Yeah, I agree, but I don’t have one .. and because I drive a lot (thus think a lot, when not listening to Wilkow .. etc.), I wondered about might be involved.
You have to learn to filter the oil of particles, as you cannot just pour it from the pan to the tank.
Creating gasoline is a distillation process. It’s not a process that you can easily do from home as the amount that an average person can create on his own would be very small.
Not to mention that it is also dangerous. Each gallon of gasoline, when pressurized is the equivalent of about 15 sticks of dynamite. You could easily, if you make a mistake, destroy the area that you are working it when trying to distill gasoline.
You’re far better off to store diesel in large storage tanks as diesel can keep for years, as I understand it. Whereas gasoline is really only good for a couple of months before it degrades to the point of uselessness for running vehicles.
