Care to elaborate? I've always used synthetic in my 5mt, I've seen a 5mt subie run for over 250k miles on synthetic, and I know several people with subies that will use nothing but synthetic in their 5mt. Maybe specific brands and/or weights, but I've never heard of a synthetic damaging a 5mt strictly because it was a synthetic oil.
