Also varnish build-up - this is a potential significant issue. Any other performance concerns? Sythn seems so thin. I never use Mobile 1 on my 928 for instance. That car has never had even the slightest drip, but one time I used M1 and it leaked. Drained it and went back to my favorite brand of dino oil and never had another drip (although now I use Royal Purple in it with excellent results).
Anyway, my Boxster does not leak, so that is not a concern to me. Instead, it appears to my unscientific observation that dino oil of the same weight as sythn is "heavier" to the feel, or more viscious feeling.
Thoughts?

Synthetics are a different world; they have higher heat transfer capabilities than conventional oils, lower surface tension (hence your leaks), lower coefficient of friction, much higher shear capabilities, etc., etc. This is why they have taken over the high performance market. They are simply a much better product.
As for quieting lifters, as this problem is related to the incredibly small oil passages in the valve train oiling system, synthetics should do a better job because the flow more easily. One trick you might want to look at is to go with a higher film strength synthetic, replacing a 0W -r 5W-40 oil with the same brand 10W-40.......
