I work for a large oil refinery in the UK, we supply lo sulphur petrol and diesel to just about every forecourt in the north of the UK, this is simple economics. You go to a shell garage or the bp one across the road and you'll probably be getting the same stuff. The supermarkets are cheaper as they don't play ball with the oil majors and buy from spot markets, so you don't know what your getting there. I run my VR6 on any 95ron as using 98ron cannot justify the price hike, 98ron was initially designed for large high performance engines and should give you a little more torque in a VR6. Ultima
