Just some general info for you guys that have not changed the oil yet on your new Challenger. All bolts are metric so FYI. The ground effects plastic plate has 4-10MM bolts and it slides out from underneath the front air dam once unbolted. The oil pan drain plug is a 13MM bolt and was on fairly tight from the factory. Note the green factory markings. The oil filter was almost welded on from the factory and I broke my filter tool trying to remove it.
Had to drive all over town to get a replacement. The oil after 1000 miles seemed fairly dirty which surprised me. Added 7-qts of Mobil 1 0W-40 and a new Mobil 1 oil filter. The Challenger is happy now
