Here's some interesting reading... It has been circulating around most air cooled based bulletin boards for several months but for some reason, it hasn't made it here so,,, I suggest you read the article from the below listed link::::

The bottom line is that the Govt. is mandating that oil companies remove zinc. Zinc is a major lubrication contributor
As a side note, I just ordered a case of GM's EOS, part number
1052367 see: http://www.gmpartsdirect.com/results.cfm?singlepart=1&partnumber=1052367
I also concur that the Shell Rotela oil along with the EOS is probably the oil you should be using in your VW based engines.
As per the article I posted, check to make sure that the oil hasn't been reformulated with less zinc before making a purchase. If your favorite oil has been reformulated, check the chart and buy oil with a high zinc (Zn) and phosphorus (P) count.
