Anyway I intended to say 12 km/liter, that is what I get when towing the stacked trailer at 100-110 km/h.




I just looked up that a gallon is 3.78 liters The speed of 100 km/hr. is about 62 miles per hour. That 3.78 liters will take you 45 km. (45 km./gal.) or 28 miles per gal.

Those numbers don't sound unrealistic. Your 15 km./liter is 35 miles per gallon. Also reasonable. I drive a 240D MB that I get 31 miles per gallon at highway speed of 65 miles per hour. That is 105 kph.

Conversions are always a problem. In Canada they use the Imperial gallon which is about 5 liters. In weight, there is the metric ton. the English ton and the American ton They are 2204 lbs., 2240 lbs., and 2000lbs. respectively.
