Since the 1.8T recommendation is 'premium', I would assume that the
same would apply to the 2.0T. I have heard that you can use 'lesser'
grades with some performance and mileage decrease (as Pete noted) but
considering that the performance is just adequate with the 1.8T, I
would not want to degrade it at all!
I really want to chip it once I get closer to the end f the warranty.
