Hey guys, My wife picked up a new JKU and the dealer wasnt sure when to do the 1st oil change, I see some guys here do it at 800 miles or 1000 miles???? Is this true? The dealer looked at us like we were crazy when I told him that.. We have about 3000 miles on it now.. Can someone let me know what is the correct miles to do the oil changes.. I wont be using synthetic .. Thanks Guys!
