I switched my 95 over at 150K. I'm at 208,400 now without any issues. Mobil One with A/C Delco filters. I did run Castrol Syntech the first few times when I did the switch, I didn't have any issues with it either, I just decided to go with Mobil One instead. I wouldn't hesitate for * minute if that was my car.

When I still had my bonnes......the 95 I switched to full syn at about 201K without any issuses.....Car still run'* today. Best thing is if you have a high mile car, make sure you run a good synthetic like Mobil 1, or better yet, AmsOil....Amsoil I run in my dieseland with the filter I use I'm at a severe service change interval of 15K, normal service would be about 25K per lube/filter change
