Probably wondering whether you meant an Imperial Gallon of 4.55l or an American Gallon of 3.79l a.k.a. the old Wine Gallon.
(My old 80’s beater, which was basically an upholstered roller skate, got 52mpg in 
, but only 43mpg when I was in the 
)
I challenge you to find in , at least since the FTA/NAFTA/USCAM, a real cup measure that’s 284mL instead of an cup at 239mL. Never mind that 
cup measures seem to split the difference at 250mL. 
That’s one reason Grandma’s old Empire-days recipes don’t work, eh?
