#45 of 114 Just happened to me, 2008, 3500 miles by scottc3

I have not read this part of the forum before, but was somewhat aware of a 'gas tank' problem. Yesterday I was down to 1 bar, and on my Prius this means I have 3 gallons left (about) - based on the other fill-ups. I put gas in, but it only took 6 gallons. The pump kept shutting off. I told the service guy at the gas station his pump was faulty, and paid for the 6 gal and left, then went to another station. Same thing, got in 2 gal there, and the pump started shutting off. I was filling very fast, and will try it slower next time, but it's not happened before this, and I fill fast all the time. If this happens again, I will take back to the dealer and see what can be done. I have many records of filling up the car. It's about 75 degrees here in San Jose, so the cold is not the issue. And it's worked fine until now.

That is pretty much what happened to me except I had 5 bars on the gauge and it wouldn't take any gas so I didn't know if I was full, half full or less. The problem seems to have disappeared as strangely as when it appeared. We going on a long drive soon and I'll keep track of the gas situation and report back.

No neither statement is correct.
 
The Prius only needs basic clean 87 Octane. Anything else is a waste of money.
 
The dealer is wrong. That's not too uncommon. Most sales people are as aware of the Prius as they are of the Space Shuttle.....and I sell Prius'. 'B' is only for engine braking in downhill situations so that you don't ride the brakes all the way down. There's no other purpose.

#48 of 114 MPG Question by rolin

May 16, 2008 (2:09 pm)

Hello to all
 
 I have concerns about my MPG and I would appreciate any help you might offer.
Here's the deal. I purchases, and love, my 2008 Prius with package #7 3 weeks ago. Since that time, I have gained insight into the "Bladder" type of fuel tank, etc, and understand how to fill the tank, which by the way is very different than filling my Pathfinder, which I do Not miss...
 
When I bought the car, the gas indicator had all bars lit, indicating a full tank. At 5 bars, I filled it up, with 5.013 gallons and set the trip A odometer to track my MPG. At 3 bars, the next week, I was able to fill it with 6.06 gallons and noted the Trip A odometer at 323.3 miles. I thought that I was supposed to divide the miles driven (323.3) into the 6.06 gallons. I was under the impression that I was getting approximately 53 MPG.
 
What I am seeing now on my trip odometer is 168.7 miles driven, with now bars indicating 1/2 of a tank (5 bars). My consumption meter is showing today an average of 47.2 MPG at the 47 miles that I drove today.
 
I am confused and I hope I don't sound a a bit ignorant here. How do I track my MPG, based upon the above MPG information, what does it seem to you that I am getting MPG? Can I be getting only 30 mpg? I don't think so, but the wisdom and knowledge I have see here is impressive.
 
Many thanks
 
Linda

On occasion I have filled my tank('06 model)to the brim and the bar gauge has read 2 bars below maximum. It usually reverted to the correct level but I never established a correlation as to how many miles I drove before it did. I don't understand why it happens, just a quirck I suspect.
 
If you filled the tank before the fuel level gauge reverted then that might be the cause of your low mpg reading. Absent a major change in driving conditions it is unlikely you would go from 47MPG to 30MPG. Whenever the "quirck" happened to me it wasn't reflected on the elapsed consumption gauge. Hope it makes sense to you.

#50 of 114 Bladder issue - mine seems OK now. by sergelbergeron

Firstly - I am now filling it up v e r y s l o w l y.
I just returned from Florida (Ontario - Florida) - so I did about 3,500 miles - - my highest fill-up was 9.559 gallons and I know I was on the low of bar 2 - I never let it go to bar 1, since I ran out of gaz. Most of my fill-ups are around bar 3-4 and I was putting in about $23 - or 6.4 gallons - on my total trip - going between 55MPH and 77MPH - I took 72.7 gallons for an average of 48MPG. I think this is higher than the indicator was showing. On one occassion, I did over 100 miles before the first bar disappeared.
 
Anyway, I love my Prius, I know I have the most ecological green car out there - (even better than those Smart Cars or those Mini's)
 
I am not happy with big SUV's burning all the gaz. I don't mind $4. a gallon - maybe there will be more smaller cars out there - more hybrids. When we look around - with all the big SUV's - with only one person in the car - it is a shame.
 
Some day, driving a big car alone, will be like - smoking in a restaurant - it will be forbidden. We need to take care of this planet - Sorry - now I will go with the TreeHuggers web sites ....

