Shell claims new "FuelSave" gasoline formulation increases fuel economy

[aerohead]

If fuel injectors,fouled over time by mediocre gasoline could lose you 2% mpg,and you offered a gasoline with a detergent package ( like Techroline ) which could clean,and reverse the 2% loss,then,could you claim that the fuel 'improved' mpg by up to 2%?

...yes, but only until the "effect" wore-off and there was no longer ANY improvement because the injectors were finally "clean."

...however, because most drivers have 'short' attention/memory spans, maybe it'll work for Shell or Mobil or Chevron or Exxon...or not.

I've taken a look at the Shell website, it seems we're also getting what Shell calls Eurosuper 95 with Economy Formule, that's probably the FuelSave in the Netherlands.
