[Mad Max] If gas is so scarce then what powers everyone's cars?

Title is as it says really, I noticed in re-watching the newer Mad Max film it says something along the lines of all the gas running out... so if it's so sparce then what powers everyone's cars?

It's running out in a sense like energy crisis and ordinary people can't afford to buy any meaningful amount of it.  It becomes a resource similar to radioactive material today, highly controlled and hoarded.  Same thing with water and bullets that's why three of the 'towns' regularly trade with each other.
