Change to synthetic oil or not?
I just purchased a 1998 Tib with 92,000 miles for only $700. The prior owner who was the original owner used Pennzoil 5w 30 and changed the oil every 3,000 and I have the paper work to back that up. I removed the oil cap and everything looks very clean with no slug. At this point the engine is running great. My question is do I change it over to a synthetic oil with the amount of miles the engine has or continue using Pennzoil or some other mineral based oil. If I change to a synthetic oil at this point will it damage the engine or cause the gaskets to start leaking? I've always used Synthetic on my 2000 tib since day one.

If you want to switch that's fine it shouldn't cause any problems, but I would do an engine flush right before you change the oil if you do.
