I have alwyas used Mobil 1 Synthetic and I have been involved with the reviews Patman has discovered about oils. But I have always been curious to which is the better oil between the two. Royal Purple Synthetic or Mobil 1 Synthetic. And is there a difference in Royal Purples Racing Synthetic. Thanks Zoran
