Slight oil overfill

Hi,

I think I am probably ok, but I overfilled my 2007 Trailblazer past the full mark on the dipstick.  It is only 3mm past the full mark.  Is this okay?  Mileage is 90K with a 4.2L inline six cylinder.

It's fine.

Try to drain the excess out...maybe keep wiping the dipstick until the level drops lol. You don't want to overfill on oil because it will actually hinder lubrication from the oil becoming a frothy-like consistency from making significant contact with the crankshaft, and that frothy oil will not be able to get siphoned up by the oil pump.
