Hitler had a positive obsession about oil. Much of his transport was horse drawn right up to the end of the war and he could see it was his motorized troops handing him tactical victories. His armies were never able to even replace the motor transport the lost in 1941, and much of that was captured French & Czech equipment.
He bungled by playing prestige games with Stalin at the city on the Volga - that divided forces with which he could have captured the Caucasus and he'd have been drowning in oil.
Guderian rebuilt the panzer forces and had created an armored reserve 1943 but Hitler threw it away on the badly flawed Kursk offensive. They were never able to put anything like that together again.
The Germans were actually making synthetic fuel by war's end but it was not nearly enough. Most of those 'big cats,' the Tiger and Panther tanks, ended up abandoned. They were ok in a fight but drank way too much fuel.
Post war it looks very much like if we (and the Brits) had focused our bombing attacks on a specific industry, such as ball bearings (Schweinfurt Raids) or petrol (Ploesti and others) the air force could have achieved a strategic victory. (at least according to Albert Speer)
Much like the Luftwaffe raids on the UK ('the blitz') the Terror Bomber raids killed lots of civilians but just pissed people off enough to keep fighting.
As to jet aircraft? The Me262 was actually flying against by war's end but most were captured intact on the grand for lack of fuel and engines wore out fast. They could have been devastating but Hitler delayed production so they could be outfitted as fighter-bombers when what he really needed was fighter planes to interdict our bombing raids.
They showed up again not long after, cleverly disguised as the Mig15 in Korea!
Please forgive my long tedious posts on this topic. I was planning to be a Military History Professor before I found college so boring I dropped out and joined a band! But I never stopped studying.
Ted actually rescued my personal library when I somehow locked myself out of it!
