"but, if the need arose, I could (although I'd probably brew and distil alcohol instead of refine petrol, petrol isn't great, even with ice and a slice)"
You have to distill the octane from the crude oil before you refine it, which involves getting rid of as much octane (and replacing it with such catchily titled compounds as (2,2,3)-trimethylpentane, although (2,3,3)-trimethylpentane will burn better). I'm saying you can't do either yourself.
Did you make the device you typed your comment on yourself?
