Oil Change---2 quarts vs. 1.75---8 ounces more than spec---does it matter?

    Just changed oil in the Turf Tiger.

    Manual calls out 1.75 quarts.

    I put in 2 quarts each change.

    Use Amsoil 4-Stroke, 10W30.

    The difference is about 12.5% more oil. Does it matter if there is a little more oil in the crankcase?

    It matters to the head gasket over time.

    Head gasket? How would an overfill affect that?

    I could believe seals in the lower end could be stressed, but a head gasket?
