I keep hearing wonder stories about it, and I haven't really seen it either.
Oil is oil. Synthetic is just BETTER oil. If the engine runs quieter or noisier, it's because of a change in weight and possibly quantity.
Shifting WILL be smoother with fresh oil, and it degrades so slowly that it's hard to feel until you finally realize that you've missed 3 shifts "this week".
But it'll be smoother with fresh dino too.
