Very good mpg numbers, my glc63 averaged 29mpg doing similar speeds, averaging 55mph with cruise control set at 62mph doing a round trip for over 2 hours.

29mpg is amazing for a biturbo V8! I like your numbers better

it also shows you were doing 42 mph at the time of the photo, which I assume you didn't do long or you'd have to have had some time at 82 mph to keep your 62 mph average, and that would have eaten into your mpg#.
