What happens when you put in too much oil?, The dealership did... Options

[CoolDoctorJ]

When I changed my oil for the first time, I noticed that while the manual says to put in something like 4 quarts, I actually drained about 5 quarts of existing oil. After 3000 miles, could that much extra oil damage something... like, oh, I don't know... the valve seals? I know you guys say the valve seals are a common problem, but it's a problem the car didn't have at the time I bought it, and I've only put about 3000 miles on it since then (most of which was during the time it had too much oil.)

Comments? Questions? Concerns? Donations?

Thanks.

If to much oil is inside of the engine, you could easily blow almost all of your oil seals. Too much oil pressure is really bad for cars. 4 qts for me is perfect, I usually put it between half and full. My friend ( who is a dumb ass and doesn't know anything about cars) put 4 qts too many in his girlfrieds accord. I laughed my ass off, but then my other friend emptied the oil out and changed it. There were almost 8 qts of oil in the thing! How long were you driving it before you noticed that there was too much oil in it? And about synthetic oil, my car runs MUCH smoother with Synthetic. I use fully synthetic Mobile 1, good stuff. Regular oil is fine but if you want more out of your engine use synthetic.
