I just filled up gas in my prius and it generally maxes at 9 gallons but this time it went to 11.755 gallons with 1 tick left on meter. Is the station flawed? This has never happened before.
So you think the station's computer is cheating you or what? I imagine you're a long time Prius chat member maybe and you feel your car up just like the people here talk about fill it up until it burps hang up the pump You got about 8.8 9.1 gallons maybe on a good day. That's wonderful but that's not what I do I feel that sucker up until it burps and almost kicks back at me and after it stops subsides.I continue to fill up the tank squirt squirt squirt until I go from the 8.8 to 9.1 I will get 10 gallons in that car maybe 10.3 that was with a blip showing not flashing yet It is not recommended to fill these cars up like that because people say so I've been doing it the life of the car since I've had it I believe this keeps my bladder stretched expanded and then the minute it goes down and gets to empty I immediately fill it up I don't leave it sitting empty overnight or for the day or for two weeks because I'm going to be riding my bicycle no sir I stretched that bladder out like a pregnant woman's tummy immediately Don't ever let it stay subsided and flat It's like emptying your well tank the blue thing out in your property if you live in the country and leaving it empty for 5 years and then coming to fill it up and wondering why the bladder broke exactly I don't think the station is ripping you off It's too complicated now when we used to do that to people at high value gasoline company that was way back in the early '80s when everything was manual no electronic anything the Veeder root system was easy to manipulate. Not today
Waiting until the last "tick" on the gauge is a dangerous thing to do........unless you like walking when you run out. You won't know the answer until you fill up again a time or two. Gas gauges are notoriously inaccurate. So are the automatic pump shutoffs. Sometimes the pumps won't shut off on their own AT ALL. You might have been on the verge of that "disaster".
Obviously you got less gas than what the pump metering device shows. In other parts of the world this is usually a cheating gas station owner behind it but here in the States where gas is cheap I would give the benefit of the doubt and assume it is just a broken inaccurate pump.
That is not obvious at all. The pumps are checked for accuracy at least once a year by a State agency.
