A lot of the customers that I have worked on their mercedes have told me they had a model a in college, that they drove in the 55-65 range "all the time"---but the average time was low because they had to stop for oil every 100 miles---used oil

my own experience is that a bad rebuilt engine had trouble with 55,poor fuel mileage (15 mpg) rebuilt closer to original specifications I found that 65 all day was possible, along with good fuel mileage ---over 20 mpg at those speeds with stock head and rear ratio
