Sounds like a bit of a marketing ploy....

In reading up on the product statement on BP's website, looks like it's just regular diesel with cleaning additives.

No increase in cetane rating, so doubtful you'll see any performance. The argument that a cleaner engine will go further and perform better is probably a contentious argument.

Maybe a tank every now and then to clean the system....?
