    Is this stuff legit? Technically you could use a bottle of Dino and put one drop of syn and it would be semi-synthetic. Does anyone know more about this stuff. The Castrol semi-synthetic interests me and it is only $2.79. I know it's not Mobil 1 but is it actually any "better" than plain dino or just thinner?? Any schools of thought on this?
