Sounds like everything is to spec. VW's typically take a straight 30 weight. I add a little ZDDP to my oil changes to put the zinc back into the mix.

I know several people that run 10W30 in the summer; 10w40 in the winter. Synthetics won't hurt anything, they just increase the chance of finding drips since they are a little "slippery-er" than dino oils. Add a zinc additive, though. Your cam will love you for it. I used to run diesel oil - straight 30 weight - until that formulation changed as well..

I wonder if the synthetics run as cool as dino oil? I know that synthetics cut friction and wear on parts over the long haul, but how well do they cool?

There's probably so little difference you'd never notice it. I've run both in past cars and couldn't tell the difference. The place where a synthetic made a huge difference was in the transmission - smoother shifting and a more positive feel, at least to me.

"Since synthetic oil has better heat transfer qualities than dino oil"

You answered the question yourself when you made this statement
"I know that synthetics cut friction and wear on parts"

I've been a believer in synthetic oils since I tore down the wifes 1990 corvette that uses only synthetic oil in it. When I got into the engine it looked brand new.(it had a intake manifold leak)

Yikes... 1000 miles between oil changes? First I've ever heard that...
