That's not what we're discussing; we're discussing the distribution of fuel already in stockpiles to front line units: Tanker trucks.
News to me. I thought we were discussing your point that "air interdiction by allied fighter-bombers almost completely shut down the German transport and logistics network." It wasn't the fighter-bombers that shut it down, it was the heavies. Germany didn't transport fuel from Romania to Normandy in tanker trucks.
I note, while I'm at it, this passage from Williamson Murray's "Luftwaffe," 1985, The Nautical & Aviation Publishing Co. of America, Inc., at page 268:
"At the end of June [1944], the Luftwaffe's strategic position, as well as the Reich's, gave the Germans small cause for optimism. A Luftwaffe intelligence report summed up the situation. While Allied air operations over Germany had declined due to the invasion, the authors felt that Allied bombers would soon return to Germany. In France, air attacks had destroyed the transportation system, while bombing attacks in Germany had extensively damaged the fuel industry. Production of aircraft fuel was off by 70 percent, synthetic fuel production was down by 60 percent, and refinery output (including Rumania) had dropped to 70 percent of total capacity. The report noted that aerial attacks on transportation and petroleum industries had provided substantial aid to the ground battle in the west. Particularly worrisome from the German perspective was the possibility that the Allied air forces might do in the Balkans what they had accomplished so successfully in France and Italy; that is, destroy the rail and road system. In conclusion, the report warned that the great danger was a continuation of attacks on the synthetic fuel industry. Thus, the German high command needed to provide adequate support for the great fuel plants. Attacks on transportation were almost as dangerous, but there was little that could be done because one could not protect an entire rail system." The report reference is to Oberkommando der Luftwaffe, Fuhrungsstab Ic, Nr. 3080/44, 16.7.44, Nryt.: "Britischnordamerikanische Luftkriegsfuhrung gegen Deutschland, " Imperial War Museum, Speer Collection, Roll #21, FD 3046/49.
As it had been on the Eastern Front, air interdiction and CAS was the best use of the Allied air forces. The Luftwaffe knew this and after Normandy they prioritized attacking Allied fighter-bombers and medium bombers over the strategic bombers.
Educate me. I've never heard of any such formalized prioritization. And I question the conclusion that this was the best use of air power in WWII. Until forward air controlling was well-developed - which didn't really happen until Viet Nam - close air support was a chancy proposition. I can't think of any battles in WWII, in the west, at least, where close air support was effectively employed during a ground battle.
