    Is over filling oil bad?

    I just changed the oil. Put in about 4 1/2qts and when I went to check it today after driving around doin a little shopping the stick was reading low. Then I put some more oil in it and now it's way over the full line. What do i do now and did I damage anything. The car was running fine so I haven't noticed any change. Please help a noob out.

    It can be. If the crankshaft is splashing around in the oil, the oil will foam and you could get air in the oiling system, which is never a good thing.

    You should always wait a few minutes after you shut the engine off so the oil will drain back into the pan so you don't get those false readings.
    My water heater has a blow off valve.

    Too much oil can also blow seals, not a good time.
