider this situation: Day 1: 100mpg over 1 mile Day 2: 50mpg over 100 miles If you just average the daily totals, you get 75mpg*. But that's not the true average mpg. The true average would be something like 50.5mpg**. *(100+50)/2 = 75 **[(100*1)+(50*100)]/101 = 50.495
I wonder if that actually works that way? Doesn't make sense to me that you would have to hold for 3 seconds on the 'OK' button to reset the Total Average on the MFD but just hitting the update on the trip info on infotainment screen would do that also. And if that is the case, the manual should, where it talks about the 3 second hold, also mention that this update on infotainment does same thing. I am not impressed by the complexity of these features. There should be some kind of high level basic information provided, and then for the people who really want to dig down (like those on this forum), a deeper dive option. I get that the complexity of the car has to be that way and in fact is one of the reasons it is so efficient, but the user interface does not have to be.
I wonder the same thing. I'm going to be driving in a few hours, so i plan to test it then. Should be super easy to confirm/refute.
What? No. This is the average fuel economy I am earning. When it's time to fill up for gas, and your tank average says 60 MPGs, you will have around 580-590 miles driven refueling 9.5-9.8 gallons of gas.
