Astute observation. Gasoline isnt made to a recipe. Its a soup of different crap that changes by the hour. The art of refining is making money off every drop of oil you refine. In other words you blend the good with the bad in order to meet min specs.

of course it is corporations are starving, dont cha know.. lol

Theres kind of a catch with that question:

Id speculate on average 175-200* F

Gas is a swill of way too many chemicals/petroleum distillates to list and many of them boil pretty low like Ethanol 170-ish F* There are others in there that flash under 100* F but they are pretty low percentage of the whole in a 10gal tank of gas.

Old gas tractors that are carbed can pull vacuum into the tank through the fuel line if there is an extreme difference. Hot gas tank and suddenly parked in the shade or winter. Those old tank caps were not the diaphragm type now used. Often they were just a metal cap with a paper/wax seal and tiny hole punched in the top. Over time they can turn into a sort of check valve in the right temp environment. My grandfathers old Gravely did this if he stopped for lunch after cutting grass for a few hours. He drive it to the house and park it in the shade and by the time he came back out the glass bowl would have a bubble in it.

Is there a spec for boiling point? I can see where that fuel tank might get upwards of 180 degrees on a hot day. The coolant is 180 plus and fan blows air back toward the tank under a sheet metal hood.

Yes there is along with Reid Vapor pressure.

Refining isnt a high profit margin business. It also requires an immense amount of capital. This Iran war thing has made us money but the previous quarter results which were released today had us over 100 million in the hole.

The clear 91 octane there costs much less than here. Currently It’s $4.999 per gallon with the state’s 32.9 cents and federal 18.4 cents tax.
