My VR6 was halfway to minimum 3,000 miles after service. 75k fsh no smoke etc. Oil consumption is normal on older larger engines.
Although a full dipsticks worth in a month is quite fast. I wouldn't worry though, just have a good look for leaks and check the levels more often.
Personally i wouldn't leave the same oil in a vr6 for more than 5,000 miles as it is vital that the timing chains are well lubricated.
Just another money burning joy of having a vr6.
I bought an oil filter at vw, while i was there i picked up an 8v GTI filter for a mate. My filter was ?13 his was ?6.
