I am sure you, like myself, are highly skeptical of any change in mileage.

We never decided whether too much oil will cause a rear main seal leak.

another old wives tale?

Yup old wives tale actually the opposite of overfilling is a main cause, as in not enough oil in the motor can cause the rear seal to dry out and then leak if you fill it up again. Or storing it for a long time the seal will dry up and leak or the seal will just get wornout from old age just like any other part in the motor.

Another thing that cause it is an out balance rotating assembly which will wear the seal unevenly causing it to leak

Overfilling it a qt means you can drive it longer without having to put oil in it
