My recently-acquired 2011 Mercury Grand Marquis is nearing it's first oil change under my watch. Car has 178,592. It was done by the previous owner about 3800 miles ago. Under the cam covers appears nice and clean and it hasn't used any oil that I can tell since I've owned it.
So. My choices are 5W-20, 5W-20HM, and 5W-30. Asking for the collective's opinion.
