I was just looking over the Maxima.org oil analysis spreadsheet, and on the virgin oil samples I noticed that Castrol Syntec contains 571ppm of magesium while the GTX contains zero. What does the magnesium do exactly and what advantages does that give Syntec over GTX? I had always assumed that Syntec and GTX had the same additive package, with just a different base oil, but I guess I was wrong. (write this down on your calendars it doesn't happen too often)
