I doubt if actual nano-particles are being used. Not that small. If or when the FTC pays attention, they will cut and run. Snake oil.
IIRC Restore uses softer metals to fill score marks, groves, etc, to make a better seal between the rings and cylinder walls. God only knows what happens inside the oil filter, but I know a few people who used it in oil burning beaters and had positive results with it. You would have to add it every time you change your oil though. I guess for someone looking to get a few more months out of a beater, or who wants to off load a lemon it might be an alternative to LOS. LOS seems to have its place in helping to off load an oil burning knocking lemon.
