Need more comments on your driving conditions. Do you make a lot of short trips? Did you bring the engine up to normal operating temp. before taking the sample? If no and yes, the fuel is likely just the result of the tune running a little rich for safety.

Are e-tunes or any type of professional tune offered for the OpenFlash? You're probably fine with the OTS tune, but a protune will probably dial back some of the fuel. You could also bump up the viscosity and just run oil from Wal-Mart and change it more frequently. A GF-5 5W-30 (OTS Mobil 1, Pennzoil, Castrol, etc.) will shear to a 20 grade anyway (also will be a 20 grade from fuel contamination) so the oil will not be that much thicker.

If you stick with Amsoil, I would go with OE or XL since SS is really for extended intervals.
