It was original, then I changed it twice once I started noticing the smell, it died 1K miles after my two changed, I guess they did not save it, distraction was already in action.
Now, my theory is excessive idling time. I purchased the car from private party and he would have car idle all the time, allot, every time I come see the car, he had it just idling as he parks. But thats just my thoughts, also it is possible that they maybe under filled by the factory, because first change I was able to only get 12oz out of it, it's ether got overheated and evaporated or under filled.
But anyway, ford should have the drain plug on ALL OF THEM and add that to maintenance schedule every 25K miles, problem solved...
