i was thinking about this the other day. In an end of the world as we know it scenario, gasoline will be gone in short order, so most cars will no longer be able to run. which is great.

However, diesels can be modded to run on other fuels, even used cooking oil. So in theory, if you can get some kind of oil, you can run your diesel. It’s also possible to mod a regular combustion engine to run on ethanol. ethanol is just 100% alcohol. You can make it yourself if you have a still. Albeit, you’d have to have a shitload of grain to get a full tank, you’d still be able to get some fuel every now and then.

All that being said. If civilization as we know it comes to an end, that just means that we won’t be as connected as we are now. but we’ll still be human, we’ll still want to trade goods, services, art and ideas. You’ll need to connect with your neighbors and cooperate to survive. one will grow something, one will grow something else, one will teach, one will heal, one will brew beers. everyone will meet in the square to exchange their goods and knowledge. so, i guess, if you run out of fuel, just get a horse, or borrow the neighbor’s.
