The word "Synthetic" is roughly interchangeable with the word "Modified" and its useage. To illustrate: You want to sell a modified car. The person who responds to your add is going to ask "What vehicle is it?" and "What has been done to it?" A cheap car with a free flowing exhaust added is a modified car. So is a GT3 Porshe. The reality is that oil companies try to give high end impressions while keeping to a minimum the molecular modification of the most economocally viable mineral basestock. The best base stocks available in the automotive world are Poly-ol-esters which are very expensive, The cheapest is a barrel of crude bought straight from your nearest oil well. Everythging else is in between...

COULD WE CALL GROUP III BASE OILS SYNTHETICS?
WAHT SHOULD BE THE LEVEL OF SYNTHETICS COMPONENTS IN FINISHED OIL, SO WE COULD CALL THEM PARTIAL SYNTHETICS AND FULL SYNTHETICS?
