Just saying viscosity is important, and the Widman Viscosity Calculator gives some insight into how much gasoline is mixing in the oil.
Again, I mentioned the Widman earlier.

You can put in the kv100 of the new oil, then put in the kv100 of gasoline, and mix them until it equals the current used-oil kv100, indicating how much gasoline might be mixed in. This may be thrown off if there are more than 6,000 miles, since oxidation will increase viscosity after about that point.
Its a rough measure of how much fuel might be present, but you also have to take into account an expected loss from VII permanent shear.
One can play with the numbers to get some idea, but nothing too accurate.
