engine oil for 4.6 l v8 gt
 

will 1/2 quart extra hurt this engine? some clowns at the lube shop overfilled it.I hear this happens quite often with these places.You would think they would know better.I guess I better start doing it myself. How much overfilling do you think it would take b/4 it actually hurt the engine? Thanks for the help.

Probably will just make the engine burn the extra 1/2 qt. Might foul the plugs slightly, but won't really hurt the engine much. What's the crank case capacity?

6 quarts is the capacity

I'd drain and refill..I once put 11 quarts in my 96 GT (dont ask why, how or any other obvious questions to such a retarded move) and after I covered the neighborhood in oil smoke the engine never idled properly again, even after a tune-up. The capacity obviously was also 6 quarts. If you turn the car on and have idle surges and a sputtering exhaust sound you may wanna empty and refill.
