MPG declining to a disapointing 44 MPG

Fuel economy complaints/queries? Please copy, paste & answer these questions, esp. if you're new | PriusChat

Where are you located? Are you quoting grossly inflated Canadian and/or European mileage ratings?

4.5L/100 Km is only 52.27 miles per US gallon, which is already way above the US EPA rating of 42 miles per US gallon (Compare Side-by-Side). 4.5L/100 Km does translate into 62.77 miles per Imperial gallon which is worthless to us Americans. We don't use larger Imperial gallons here.

 

I still wonder if it should be made compulsory to enter Location in the profile. Then we know where people are, what stats and figures they are or are not using and focus the response accordingly.

 

And not answering the questions asked in the thread and repeating the same posts two or three times isn't helping either.

So you're disappointed in a 31% drop in efficiency. I'm disappointed you're not answering the people on here who've asked questions to try and help you! I wonder if your Toyota dealer had a similar response?

 

It is probably because you are repeating the same thing over and OVER and just cluttering up the thread with useless repetition.......while NOT responding to the questions posed in an attempt to give you some good information.

It also could be that the forum software in doing it to you; sometimes posts double and sometimes they don't post at all.

Your situation is not unique. There are multiple threads on here about "poor gas mileage".
One was even posted as a link in a reply to this thread.
Please spend some effort and look at the previous discussions.........and then come back here with specific questions.

 

are these imperial gallons or something? 44 u.s. gallons sounds about right for the v.

can you give more detail? tyre pressure, gasoline, 12v battery test, mileage, many things affect mpg's.

 

This is not a "chat" Alan.

It is a public FORUM where people leave questions and comments and others respond with their ideas, experiences and opinions.

I, for one, have a reasonable expectation that new users will look around at least a little bit to get familiar with how things work before they just jump in with both feet.

Apparently you don't agree with that method of operation.

There is a lot of information already on here. READING those previous discussions is pretty simple, painless and probably would give you information that is useful too.

It seems rather rude and disrespectful to criticize the new crowd that you have just tried to join.
Not a very friendly attitude.

Good luck getting help.

 

i think you would find it helpful to provide more detail here and answer questions. dropping mpg's is not usually simple or black and white. you will find many friendly and helpful people if you just give it a chance. all the best!

 

Your complete lack of response to the legitimate questions that have been asked of you, makes us think the same of you.

Hundreds of new members have previously asked similar questions, so Cwerdna wrote up the questionaire linked in post #2 to help make sure most of the likely problems were addressed. If you cannot reply to any of that, then don't expect much friendly help here.

 

I'll bring the popcorn if someone else brings Cheetos.

 

Don't despair. Whilst our v is great normally, if my wife only does 900m each way trip to school it can sit at 6 to 8 l/100km. I finally did a sanity check in my 2012 yaris the other day and I got 14 l/100km one way and 10 l/100km for the whole trip. Prius v wins again!

 

What we have here, is a failure to communicate. Hey Rai, try doing a search on this forum for "Bad gas mileage", or, "Poor MPG", or, "Dropped MPG", you get the idea. The search box is in the upper right hand corner. I bet if you search those word phrases, you will find a bunch of info and ideas on what might help you get better MPG. Our First fill up on our NEW Prius 3 calculated out to only 41.6 mpg, and even the dash stated the same thing. But for us,, living in the very hilly Central Coastal California area where its always up, or down a hill, I am pretty pleased with that. Our previous 2013 Dodge Dart window sticker stated it should have gotten 27 city, 31 average, and 37 highway, yet it would average 22 - 26 all the time with 75% highway & 25% city driving. So your location of driving can make a huge difference. Plus driving style too. Sounds like others said temperature and weather can be a big factor. Have you checked your tire pressure too???

 

Because you posted at least one duplicate thread about the same issue. The moderators likely spotted that and deleted them or merged them w/this one. Please don't post dupes. It's pointless.

Yes. Please answer Fuel economy complaints/queries? Please copy, paste & answer these questions, esp. if you're new | PriusChat in this thread.

