Corrected entry: We see Chris distill a drop of fuel, and he states that after 20 years of searching he finally has enough fuel. Later on, Wikus opens the fuel cell and is sprayed with a good amount of fuel. Though Chris knows that the fuel is responsible for changing Wikus into a prawn, Chris doesn't mention once that he'll now need to get more.

Correction: We do not know that what sprayed Wikus is in fact the fuel. It makes no sense that the fuel itself would make that kind of change (DNA restructuring). It is entirely possible that was just a defense mechanism to protect the small amount collected.
