It would be better, and I have heard of poeple doing this, to change oil and then run it for an hour or two and drain it. Then refill and go. This helps to "wash out the residual oil in the HPOP and system.
I have heard of this helping with cold starts but with oil as high as it is I won't be wasting it. LOL
I have 270,000 miles on all eight stock injectors. Starts fine still.

i agree, even he said, you ever wonder why the oil gets black right when you start the engine after a oil change that right there is enough said the oil is always circulating you do not need to change top oil it is just a waste of time.but i must say my oil always stays clean because i change it often.i never get black oil.
