If the oil is only a touch over the full mark it wont make any difference. But if its way up on the stick, drain it and put the proper amount in there. 5.3 qts according to Mitchell. Even 6 is ok if its not over the full mark. Put the 5.3 in crank it and then check it. You don't have to change the filter if you done it recently, within a couple thousand miles.
