My mechanic uses Total Quartz 9000 5W40 in all of the cars he services (he only works on European cars). My Mini burned a little oil so I stopped by to pick up a quart as he is the only local shop I know of that sells it. The bottle he sold me looks exactly like this one: https://www.amazon.com/Total-185703-12PK-Quartz-Energy-Engine/dp/B00LAY8J94 So the bottle says "Advanced Synthetic Motor Oil." Does that mean it's not synthetic technology or whatever they are saying these days, but actually a group IV base? Just curious. My mechanic swears by the stuff. Thanks in advance.
