oil additive, just like dura lube and all the other stuff.
i personally don't trust the product. yung duralube and most fuel additives may kaso yan sa ftc (? or is it fcc) :roll:
d kaya stucked na talaga sya dun, hehe.
meron akong nabasa before, yung test na ginagawa nila na pinapatakbo yung car or whatever engine without the oil. kaya daw talaga pero pag binaba mo yung makina grabe and wear and tear.
based on what I read and hear walang kwenta yan mga additives, pero if you see the infocommercial ng X1Ra nakakabilib din dahil tinggal nila ang motor oil ng plane while flying
