My W116 is supposed to have a 3.07 diff per its stamping...yet it turns far more rpms at 80 mph than my W123 that also has a 3.07 diff....about 800 rpms more. Why nobody can explain?
But my Heavier higher reving W116 gets 25 MPG very regularly...where my lighter lower reving W123 gets 20-22 mpg driving the very same route under identical circumstances........
