Is using Shell V-Power once every five tanks worth it?

Is a tank of Shell petrol V power every 5th fill worth it? Does it have a decent cleaning effect over one tank of fuel? Should I go with it consistently?

Using the odd tank of premium fuel is better than none at all, but to get the maximum benefit it would be worth using it at every fill up if this is a viable option. One tank would likely have a small cleaning effect, but five tanks of regular fuel might be enough to undo any potential benefit.
