went to true value ATC yesterday and looked around for synthetic oils...how would you know kung totoong synthetic oil? I mean iba-iba nakasulat eh, meron 100% synthetic, yun iba fully synthetic, yun iba naman synthetic lang nakasulat...

so among those na nabanggit ko ano yun totoong synthetic dyan? kasi I assumed na dapat 100% synthetic ang "real" synthetic...tama ba ako?
