Sounds like a marketing gimmick.

I doubt if anything bad is really going to happen as a consequence of skipping the "flushing oil"... unless the mechanic gets wise on you and puts something into the engine behind your back.

Besides, if anything bad did happen to the engine within the given time period, I doubt they would actually shoulder the repair expense, instead of simply offering an oil change service free of charge for both labor and materials.
