As far as maintenance and repairs goes, mechanics usually take a few rags, clean up the oil and throw the rags away. Thickness is irrelevant.

It's a function of the diameter of the tank, which is unknown.

Not enough information in the question. Temperature of the water? It affects the density. Density of the oil?
