Which was my point, but The Spectacle claimed it was due to inaccurate gas pumps which is most definitely not the case.
By the way, I no longer fill up as much as I used to, one or two clicks at the most now. I've read that overfilling the tank can damage the charcoal cannister that is part of the venting system, so it was a bad habit I broke myself of...I've heard a replacement costs $400 on some cars! Cheers! M2 |

What's so funny? Maybe "inaccurate" was a wrong term...perhaps miscalibrated is a better term. This could also be affected by the time of day you're filling up.
I've put "more gas than the manufacturer specified" in every car I've owned, most of the time by a considerable amount. I hardly doubt its because of non counted space from the tank to the fuel inlet. But you guys go ahead and think what you want. |

The chances of a "miscalibration" as you like to term it are about as remote as the pump being "inaccurate." If you read my above post you will realize that every state has a program that strictly monitors these things and there is no basis to your claim. But you are correct about the properties of gasoline changing during the day (well, depending on the temperature), but it isn't enough to make that much of a significant difference (10%+). The truth is that typically the owner's manual provides a reasonable estimate of your vehicle's fuel tank capacity. Some manufacturers estimate that the capacity of a fuel tank may vary by as much as 3% from the actual tank capacity. This results from normal variations in design characteristics, the manufacturing process, and other inherent factors. The rating is determined by taking an average volume based upon the capacities of multiple tanks. Furthermore, the rated capacity may include only the usable portion of the fuel tank or it may include both the usable and unusable portions. The unusable volume is the portion of the fuel tank's liquid capacity that lies at the bottom of the tank out of reach of the fuel pump. The usable volume is the portion that can be delivered through the filler pipe into the tank when the vehicle is level. The vehicle's fuel tank capacity does not include the volume of the filler pipe or the vapor headspace, which is the portion of the tank compartment at a level above the filler pipe neck. Sometimes people attempt to deliver additional fuel after the gas pump automatically shuts off, commonly known as "topping off". When this happens, the additional fuel begins to fill the vapor headspace and the filler pipe, which are not considered part of the tank's rated capacity. This may result in a receiving more fuel than the rated capacity in the owner's manual. This may also occur if the lanes that surround the gas pumps are not level and some of the fuel shifts into the vapor headspace, thus delivering more fuel into the tank. When the fuel tank indicates a certain level, consumers often assume that this indication represents a corresponding fraction of fuel tank capacity. For instance, if you have a fuel tank rated at 18 gallons and the fuel gauge indicates that you have half a tank of gas, you might assume that you have 9 gallons of fuel remaining in the tank. If you then fill-up the tank and receive more than 9 gallons you would assume you now have more than 18-gallons in the tank and would conclude that the gas pump is in error. Besides the fact that the rated capacity is only an estimate, many variables can affect a vehicle's fuel level indication. A shift in the fuel level may occur when the vehicle is not on level ground such as when on a hill or traveling around a curve. This temporary change in the position of fuel within the tank can cause the fuel gauge to indicate more or less fuel than is actually in the tank. The indication of fuel in the tank can even vary depending upon the position of the driver's eye when reading the gauge on the instrument panel. Many vehicles today have trip computers and mechanisms for estimating mileage to assist the driver in planning travel based upon the fuel that remains in the tank. The vehicle's mileage for each gallon of fuel depends upon a number of conditions such as maintenance, cargo and passenger load, use of accessories such as air conditioning, driving habits, terrain, traffic, weather, and even fuel composition. When these factors require the engine to work harder, fuel consumption increases. Trip computers may calculate the estimated miles that can be traveled on the remaining fuel based upon the vehicle's fuel economy during a specific driving period. The estimated miles may vary greatly depending upon these external conditions. And no, I didn't just type all that, nor do I just make shit up, it came from here. Or you can read this article. Or if you want all the info you'll ever need and are lazy to look for it, just click here. Either way, as the cavemen used to say in the old Geico commercial, do a little research next time...

And to support my claim. In NJ we are not allowed to fill our own tanks. Our attendants will usually stop filling as soon as the auto thingy clicks it off. Then I will only get about 65-70mi on my first bar. When I go to PA for gas I'll try to squeeze more gas in....resulting in my getting 92 miles on my first bar. After reading what MadMax has written I'll prolly stop doing that.

I'm still amazed and amused by this. New Jersey is the only state that has this law. Don't they realize how stupid it is? In every other state, 95% of gas stations don't even have attendants available unless you're handicapped.

Anyhow, the law in Oregon was supported by a whopping 17 declarations rationalizing the prohibition of “any person other than the owner, operator or employee [of a dispensary where class 1 flammable liquids are dispensed at retail]” from using “pump, hose, pipe or other device for dispensing the liquids into the fuel tank of a motor vehicle or other retail container.” Violating this law will get you slapped with a $500 fine. Of course, way back then most gas stations were full-service...as the first self-service station only opened in California in 1947. Both laws have been challenged in court, and Oregon motorcyclists won a small victory in 2001 when a law was passed allowing them option of fueling their own bikes; but for motorists the law still applies. There is your history lesson--and fun factoids to share with friends--for the day! Cheers! M2 |

In RI, gas stations are required to remove the clips on pumps so you have to hold the handle the entire time. No setting, locking the handle in place and taking care of the windows as you pump the gas. Not a big deal but in the dead of winter it can be annoying having to stand in the wind with your hand on a freezing metal handle.

Madmax I'm not going to lie to you...I didn't read half of that novel you posted. But good on ya' for your "research". If you think that all gas pumps are properly calibrated just because some agency goes around randomly checking pumps, you're a little naive. The world doesn't work that buddy, I don't care how "illegal" it is. Lol...you must get gas at some really "trustworthy" stations. I know most gas station people really don't care if their pumps even give receipts back half the time, let alone calibrate something in the pumps. But again, believe what you want

And with thrashing gas prices, to think that a franchised gas station(who is suffering as much as you are when gas prices sky rocket) won't screw you over is freaking ridiculous. Have you EVER seen someone checking gas pumps in a gov't truck?? I'm with spectacle here guys.. Blind faith in government regulatory committees is ruining the world. |

guys, I have a '04 hatckback 4 dr. 2nz-fe engine. I found on the web it holds 11.8 galons, is it accurate? according to my calculations it should have around 2 galons for reserve, during the las bar blink :S
|
04-14-2009, 08:44 PM | #34 |
I can, and have, put 11.2 gallons in my HB. Course when I fill up, I top it off right up to the cap. In otherwords, I always fill the filler neck tube and I usually wait till the last bar is blinking before getting gas.
