Okay so here is a good question, how long has everyone been running +1 quart? Or 6 quarts total? Months, years? Any one that can disprove the theory of long term effects by over filling? As many have said, the stock oil pan is deep enough, however, it's always nice to hear from experience.

I run either 6qts or 7 qts but thats because i have the oil filter relocation, and an oil cooler. I've had no problem what so ever...
and i do corner hard and drive fast, so i want that insurance when i do so.

Why don't you prove that running 4 quarts is better than 6?
The owners manual in later years calls for 5 quarts with a filter. That is called an update, and usually acompanied by a Technical Service Bulletin(TSB), which the manufacturers deliver to the dealers.
One the worst automotive myths ever is that it is better to run the engine a little lower on oil that a little over. Somebody probaly put a few gallons of oil in something, watched it run out, and ran with it from there.

all cars are different. Some can stand to have extra oil in it and some arent very tolerant of more oil. The owners manual in every car i have seen has said to put the oil somewhere between the low and the full mark, doesnt have to be on full, let alone over. Many on here say its fine to fill over because of the size of the pan, saying there is proof, i kind of take their word on it as i havent actually seen any proof, if there are pics with measurements and such id love to see them.
Yes, the oil goes between the two marks. I endorse owners manuals, but recognize they are made for the masses.
I don't think being a bit over the full mark matters at all. As soon as you start the car, the level in the pan drops to fill the system anyway.
These day I run 6. It's actually 5 because my bypass filter sucks up one quart. With it like that the level is on the full mark with the engine freshly shut off and where the wire begins when it's cold. That said I ran exactly what the owner's manual states (4.2 quarts) for 17 years and never had a problem.
I run 6 qts. as well. The filter should hold the extra qt. once the motor is running.
On some motors this can be a bad thing, as the crank will hit the oil, and aerate it, or cause tiny air bubbles(you'll see it on the dip stick). This can be kinda hard on the motor, if the oil is getting pumped that way. That is what the "myth" about running a little under the full mark is about. This becomes very apparent with long stroke motors and shallow oil pans.