Without it, we have little to go and can't provide any meaningful help. I'm unwilling to help those who can't help themselves. Prior to the questionnaire, I grew very tired of people posting mileage complaints w/scant or no details (like the OP's). I and others would spent a lot of time and energy writing a reply, asking for details, posting speculation (due to lack of details), etc. often to to have the OP (original poster) to never return.

Or, often, there was WAY too much back and forth (person A, asks a question, we wait for a reply, person B, C and D speculate, E asks another question, etc.) It wasn't efficient and was frankly a waste of time on everyone's part.

For all we know, the OP's trips have gotten much shorter (short drives kill mileage), the weather has gotten much colder (hurts mileage), has changed to tires that have much higher rolling resistance than stock (also hurts mileage), has underinflated tires (take a guess), has overfilled oil, etc. But until the questions get answered, we have no idea.

If you want help, please answer the questions. There are many folks willing to help. The reply might even be "yep, that's totally normal for your driving conditions and trips."

 

What a ridiculous accusation! I am not and have never been employed by Toyota nor any car dealer. I suspect that's true of virtually everyone one here. There are a couple Toyota corporate employees who I have personally met who post under the handle Prius Team.

We're trying trying to "confuse" or hide anything. We need to FIRST establish some baseline information. We have virtually none right now, from you.

I can only guess you're in Canada since you mentioned metric consumption figures and what I believe are useless (to Americans) Imperial gallons.

If you'd like some background info about the US EPA test along with inflated Canadian mileage test figures, see below:

This forum, namely, Priuschat is NOT run by Toyota in any way shape nor form. Your anger is misdirected.

Again, please calm down. If you want help, we need more info from you, via the questionnaire. I am not personally willing to spend time speculating and going back and forth on questions until you've answered Fuel economy complaints/queries? Please copy, paste & answer these questions, esp. if you're new | PriusChat in this thread.

What's on the Monroney sticker is not a promise that a vehicle will get that mileage at all. It's simply the result of the EPA test cycles and calculations, most of which aren't even validated by the EPA itself.

Car and Driver: The Truth About EPA City / Highway MPG Estimates | PriusChat discusses what goes into the EPA test.

Heck, even Hyundai screwed up, resulting in inflated figures (FAQs for Affected Models & Compensation | Hyundai MPG Information). Ford basically took advantage of a loophole and claimed they didn't even test the C-Max Hybrid, and instead put on a higher figure via the "general label rule": Ford: We didn't overstate C-Max Hybrid mpg, low numbers were a surprise.

4.5L/100 Km = 52.27 miles per US gallon = 62.77 miles per Imperial gallon (pretty darn useless and meaningless to Americans)

Google makes for a great unit converter for the units we use here: use Google to easily convert confusing/meaningless (to you) mileage amounts | PriusChat.

I do see the above L/100 km figure at TOYOTA CANADA: Language , which again, is a useless inflated Canadian mileage test value. I doubt the "average" (non-hypermiler) Prius v driver in the US and esp. Canada would regularly achieve that combined mileage.

42 miles per US gallon (Compare Side-by-Side) EPA combined value is more realistic. That translates into 50.44 miles per Imperial gallon or 5.6 L/100 km (also meaningless to Americans).

 

Relax, Toyota isn't pulling the wool over anyone's head, this forum has no motive to deceive you

Dis connect the 12v battery for 5 minutes, now re-connect it, start over, there's no conspiracy, it's a car, it takes gas, less than some more than other's.

 

RAI - thanks for the good laugh!

 

Is it possible that somehow your mileage display units got changed?

Myself, I don't trust the darn thing, keep it on the ever changing setting just for giggles, compute my mileage based on gallons used and miles driven after every tank fill up using fuelly.com (US, sorry about that. Wish we were metric but that is another discussion.) and don't value any one tank fill reading because the fuel shutoff at any pump can be different from day to day or pump to pump. I look at the average over lots of fill ups. I do just about US EPA figures on average depending on how, when and where I drive.

 

alrighty then.
