How long ago did you make the switch or when did you last check the 0w20? If it was before winter than you may just be seeing the difference in winter gas formulations. Up north, we all lose a mpg or 2 in the winter.
Setting aside weights for a moment, I would not be concerned very much about meeting VW special specs. I think that the Euro deal of each manufacturer having their own oil specifications is pretty much a scam. Any synthetic oil changed at reasonable intervals is going to protect your VR6 just fine.
Those of you who have a mild stroke at the thought of using an oil in a VW which is not "approved" are just being sheep. Baaahhhhh.
I like TooSlick's recommendation of running Mobil 1 5w30. It is almost as thin as 0W-20 and should give you most of the fuel economy back whilst not making for sleepless nights over the use of a "20 weight" oil.

Your right John,my oil mania has gotten to me
!
TS is right about Mobil 1 5W30 being the best compromise.This is what I intailly put in the car when I got it and I really liked it's performance but that darn "gotta have that A3 rating for VW's" got in my brain.I cast you out now
!
I like the fact that it's a very thin yet very shear stable 30W oil.
Plus I can get it for $3.73 cents a quart at my local Costco
!
To the one unfortunate 6 pack of Mobil 1 5w30 I pickup today,your SM rated azz is mine!

The VR 6 seems to like heavier oil.
Also the new ones have low tension piston rings and if you continue to use M 1, 0w-20 you could start burning oil. Certainly you will get more 'blow by'
with the thin oil on this motor.

Alas,after much thought
I have decided to go back to the green.
I was quite pleased with it's overall performance in my VR6.Good fuel economy,cleaning power and an impressive UOA.
Man,why did I ever sway from this stuff
?).
Nosmo,
Mine is a 2000,is that a "newer" VR6 with the lower tension rings?

Yes.
You were lucky to buy a car that is/was quite a bit ahead of the curve in 1986 in terms of fuel economy. Because most cars sold that year of that size were sitting in the 20mpg range, give or take a few MPG. Of course those Audis weren't/aren't cheap, nor is maintenance when required. You were also very lucky to be owning that vehicle during a period of declining energy prices -- just to get back to 1981 levels, oil would have to be at least $80/barrel.quote:

The expected outcome won't be that bad if, for example, today you buy a 50mpg diesel and drive it till it dies. But if you buy the average new car today, most of 'em don't even break 34mpg on the highway. Hence why I put 8-10mpg in the example -- 20 years from now average midsize car will be getting 60mpg, which is like going from a 15mpg car to a modern 30mpg car.
