Buster,

If oil analysis told the whole story, how would Terry Dyson ever make a living with his Tarot cards?

The Manual in our Saab 92x Aero reads the same way. The 92x Aero is basically a Subaru WRX in Saab sheetmetal. EJ20 4 cyl turbo. I initially put in AMSOIL XL 5w30 and am now running AMSOIL TSO 0w30 which my wife has noticed a slight MPG increase and also slightly faster turbo spooling.
