VPower FTW, increased economy almost pays for the extra cost. Plus you get a little bit more power, cleaner fuel system, cleaner combustion chamber, cleaner O2 sensors and cats and longer life for them, cleaner emmissions. Even in the old days of Optimax instead of VPower when I had 1990 1.8 Passat I was using premium Shell juice.
That being said I don't see much difference with premium fuels on diesels.
