a little bit confused dearest paps....been used to Delo Gold ISOSYN brand....want to confirm if what i bought (Delo gold multigrade isosyn) is a mineral, semi-syn or fully-syn? my thought is that it is a Group 2 mineral oil refined by using the so-called "ISOSYN" of caltex.....

long story short, a mineral oil refined using refining technology intended for synthetics...am i still on the right track here?....btw, i prefer mineral for some personal reasons and a little bit of technicalities.....
