60 liters in canuck = 15.850323 gallons in US. 57 liters in canuck = 15.057807 gallons in US. Given that the Japanese talk canuck, I think the conversion was to, rather than from US speak.

I went 56 miles once with the empty light on. I was in some wodded area in PA and I had NO IDEA where I was and the closest gas station was 50+ miles away. After I got to the station, I found out that I had about a gallon of gas left in the tank before I filled up. So either the gas light came on too early or Exxon's 93 octane gas from Phillipsburg, NJ is magic gas. You decide.

The tank volume may be less than spec. My tank held 0.8 gallons less than spec on a fill up after running out of gas. Prior to that incident, I too had thought I could have driven further based on what I thought was left in the tank assuming the spec capacity.

Or maybe, just maybe, the pump at the station you went to was incorrectly calibrated?
Should I assume there is a large variance of almost a full gallon in a mass produced part or on a single gas pump as to which I know for a fact can be maunally calibrated as often as a service station should choose (or not choose)?

well i can verify that when i went to go by everclear from arizona to california, i know that about 20 miles outside of the california arizona border, my light came on after haulin *** on the way to parker, then from there light came on but able to make it to parker n thats 20-30 miles on the arizona side, but then again i slowed it to 45 mph in 6th gear n made it with the light on and with hopes n dreams to a shell gas station where they wash ur windshield for ya too lol.....but yea i would say depends on ur speed n what gear i gota about 50-60 miles.

Hmm if it was in fact on the horizon wouldnt the information simply appear frozen? I mean theoretically you would never really see it fall in...as it approached the horizon it would appear to stretch and warp until it would look like it froze and then vanished...maybe the hawking radiation emitted would produce a legible post...

Mac11 (Sorry, I don't know how to insert that fancy "Originally quoted by....." :
You speak true about the unlikelihood of a mass produced part varying by much, and that a particular gas pump may not read correctly. However consider the following.
We are talking about a 5% uncertainty in a fluid volume. Most drivers and auto manufacturers would expect this to be quite acceptable. I don't think the RX-8 was built around the tank. The tank was built to fit the available space and it came out to be approximately 60 liters. It will be mass produced with high accuracy at whatever the volume is, but companies take liberties with accepted uncertainties. Speedometer readings are usually a few percent higher than true and there is the horsepower issue.
You can get yourself into some real trouble (such as krock1030 almost did) if you believe that you have more gas in your tank than you really do based on past fill-ups. That 5% error rapidly escalates to a 500% error if you think you have a gallon left when in fact you only have 0.2 gal.
For interest sake, let's look at thermal expansion. The coefficient of volume expansion for steel is about 0.0036%/C, for gasoline it is about 0.095%/C (http://www.ac.wwu.edu/~vawter/Physic...hermExpan.html ). Let's say that the temperature difference between the coldest day in Alaska and the hottest day in the Sahara desert is 100C. Then a steel gas tank would expand by less than 0.4% in volume while the gasoline would expand by almost 10%. It's pretty safe to say that for less extreme temperature variations, tank volume changes are negligible, but people in different parts of the world could report 5% differences in the volume or a given mass of gas.
So I may have gotten 60 liters of gas and only paid for 57, but the day was clear and I didn't see any pigs flying. I don't know how gas pumps adjust to temperature changes, but I do recall seeing notes on the pumps indicating that flows were adjusted to correspond to certain temperatures. However I don't know how that would translate into the volumes I pumped that day.
And maybe the tank is 60 liters but you can't get access to all of the gas. But until someone else provides more accurate information, my money is on the tank volume being less than specified. Based on the gas milage I get, I have frequently been surprised at how much gas is supposedly left in the tank on a fill-up. Others have had similar experiences and an earlier post made reference to 'magic gas'.

good movie
I am not saying the gas is expanding due to any weather related anything. I'm saying the pump is just reading off. It happens a lot more often than people think.
pull your gas tank out of the car and find out. then go back to the gas station and call the standards comission and find out.

That post simply lost information.
Or, maybe it never had any...

Yeah I read the title of a paper about a theory which was supposed to replace the theory of hawking radiation...just never got around to reading it yet...got distracted with Heim Quantum Theory at the moment...unfortunately I haven't had free time to finish reading that paper either so I completely comprehend it...usually takes a few re-reads and then math before I can visualize it...
I'm simply desperate to get off this rock...and AAIA2004-3700 looks like the best...albeit fringe chance...

My wife did this once about 1 mile from our house coming back from a trip. I already beat her once, but depending on the answer I get she may be in for another round
No, i'm kidding....but really
