Ok, I got one for you guys.
I have a Protege 5. 2L motor/5 speed, and I drive the stew out of it. I put Royal Purple 5w-30 in it at 5000 miles and now have 6600 miles. In the last 100 miles I have noticed the motor is running a lot smoother. This motor is known for vibration - very noticable at 3000 RPM. I never had to look at the tack to check RPM, but now I do. Really smooth up to 6500 RPM. I have been running synthetic for years (Mobil 1) and have never experienced this.
Engine just breaking in? Synthetic oil? RP oil? Too many beers? Sun in my eyes?
Phil
PS - the P5 is a HOOT to drive around the twisties very fast
