Just circumstantial evidence. I have 3 cars that the engines have failed on. In all three I was running Mystic. The reason that I was using Mystic is because they all burned/leaked so much oil that I couldn't afford synthetic. So, because they were oil-consuming engines, they were probably not in very good shape. But after the third engine began to get worse I said "Hey, maybe it's the oil!" and choose to pay the couple dollars more for Mobil or Delo (still dino oil) from Wal-Mart. That third engine is out of service because of head-gasket problems. My conclusion - the oil _may_ be fine, but _for_me_ its worth the small price difference to put in oil that I have a bit more confidence in. Philip, not an oil expert
