IIRC, they made five trips of one mile, but they measured after each and averaged them.
At 26mpg I get:
1 mile at 26mpg = .0385 gallons.
.0385 gallons x 6.25lbs/gal = 0.241 lbs of gasoline.
.241lbs = 3.86oz or 109g
At 29mpg I get:
1 mile at 29mpg = .0345 gallons.
.0345 gallons x 6.25lbs/gal = 0.216 lbs of gasoline.
.216lbs = 3.46oz or 98g
That's certainly a measureable difference.

Your right I forgot I still had my engine settings set on a four cylinder in my spreadsheet and forgot that my numbers are fuel flow per injector.
So my figures came out to be 106grams and 96 grams with a difference of 12grams based on a specific gravity of 0.728, in which is measurable but still way to small of an amount to conclude a accurate test.
I still need to see the show. Did they do a ABA test? Because I know for fact that the fuel injection system will hold more or less fuel then 12 grams based on fuel temps alone.
