With OCIs that long I would be real nervous without either periodic (5K
miles?) filter changes and/or a bypass filter. But that said a good
synthetic really should be able to go 15K miles without issues, I
suspect other problems with that engine like a nonfunctional PCV valve?
Personally, I change my oil every 5K (Porsche 944) with either Mobil 1
5W40 or Rotella T syn 5W40 even though the owner's manual says 7500.
Maybe I'm being over-cautious, but I can't be arsed to mess with used
oil analyses and without same I just get nervous.
