Probably just a fancy marketing term. Bet it is has whatever brand.... Oronite, Lubrizol, Infineum, Afton.... additive and blended next to dozens of other relabeled brands.
Waiting for someone to market Pico, Femto, or Atto additives......
These new Nano additives are so 'blah'
I have done 2 voa on racing 5w-30 and 5w-50. Search voa section. I've used gallon of 5w-50 and 1qt of Motul 5w-40 ll-01 in his boosted stage 2 wv GTI, unfortunately car was sold before I could take sample for uoa. It seemed it used less oil.
I still have 5 gallons, will brobably use as top off and mix with something--to much zzdp.
He suggested a 10w30 over a 5w30 when over 100k miles.
As for the 50/50 mix with Group III/Group IV, I certainly don't have have the expertise to know if that's the optimal choice (it does sound cool to me, for what it's worth). But, if you're over 100,000 miles, don't bother with 10w-30, just use MaxLife.
