The Olds oil fill tube dumps into the front section of the pan. The dipstick is in the rear main pan. When operated the engine crank and rod caps throw most of the oil from the front to the main rear section. While changing my oil I did a small experiment. With drain plug out after a few minutes the stream had diminished to separate drips, usually the point in time where the plug gets reinstated. I added some fresh oil to the fill and drips continued to slow. Another pour. Waited. Nothing. Added more fresh oil. No increase in drip speed. 3rd time and still nothing. On forth try the drip speed started to pick up so installed plug as fresh oil started to come out.
Conclusions-- The add-on front pan drain is not needed (not much yield is the consensus)
And you must run the engine after each oil add before checking stick. I did not keep track of the amount of oil added before it went over the waterfall to the rear pan, but estimate is 3 cups. Will document next time.
