The German Syntec is for extended drain intervals right? So what exactly are those intervals? I still can't get over the nearly $8.00 a liter price tag.
What if my car is still under warranty? I still have to follow the manufacturer’s recommendations don't I? I'll bet that GM doesn't have extended drain intervals.
