Quite possible I think. To get the best power & torque out of a competition engine it has to be mapped to suit the fuel; if we change the fuel we change the mapping. I see no reason why the same would not be true when trying to improve economy rather than performance. I assume you do not change the tune of the car when you change fuels. If the set-up on your car happens to suit V-Power this might explain the results you are getting. So perhaps the conclusion is that it is the combination of fuel and car which is important and changing to V-Power could be a good move in some cars but not in others.