#51 of 114 Been monitoring gas tank / fills by scottc3

Jun 06, 2008 (8:47 pm)

I posted above (sc) and now again. In my last tank, which did not fill up 'on it's own' (shut off around 7 gallons - and I know it should have taken at least 9), I kept putting in little bits of gas, until I thought it was full. Today I was on 420 miles and had 2 bars left. This has never happened before, at 420 miles it's usually on the last bar and it's blinking at this mileage. (and I think I have 2 gallons left in the tank - which I know now I do not). So, this clearly means the tank was not getting full in all previous fill-up attempts. Today I filled up, and I filled slowly with the gas nozzle barely in the tank. The gas overflowed, onto the ground - just a bit, but the tank was totally full. It took 10.8 gal today, with 2 bars left on the indicator. We are all assuming when 'we think' our tank is full, we are at 12 gal. I think this is a mistake.. many of us are not getting 12 gallons into the tank when the pump stops letting gas in the tank and shuts off. Here's what I have been monitoring.. each bar and how many miles.
 
Bars.... Miles
1....... 130
2....... 158
3....... 183
4....... 209
5....... 257
6....... 310
7....... 353
8....... 420 Filled up here 2 bars left and it took 10.6 gal.
9
10
 
It will be interesting to see how many miles I get on this 'full' tank. I'm not sure the tank has ever been full before.

It doesn't really matter what the bars say. It's just a simple gauge. You know exactly how big the tank is because the manufacturer tells you the exact size and you know how many gallons you just put in it. The gauge could be off by 1 bar easily and I believe the Prius has a bladder gas tank so you will have variables as to the size of the gas tank.

#53 of 114 The point here is... by scottc3

Jun 07, 2008 (2:49 pm)

Yes, we know we all have basically 12 gallons. The point is, are we filling the tank to 12 gallons. Many are not able to, and don't know where the '12 gallon mark' is, because the gas is shutting off early. The indicator marks may read 'FULL' when we only have 10 gallons in the tank, or 9 gallons in the tank. If this is the case, I would expect the 1st bar to go off - indicating fuel used - before 100 miles, at maybe 50 miles.. then you know the tank was not full when you stopped filling. I will know, for my car, on this next tank, when I actually overflowed my tank by accident. But this will be a good gauge for me. If I now travel 150 miles before the 1st bar goes out on the gauge, then I will know I was not filling my tank before.
 
I would also assume, of course it's a guess, that all gas indicators are about the same.So others should get close to this also - and I would be interested to see what others are getting on 'each bar'.

#54 of 114 Toyota Prius is a SAFETY HAZARD by priusdar

Jun 07, 2008 (7:06 pm)

I have just read several stories of concern on: http://www.consumeraffairs.com/automotive/toyota_prius.html. There are MANY other websites that speak to Prius problems: http://www.consumeraffairs.com/news04/2008/01/prius_winter.html - http://townhall-talk.edmunds.com/direct/view/.f1205be - http://www.hybridcars.com/forums/2008-prius-fuel-tank-capacity.html - http://priuschat.com/forums/prius-main-forum/10650-prius-fuel-tank.html - http://www.greenhybrid.com/discuss/f10/problem-putting-gas-prius-1611/ - these are just the ones I have stumbled across.
  
I am SICK to my stomach. I have TRUSTED Toyota for YEARS to provide a SAFE and RELIABLE vehicle. I traded in my 2007 Toyota Touring Avalon on my 2008 Toyota Prius ... NEVER even giving ONE thought that I was buying an UNSAFE and HAZARDOUS car. (Boy do I ever wish I still had the Avalon ...)
  
I have personally experienced the FAULTY gas tank design, fuel gauge that is ONLY at best a GUESS gauge, gas and air bubbling out when you TRY to fill the tank and the sheer fright of WONDERING if you are going to run out of gas when your tank shows a few bars left on the gauge.
  
Now, I am TOTALLY DISGUSTED to have discovered that my car very well may QUIT functioning in snow or slick conditions!!! I live where snow happens rarely, but rain happens ALL the time! I do drive in snow conditions often ... luckly is seems, not yet in this HAZARDOUS car.
  
I was SOOOO very EXCITED to take my new Prius on our recent road trip!!! Now I am nearly in tears realizing that I am driving, "literally" ... AN ACCIDENT WAITING TO HAPPEN ...
  
Luckily, as of today, there has not been any physical damage. Unfortunately, emotional damage and loss of faith in Toyota has happened.
