    I always wondered what happened to all the neat reports of cars that ran on old oil or could get 50mpg in the 50s. Guess they were too disruptive. We can’t have nice things. 😮‍💨

      Cars that run on old oil are basically just diesel engines. It’s also pretty easy to get a vehicle with high fuel efficiency, it’s really hard to get one that also meets emission standards and doesn’t kill you in a crash.

      A lot of those claims are just direct horse shit in the “infinite energy” category, or “this car runs on water”
