Why does gasoline eventually go bad?
In: 221
Gasoline is a complicated mixture: ~150 different hydrocarbons, including butane, pentane, isopentane and the BTEX compounds (benzene, ethylbenzene, toluene, and xylenes), plus lubricants, anti-rust agents and anti-icing agents.
As with most solvents and combustibles, gasoline off-gasses really easily, even at very low temperatures (which kinds is what makes it a good ‘Pushahol’.)
The problem is not all of these components evaporate at the same rate (or at all).
So, eventually, more of the volatiles evaporate off and leaves you with heavier concentrations of non-volatiles.
After enough time, you are left with gunk.
Things fall apart. The center cannot hold. Screws fall out all the time. The world is an imperfect place.
Mostly it’s about the light components evaporating in the short term. In the long term the type of compounds called olefins react together to form gums which plug small holes in the carburetor.

If it’s got ethanol in it, the ethanol becomes a jellied substance over time. Not as big a deal in larger, fuel injected engines. However, for small engines such as lawn mowers and other handheld, it blocks up and corroded the fuel lines, carburetors, and even intake valves, keeping those local small engine repair shops in business 😅🤣🤣
