Should my son use Shell V-Power in his Audi R8?

My son has recently bought a Audi R8 and I have told him to use Shell V power. He seems reluctant to use it on the grounds that the fuel consumption is already poor without adding the extra cost of premium fuel. Do you think the extra cost of this fuel outweighs the long term cost. In other words will he see a significant mpg improvement as well as the engine benefit to justify it.

So he's bought a £100 grand car and he'd reluctant to spend 8p a litre more on fuel that will give it an extra 50 horsepower, keep its fuel system clean and pay for itself with better fuel economy. He must have won the lottery.
