We've owned VW vans for over 30 years and have never used anything but regular!!  We buy whatever brand is cheapest!!  You usually see the same gas trucks filling different stations in town.  Only difference might be like Chevron, Standard or Shell who supposedly add things to their fuel, but personally I don't think their high prices justify using them!!  We had Cadillacs a few years back and even used regular in them (even though they say not to with the V8 engine) and they worked fine, too!
