Does anyone else notice this "problem?" Everytime I get gas I reset my Fuel usage to zero on the dash. This is where the gallons consumed register. I stop at different stations in my travels. Some stations show more fuel pumped then the counter in the cars shows. It is NEVER less.

The stations I go to near home are always right on the mark even to the tenth and this is why I go to them. How can this be?

My conclusions, not only are gas prices out of sight they also are cheating us on a 1/2 here and there.

Once when the difference was over a gallon I called the listed county auditor to complain. His response was it may be possible they were registering wrong, we can only check them so often. When I asked yea but why always over? He said well you know the answer there.

So if you don't check it out, BTW I stop my fill up when the pump shuts off, round up the pennies so the fill ups s/b consistent or at least closer then 1/2 a gallon or more.

I reset fuel used when I refill, and every time I top off or refill, more than what was used goes in (according to the pump).

So either the computer in the car is lying to me, trying to not alarm me as to how much fuel is consumed, or the pumps as you mention.

When I startup I smell a little fuel (or exhaust), and that's the only time I smell it. I've checked the lines and they seem fine, the rail is fine too (no recall on mine, and I looked at it too). The only thing I have not checked is the canister and lines for the gases. The smell is only at startup, when the injectors get a good spray though.

i've noticed this also not as much ever goes back in as the car says i've used. it's a damn conspiracy. and i HOPE that inquiry into the gas company profits last quarter REALLY happens.
Maybe you missed this yesterday:

http://www.cnn.com/money/2005/11/09/news/economy/oil_hearing/index.htm?cnn=yes

Don't expect anything to happen out of this... This is pure showmanship and nothing more. If they didn't make a show if it, people would be furious, but the Congress knows it is powerless to do anything about this. Maybe that's a good thing. I don't know that I want the government meddling in that kind of area anyway. "You can't make xx amount of profit or you face yy penalty." That's more absurd than their profits, and that's why it will never work. Here's a better alternative: Use less fuel! Less fuel consumption = lower gas company profits. I fail to see why the government needs to fix this perception problem. By the way, what exactly was their profit as a percentage of total income? How much did their expenditures change from one quarter to the next? What was their profit margin before the crises after adjustments for expenditures?

It's not the profits that need to be fixed. It's the price gouging that led to them, IMHO.

Mike regarding the profit margin they claim it is around 7%. Not sure if that is higher or lower then past years. One thing is for certain if your revenues go up 50% ($2 a gallon vrs $3) and the costs are relatively the same or not proportionate, yes profits go up 50% also. It should be no surprise they are making record profits, the price is at record levels.

And you are right, few of us are doing much to counter this. We shake our heads and fill up. Personally I looked at higher mileage cars, even the Prius and it's not for me.

I don't think the computers lying, as I mentioned at the stations I trust I am always right on. Funny isn't it? What a racket.

The car has no reason to trick any of us. In fact, I'd think GM would go out of its way to ensure accuracy here. I'd bet this is a simple case of mis-calibrated fuel filling pumps. Here in Ohio the counties watch this stuff like hawks. Every now and then, they still find some quicky-mart trying to rip people off. Sometimes it's about a 10% miscalculation.

If you suspect a specific station of shorting you on gas, I'd contact whatever organization is responsible for measurement. Generally, there is a sticker on the pump stating when it was last measured and what/who the regulating agency is.

"Rob" wrote a very long post concerning this same issue pertaining to the Cadillac computer data for fuel level, fuel consumption, etcetera. The bottom line is the values you see are a result of some very complicated mathmatical computations factoring many variables. What you see on the DIC is not just some arithmetic using tank level information and miles driven. The Cadillac computer data is very likely more accurate than the pump.
