I can understand their caution as it's undoubtedly a minefield and the least said (or claimed) the better. IMO Shell have watered the benefits of V-Power down to the point where no-one could argue it wasn't doing what they claim, but it makes it difficult to justify the price differential as it isn't claiming anything different from their regular Diesel. Shame.
