Like I said before, NO ONE can match the R&D money and resources of ExxonMobil, one the top three corporations in the world! Not Amsoil, not anybody else. As for brand recognition, why would one use Mobil 1 if they were not paid by the sponsor? Because its better. As for QC, Amsoil gets what's given to them by the suppliers. These same suppliers probably sell to a slew of other oil companies marketing sythetic motor oil.
