Well, maybe, but I don't tend to let it lie when a mathematically absurd statement is made here. We don't need BITOG getting the reputation as the place that recommends adding a pint of PYB 10w-30 to get an extra few percent in fuel economy. My G37's fuel economy changes by grade cannot be measured outside of the error bars.
And no one here, outside of a lab, measures their fuel economy without an error bar of 10% or greater. Gokhan's 15% estimate is probably more realistic, especially if at least something isn't done to control other variables. 10% is basically measurement error alone.
I'll let someone else explain basic significant figures this time. People believe rat gets 6 significant figures on his magic machine, so I suppose it shouldn't surprise me that they believe that gas pumps can read to the nearest millilitre.
