I just drained the oil from my brand new Stang GT SOHC 4.6 engine for the first time. Car has 1018 miles on it. I've read plenty of varied posts here regarding when to change the oil for the first time, and varied responses regarding the whole break-in issue, etc. I just thought I'd report back on my own experiences. I drained the oil directly from the oil pan through an extremely fine strainer, then into a container. ZERO debris came out of the crankcase. That strainer was totally clean after all the oil drained through it. I remember reading one post here from a guy who drained his oil at I believe 500 miles and claimed to have found fairly large pieces of casting flash etc is the oil. Well, in my case, nothing came out of the crankcase other than oil. No solid debris of any type, at all. I then cut open the used oil filter and inspected the entire paper filter element. The largest pieces of metal debris were about the size of maybe a VERY SMALL granule of sand. There were about 20 of these tiny metal "granules" stuck in the filter paper. There were a few "slivers" of metal too, but VERY tiny, like a short nostril hair or something. All in all, considering that this is the first oil change on this new engine, at 1,000 miles, I'd say that very little debris came out. I expected more. Anyone else check this on their new engines?
