Got our Prius on June 1, have about 1,900 miles on it so far. I've read about the non-linear gas gage and didn't worry because I never had a car where the gage was uniform. So anyway, I been getting results like I've read on several postings, 100-120 miles on the first bar then 30-40 miles on each of the successive bars.

OK a couple days ago, I gassed up but got a little aggressive with the pump. I set it to its slowest delivery rate, then when it clicked off, I give it a few extra clicks. Well this time I must have clicked a few too many times because when I pulled the nozzle out BUUURRRP and about a quart of gas comes gushing back out :oops: . So I wash the car and go on my way, no problems other than wasting enough gas to idle a Hummer for nearly a nanosecond. But since then the car still runns great, but I now have 206 miles since that fillup and still 10 bars! :shock:

Did I just overfill to an extreme and it's just going to take longer for it to come down, or could I have jammed the sensor and will have it stuck on full?

Doesn't anybody fill up normally anymore?

It's possible, but doesn't seem that likely, that you jammed the sensor. It's also possible that you overflowed into the vapor recovery system, filling the charcoal canister with gasoline. I've heard that this can cause a check engine light but it doesn't seem to always do so. I don't know how much gas will fit there, but it might be 1 to 2 gallons. Even if you don't get a check engine light, it can't be good for the emission control systems to do this.

When you get to 300 miles, if the meter still hasn't moved, go fill up again. If it takes more than 3 gallons, the meter probably was jammed. If it stays jammed, you get to decide whether you want to shell out big bucks to get it replaced or live with filling up every 300 miles, not knowing how much gas you have.

I'd like to remind you of the Toyota advertising for the 2004+ Prius:
"Driving a Prius 24,000 miles produces fewer smog-forming emissions than spilling 1 cup of unleaded gasoline."


Topping off a gas tank is a bad idea in any car.

It's far too easy when topping off to get fuel into the vapor recovery
lines, poisoning their effectiveness and causing the fuel to escape as
opposed to the cleaner option of burning it.

Often the extra fuel from topping off is just stuck in the pump's
vapor recovery, to spill on you or the next customer, leading to another
emissions problem and you also overpaying for unused fuel.

Rounding up to the next $0.25 might not hurt, but I always just stop
at the automatic fuel cutoff to be safe.

OK here's the update, going to work this morning, at 211 miles, the first bar goes out :D obvously I filled this puppy to the max. Thanks for the replies everyone and for the links mrv. I got into the habit of toping off a couple of cars ago when I had one that shut the pump off as soon as it got to about 1/4 full no matter how slow you set the delivery, so it was either keep clicking the pump or have to gas up every 50 miles or so. But I have now learned my lesson!

I forgot to burp the baby when I added an extra gallon from clickoff as I usually do. Pump had run really slow and had let me put in a gallon without stop. Sure enough, when I went to check the level, BELCH!.

I was able to put the nozzle back in, and slowly purge the air out of the tank.

Got to remember, every 1/10 to 1/4 gallon after clickoff, burp the baby! (pull out the nozzle, then put it back in).

Or just use full serve.
Sanny, "full serve" so you can keep your beautiful smelling hand forever !
Well, actually... self serve is illegal in NJ. And our gas prices are lower than yours. Go figure! :) And yes, my hands are fresh and clean!

I'm relieved. I thought someone might have threatened to relieve you of your hand!
