With synthetic, definitely wait for mileage. 6 months is nothing, IMHO, if you haven't driven the car much.

Default I'd avoid going more than 10-12 months on a change of synthetic

No particular reason other than that I get very nervous at that point.

Default M1 10W30 consistently tested nearly "as new" after 7,500k and 10k...

in my '98 A4 Avant 2.8, '01 A6 Avant, and M-B C280... based on used oil analysis.

I change at 6 mo/5k but you can let it go 12 mo. and 10k and probably be fine in a non-turbo if you want.

Yup. I'm starting to do 5k intervals as well, though I use M1 5w-30.
