Gas gauge acting funny after fill up

[jayhof]

Question about the gas gauge after fill up gas gauge acting funny. I just got a 2007 Prius and I have filled it up 3 times so far. The last 2 tiles I filled it up the with about 8 or 9 gallons of Shell fuel. I was kinda surprised it only took 8 to 9 gallons because the fuel light was flashing so I tried to top it off but was only able to get about 1 dollar in. now this is the strange thing that happened.
The first time it happened after driving about 10 miles the first line went away. I turned off the car for about ½ hr and then drove anther 10 miles and noticed the fuel light was flashing as if it was empty. I took the car to the dealer and showed them but when I turned the car back on the gauge went back up to full.

The last time I filled it up I topped it off and when I got in the car the gauge was flashing as if it was empty foe about 20 miles and then went back to full. Has anyone noticed this?

Thank you,
Jason

At least since cold weather hit, I've never been able to get more than 8 gallons in, even after it's started flashing.

The volume appears to be normal. If the gauge is showing low and I know the tank is full I wouldn't have been concerned about running out of gas but my next trip would be to the dealer for some warranty work.

No, I haven't noticed that but I did notice that after I filled up and drove only about 40 miles, the gauge was down two pips. It seems like it went down too fast from being "full." I too have a 2007 and am only about my 4th tank of gas. My MPG has ranged from about 42 MPG on the second fill up to 33 MPG on my last one. I'm really surprised at the difference. I'm supposing it's the cold weather and the fact that the 42 MPG had some highway miles on it. Before purchasing this car, I was under the impression that the Prius got the BEST mileage in town which I guess was not correct.

I have had my 2007 for two months now here in Illinois. The colder it gets, the harder it is to get a "full" tank. Today, when I filled up (8f temp) I was able to squeeze 9.956 Gallons in. It clicked off the first time at 7.5 gallons. What I did different this time was to pull the nozzle out a slight bit and tilt the tip up. Then I started filling at a slower than usual rate and squeezed in an extra 2.456 gallons in. Stopping at the first click, especially in the cold doesn't seem to work.

I had the same problem and thought the same thing. What I did is took the current mileage on the odometer and divided it by the total number of gallons that I used since I got the car. My average was 46.2! Don't stop at the first click when it is cold.
Hope this helps and don't worry, you bought a GREAT car! You'll see.

One of the few things we all seem to agree on is that the EPA numbers don't represent realistic driving. Environment, terrain, and driving habits all influence the mpg. When it's colder the ICE runs just to keep itself (and probably you) warm. The technique with the best ROI is to block the grill. (Search for "My first day with a blocked grill".)

In slow stop & go traffic the electric motor will drive the car (until the battery needs charging), hence the higher city EPA estimate. One doesn't need much power to maintain a constant speed so with a little practice one can get high highway mpg.

The first 5 minutes of any drive will be low--around 25mpg as the gas engine warms up the converter and itself.

Don't get freaked out over the "guess guage". Some pips go fast, some slow.

The best advice is to just enjoy driving the car.
