and why does this happen?

What everyone else said: Gasoline has a lower freezing point, by a lot. About 75C lower.
What no one else answered: Why? Because water is polar - there is a positve and negative electrical charge on different parts of the moecule. This means there is more force pulling them to each other and into a solid crystal. Enough attracting force to do that at a much higher temperature (32F, 0C).
Whereas gasoline is non-polar and without positive and negative elecctrical charges attracting each other, the much smaller forces between the hydrogen atoms doesn't overcame thermal energy until -75C or so. It is actually a range of FPs starting at -75C when the first compounds freeze out of solution. As it gets even colder, more of it freezes.

Gasoline has a lower freezing point, water freezes at 0 degrees celsius (32 degrees farenheit) and gas has a much lower freezing point, this is why our cars can run in frigid temperatures, along with the combustion of the gas

Freezing point (FP) of pure water= 0 deg C
FP gasoline/ petrol= minus 80 deg C app
Definitely, gasoline has a much lower freezing point.
Even in terrains like Siachen, India- the highest and coldest battle front- temperatures hover around minus 50 degC- all water is frozen- even it's difficult to pee as it freezes before it falls- liquid gasoline generators and engines are used.

Gas, water freezes at 32 F or 0 C.

Definitely gasoline. Water freezes at 32F. Not even a cold winter day. But gas, you can pump gas when it's supercold outside.

water freezes at 0 degrees while gas or petrol freezes at about 20-30. degrees less that why cars and planes can work in really cold temperatures -all liquids have diff meltin and boiling points -hope this help !

That's kind of obvious. You don't see your gas tank freezing solid every winter.

the only element that i'm able to upload to fci answer is that I appeared up countless oils, diesel fuels, etc in a handbook and none of them confirmed an excellent temperature. often hydrocarbons only get extra viscous as they get less warm. and that i recommend less warm like in -3 hundred to -4 hundred stages. Wasn't it on Jupiters moon that they think of that there are lakes of liquid methane CH4? they might seem good yet will creep and pass. i be attentive to from experience that in case you're taking forty weight motor oil and get it to -forty F this is going to string like honey and make little dots like chocolate chips with tops.

Gasoline. It will burn at -97F
