Which is the best fuel for keeping my engine clean?

Am I wasting money by occasionally purchasing Esso Supreme? I do this with the idea of it perhaps cleaning the engine and parts of my Mazda 5 Sport. I do only 2000 miles a year.
Switch to Shell V-Power petrol and use it all the time. You'll get more power, better response at low revs, and better economy if you use the better response at low revs to short shift. You'll also keep your fuel system clean.
