Your A4 owner's manual states that during the first 1000
miles, do not accelerate at full throttle or exceed 3/4
maximum speed (which I presume to be engine speed), so
the gist is to avoid revving it over 4000 rpm or so.
Conventional wisdom also says to keep changing revs as much
as possible (like shifting up and down through the gears).
For the A4 V6, that range would be from 2000 to 4000 rpms.

I think not, as the first factory recommended change is at
7,500 miles.  Most break-in oils are not intended for such
long use.

You can observe the factory recommendations, or you can change
it early... it can't hurt.

Audi says 1000 miles, but I think it's more like 2500.

Synthetic oil is great, but don't use it until your car accumulates
a few thousand miles.  I recommend going with conventional oil
until the first 7500-mile change, then use synthetic from then on.
