Since our car requires aprox. 5.5 quarts of oil, we need to buy 6 quarts of oil per oil change. So what do you guy's do with the unused and open .5 quart of oil? I heard oil can go "rancid", especially after the factory packaging has been opened. Is this an old wives tale or truth behind this, and does this only apply to standard oil or to synthetic as well?
