BUT only if you like high amounts of viscocity index improvers which are not good for your engine; especially high revving ones! Mobil 1 5W30 uses NO V.I. Improvers... Yet another reason why I chose Mobil 1 over AMSOil.
Demon, definately not so. To make claims is quite different from living it. I've been driving my SVT w/AMsoil 0w30 Full Synthetic Racing Oil as mentioned in the DMD topic for most of my now 53,000 miles. I've put on, I can pretty much guarantee this, more real racing miles than most any CEG'er or Contour owner around and If people claim such catastrophy in high rpms with our motors it's quite strange that an oil with such viscosity improvers has kept my motor running strong, even under the CLAIMED high stresses put on by an UnderDrive Pulley.
As I said in the DMD topic, AMSOIL, AMSOIL, AMSOIL!!!
Greg by the way, Mobil 1 had significantly worse wear than even Castrol Syntec on a 4-Ball Wear Test, Mobil 1 Tri-Synthetic 0w30:
.607....Castrol Syntec 5w30:
.576....But none of the popular synthetics could compare to Amsoil Series 2000 0w30:
.373 (the smaller the wear scar the better, so the lower the number the better). Tests were done at 40kg Pressure @150deg.C, 1800rpm for 1hr duration. A professor at the Universtiy of Hawaii did tests on many synthetics, there wear and breakdown properties and Amsoil along with Synergyn came up at the top.
