Just changed it for the first time at 504 miles a few days ago, with Mobil1 0/30, and OEM filter, plus a GoldPlug magnetic drain plug. Wanted to wait 1K, but I'm in the middle of a long trip, so did it earlier. Will do it every 5K miles after that, like I do with all my vehicles, mostly due to many short distance trips. By the way, the oil filter is tiny on this vehicle, so I wouldn't go beyond the 7,500 Hyundai calls for.
Finally, found a drop of oil on the bolt shown with a blue arrow, and the other picture just like it shows there, but with no trace where it came from (they're not my pictures, I may add). And my oil was still clear, since it only had 504 miles. Found several more cases of bad crankshaft seals besides those 2, and I'm afraid that's exactly what's happening to mine

. Didn't see evidence of the leak, but cleaned everything perfectly, including removing that bolt (no oil in there), so will check it again after my trip, to see if by any chance it was oil from somewhere else, but after several instances of bad seals, I really doubt it. Will report on what I find soon.
