Put simply, it's not an easy chemical process to do. Nissan say they are the first to do it.

The MR16DDT isn't that economical as it's more oriented towards power. But I've been in cars with them in and the engines do feel very much smoother than conventional non-treated engines so I have to admit that I think they have achieved what they are claiming.
Coatings like this have been around decades, they are good for several percentage points improvement but having a car that gets terrific MPGs for 20-50000 miles then tapering off would likely create backlash
