Not sure if this is "premium gas" or not but I tend to fill up at supermarkets over here in the UK as they are cheaper.

Some on forums related to the Aygo suggest fuel from branded garages (e.g. Shell, Esso etc.) results in better MPG and I intend to try a couple of tanks to see if there is a big difference.

Most Petrol in the UK comes from the same refineries, and the differ in terms of added chemicals for cleaning, octane boosting and so on. Supermarket fuel is the basic blend, branded fuel has more additions - maybe.
