Anecdote time. Back in 1981, I was living in New York, and owned a Camaro.
I went to live in England, taking the Camaro with me. I expected the
numerical miles per gallon to increase by roughly 20%, since the imperial
gallon is 20% larger than the US gallon, and my driving mix was similar.
In fact, it actually increased by 44%. A year later, I went back to the
US, and the mpg dropped back to its former value.
