"Close enough for government work..."And um.. *ahem* this 2020 Ford Ranger 2WD (fueleconomy.gov)
usually you have around 2 gallons left when the gas light comes on in
Just to point out, the citations in that "thermal expansion characteristics of gasoline" are from 1926.actually those pumps are calibrated before being inspected and sealed by the county or state.
We had a 5 gallon can that was tapered at the top with a glass bubble that showed you exactly how much was in the can. After pumps were repaired or replaced we needed t re-calibrate the readout so it would dispense more then 4.5 gal (90%) but less than 5 gallons (100%) so we were within the 10% range. this was to compensate for the thermal expansion characteristics of gasoline.
we were buying fuel at 95deg F from the refinery, but when transfered to underground tank it would cool to about 58deg F and the fuel would condense and he would loose volume.
Interesting correlation:It comes on when you have 50 miles left at whatever fuel economy you've been averaging over a given time/distance. It's not about a volume, it's a distance.
When I tow, it comes on at a quarter tank because I'm getting 11mpg. It comes on at an 1/8th when I'm driving normally without a trailer.
But always it comes on when it says I have 50 miles to empty.
So even if you were just about in the middle of that stretch, you'd likely make it to (or back to) a gas station!What is the longest stretch of road without gas station?
Interstate 70 in eastern Utah. Between the towns of Green River in the east to Salina in the west lies a 105-mile stretch of highway with no towns, and only six exits. There are no gas stations, making this the longest stretch of service-less interstate in the country.
Rated capacity is 18.8 gallons. Your pump shows 19.5, which is 0.62 gallons over. I doubt that the filler neck would hold 2+quarts, and that would also have meant that you ran the tank absolutely empty, which I believe would be impossible.Might be time to call weights and measures to report the station, or
maybe the fuel is going straight into your oil. ?
Wonder how much the filler tube holds?
ok, 71.2L capacity divided by... aw, you do the math...80 liters of diesel. ?
