I would not do anything to the container. If oil wont leak through it, then something thicker like water certainly wont. The oil containering company
has a lot at risk in the way of liabilities if it leaks. I Think they know what they are doing. In screwing (pun intended) with their design, you may in fact actually introduce a problem.
Just use the container for what is was designed to do - keep one liquid and another liquid out.
