How far can I drive with too much oil

My wife's car gave the 5% oil life sign. I thought that this meant that it only had 5% of the needed oil in it, so I added two quarts. I realize that this was dumb.

I am now significantly over the oil line. As it turns out, I have an appointment at the dealership tomorrow, and the dealer is 25 miles from where I live. Am I safe driving the car the 25 miles, or should I drain some of the oil? Let's assume I am about a full quarter over what I should be (the two quarts added, less the oil used in 7,000 miles of driving).

Thanks.

    I would drain it out. Too much oil can cause cavitation (foaming) meaning less lubrication for the engine. It can also create too much crankcase pressure and cause seal leaks. Two quarts over is too much. Maybe 1/2 quart would be ok. If you buy a suction device at the auto parts store, which draws oil out of the dipstick tube, this is a lot less messy.
