Hey like the title says which would be better i have been running Mercury Quicksilver PWC 2-stroke oil (API-TC rated) in my Kawasaki JETSKI and in my KDX and YZ for a little bit now should i only use TC-W3 in my dirtbikes because API-TC is a Higher grade oil i know if you run TC-w3 oil in a SEADOO you will burn up the engine (thats why i think its higher grade) so what should i do? thanks
