Van Creveld Supplying War Logistics from Wallenstein to Patton 1977 2nd edition 2004 says that the DAK panzer motorised divisions used 350 tons a day unfortunately I can t find a figure for infantry divisions yet though as the DAK divisions were all motorised it may not help directly Certainly the figure of 1 100 must be an American estimate based on lavish US usage not on actual German usage which was much less than the American The Germans used 200 tons a day while retreating from Normandy is what the web sites say
