Any petrol is fine mate, no need to worry, some do have additives or higher RON rating (measure of the concentration of energy in the fuel) that your car may, or may not, run better on, some cars will show an increase in performance and some won't, it's a bit of trial and error to find one you are happy with, none of them will harm your car.
I generally buy supermarket petrol and have done for decades as it is generally cheaper (and Morrisons is the only full time petrol station in my town), I have never had any issues as a result of using this so I can only assume it is all fine or half the town would have broke down cars.
