I think it's more important to put some oil into the new oil filter so your oil pump doesn't run dry (cavitation prevention). Oh, and make sure you install the filter and pan plug before you poor in that thoroughly mixed oil...
Now why on Earth would the pump be any drier after an oil change than it would have after any other normal period of inactivity?
