Once I see my car heading to the 70s I get that special feeling inside I always have go for the perfect score! Great conditions this morning - no traffic, a mostly flat drive with some downhill.

I used some gravitational assist. Both Ufourya and F8L achieved considerably greater distances without such assist. But the Japanese hypermiler/commuters who achieved full tanks at 110 - 118 mpg -- one for over 3000 km -- are in a higher league still.
