If you subscribe to the theory that all crude comes from organic matter that is crushed, heated and puterified for a long time, don’t you wonder if there are ancient micro-organisms lurking in it?
When you take a crude sample offshore, don’t you worry that the mist that comes of the collection container hasn’t seen the light of day for millions of years, and the last time it did it was a living organism?
Petrol, not too worried, it’s gone through a distillation tower, the heat should kill off those little critters.
Makes you want to wear a mask all the time, don’t it?

And…. they get the parrafins from the crude and spray it as coating on apples and oranges (try scraping the apple with a knife and u can see the wax come off)
anyway, it looks like a new comic hero – Crudeoilman is born (after prolong exposure to crude oil). his power are – convert water to crude oil. and the government ties him to a subterranean chamber and make him covert water to crude until he dies…
that’s the crappiest comic story line….
sorry, just rambling…
