Synthetic, for me???

[JasonNagra]

Okay I did a search on a few forums about this question before I posted. Anyway, my 91 S13 has about 128K miles on it. The car has always been a daily driver and has never seen synthetic oil, just regular old GTX 10W-30. Well now that i am the owner of the car I track the car about once a month, and Im pretty sure i push the car harder than the previous owner considering she was an older woman. Anyway what I was wondering was, would it be wise to switch to a full synthetic oil (same weight 10W-30) on an engine with this high milage? The engine is in great condition, and the compression is excellent on all four. I was just wondering if it would hurt anything, because I had been told that an engine that has been saturated in conventional oil its whole life, can hurt the engine if switched to synthetic. This is what I heard and I do not know if its true or not. Sorry about the long post but thanks in advance. Thanks, Jason.
