It's going to be a lubricant with nano particles in it, like nano sized ball bearings.
Millers Oils had engine and gearbox products out in 2009, and there was a lot of fanfare in the racing world but then I haven't seen much about it since. I know they've been working with a lot of teams in a lot of race series for evaluation, but not with a lot of advertising.
I'm not really sure I'd trust the claims of a product like this sold at a generic parts store. It's going to be a lot more expensive, and they're going to have to make big claims to justify the asking price. I usually consider consumer-grade products of this type that are made for passenger cars to be expensive snake oil, until proven otherwise. Could be amazing, but I'll wait for actual rigorous test results before I'll be convinced. Might work great for helicopters, and might not have any appreciable benefit to passenger cars. Either way, most everything I've even seen on lubricants with nano additives is related to highly loaded engines and gearboxes, and there is almost no real information on NanoPro MT except a lot of "It's great, buy it!" type of stuff on their web site.
Plus, sticking nano additives into every product that you can put a barcode on doesn't mean tangible improvements to all of those products.
I just have to shake my head at things like the coolant. If you don't have cooling problems with your stock Toyota Camry when you're using standard coolant in the standard cooling system, adding special shit to the coolant isn't going to net any benefits. If you do need to put special shit in the coolant to work properly, fix your cooling system. Your Camry is not a race car, and it doesn't drive around town at high engine load.
I'm also not a great fan of generic oil additives. Anything that you can put into your oil, any oil, is going to be a generic product, and is going to displace what is already in there. If the additive is that great, make an oil with it, and then sell that oil. Then you have an actual formulated product, not an additive product that supposedly works in any one of a huge range of independent oil formulations. I wouldn't readily mix different brands/types/weights of oils randomly in the same engine, and I wouldn't put a generic oil additive into the engine for the same reason.
