hello everyone, have a syntec question for everyone, Ive been using the German castrol 0w30 and i really like it 7500km OCI drained today still wasn't too dark. Now i know this is a real Group IV PAO/ester basestock and im paying for that! My question is i know the other syntec isn't group IV i think i remember reading its Group III is this correct ?????
Also is the other grades of Syntec(us) as good as the 0w30 syntec(german made)
