Why is this still really going on? Oil sits in the bottom of the pan anyways and the pump tube/oil strainer is damn close to the bottom of the pan. A half quart of oil won't make a bit of difference. Make sure there is oil on the stick and forget it. Good lord.
And I change my oil every 3K...with Full Synthetic. Oil WILL last a good while, additives in the oil don't. I'll do mine every 3K. Thanks.
