To be honest, I can't say changing the oil will do anything other than remove the contaminated oil that is presently in the vehicle. Make sure the filter is replaced too.
If you see metal shavings in the oil, that really isn't good news. But I have a couple questions. First, do you hear any knocking or ticking from the engine? If not, has the pressure been tested using a mechanical oil pressure gauge?
