My wife was driving our 2013 Kia Optima EX that we purchased from a friend with 150k miles. There was an oil change sticker in the window that was from less than 1000 miles ago. However we ran out of oil and the engine now has a knock in it and my mechanic said that it's ruined. Apparently, the car burned up all of the oil in 1,000 miles? Is this possible? I was reading on these forums that there was a recall for the 2013 Optima, I called our local Kia dealer and they said there are no recalls for my VIN. Am I just SOL? Any help would be greatly appreciated!
