Anyone used ArchOil's AR9300 Nanoceramic? It's supposedly got a Coefficient of Friction of only 0.003, which is lower than any other oil additive.
It's 4 ounces for $49.95. Each bottle treats 5 quarts of oil, and the treatment should be done once a year.
Its component ingredients, according to ArchOil, are:
SiO2 42%
MgO 38%
Other 14.65%
Al2O3 1.95%
Fe2O3 3.50%
CaO 0.30%
Na2O 0.30%
TiO2 0.11%
MnO 0.09%
Think any of those would cause problems in our scooters?
