Common mistakes

Corrected entry: It's very common for shows, games, or movies that take place after the end of the world to still show people using fossil fuels like gasoline and diesel in vehicles. However, with the production of gas having ended, this could not last very long. Even when properly stored, civilian gas supplies would go bad and be unusable after about a year, diesel a little longer but not by much. Private stashes of gas, like in cans, would only last about 5 months. And the military supplies of gas would, at best, last for 5 years.

Correction: Stored gasoline is typically treated with fuel stabilizer (about 2 ounces of stabilizer will treat 5 gallons of gasoline and prolong its shelf-life by years). All of my stored gasoline is treated with stabilizer, and I've used cans that are 5 years old and older. Even untreated gasoline can have a remarkably long shelf-life: Some years ago, I sold an old Volvo that had been sitting in my garage with a dead battery for 11 years; the buyer brought a fresh battery and installed it just to test the starter, to see if the engine was frozen. To everyone's amazement, the old car immediately started, revved and purred like a kitten, burning the gasoline in its tank from over a decade earlier.

Correction: This all highly depends on the quality of the gasoline and the amount of ethanol and its exposure to oxygen. I've heard about jerrycans of gasoline 25 years old still usable. It's also possible to purify the gasoline again so it's usable by filtering it. Don't need a huge refinery for small amounts.

But then again, the common person or every day man wouldn't know how to do these things. Use of gas after the apocalypse is too common in films.

Usually plenty of people around to figure it out. On a small scale at least.
