Some of them provide a table with specific base oils in the rows and percentages of each base oil are in the table, along with the percentage of additive package and the motor oils' viscosity. This is not in the upper parts of the patent where large windows of various components are mentioned. That's the loosey-goose part.

Take any motor oil patent or any chemistry patent and try to nail down the exact formulation. You may get 10 or more different formulae described and within each formulation the components may vary as much as +, - 50% or more; and the reason is give the patent as much coverage as possible.
