Did you change viscosity? If not, I'd be concerned if you could "feel" the difference after a change - it would mean a perceptible difference in engine friction and that would imply significant wear exposure before (I presume you mean it feels better now). I'd do more frequent changes in the future and just keep repeating to myself "placebo effect" to keep my thoughts off of what could have happened up to now. I'm doing 1 year/~5K miles (works out to about the same thing for me) with the synthetic (DD w/conventional gets 3K).

Is 10,000 miles/1 year too long an interval?
I think Porsche claims 15,000 miles.
