The 11s is synthetic.  Other than that, very little difference.  It's kinda
like the difference between dino oil and synthoil.  There is very little
difference between the products.  Used comparably with reasonable
distance/time between changes either oil will serve nicely.  The 7.1 vs.
11s decision is much the same.  When your car was made the 11s variant was
not available.  Therefore the 7.1 version is the one for which your car was
designed.  Should you use only the 7.1 and not the 11s?  It makes little
difference.  The 7.1 is a little less expensive.  This is probably the most
important single fact upon which to base this decision.

Answer me this: which cartridge/rifle is better suited to killing a deer at
30 yards?  A .30-06?  Or a .270 Winchester?  The answer?  Who cares?
Either is more than capable of doing the job.  Either is preferable to the
front end of your Audi.  :-)  You pays yer money and takes yer cherce.


>2)  What is Genuine Audi Goo2K closest to-7.1 or 11?

Audi uses the same part number for both.  Audi regards them as essentially
identical and therefore interchangeable.  You pays yer money and takes yer
cherce.


>3)  What is the compatibility between 7.1 and 11?

Rumor has it that 11s can replace 7.1 but not the other direction.  I'd
wager the replacement can go either way with no concerns for the car.  You
pays yer money and takes yer cherce.

I have no definite information on this product, but it is likely that it is
a viable substitute.  If the viscosity and viscosity temperature
coefficient and effect on seals, etc., are the same then one can substitute
for the other with little likelihood of problems.  You pays yer money and
takes yer cherce.
