It is said that the reason Germany attacked the Soviet Union,

They lost because no Guderian

They tried, they couldn't produce enough with the technology of the day

they did and spend an insane amount of resources in this scheme - it wasn't enough tough

after the allies started to systematicly bomb the factories in 1944 the supply dropped sharply and with it the mobility of the german army

They did, but it was the one industry most susceptible to strategic bombing.

>In the first quarter of 1944, synthetic fuel plants located near rich coal deposits in the Ruhr, Silesia, and central Germany, around Leipzig, produced over half of Germany’s total supplies of oil, 85 percent of its high-grade motor fuel, and nearly all its aviation gasoline. Even today, no country’s synthetic oil industry comes close to Germany’s peak wartime production.

>Although Germany’s synthetic energy plants were scattered all over the Reich, a high percentage of petroleum production was concentrated in a small number of Bergius hydrogenation plants that were the sole source of Germany’s high-grade aviation gasoline and most of its motor fuel. Nearly one-third of Bergius production was concentrated in just two plants: Leuna and Politz, in Polish Silesia, and over a third more in five other plants. Earlier in the war, Speer had lived in mortal fear that the Allied air staffs would target Germany’s perilously grouped synthetic plants, which were too large and complex to be dispersed. When the plants were finally bombed, Hitler publicly rebuked I. B. Farben’s Karl Krauch, his chief minister of chemical planning, for organizing the industry as if to invite its own destruction from the sky. Yet it was Hitler who had encouraged the economic integration that made German synthetic production overwhelmingly efficient; and he had done nothing to discourage Hermann Göring’s misplaced confidence in the Luftwaffe’s ability to shield these plants from aerial annihilation.

>After the war, Speer told American interrogators that a full-out offensive against the synthetic plants by the combined air armadas of England and America—closely spaced raids, night and day, without cease—could [alone] have brought about Germany’s surrender... in eight weeks.”

Even with significant investment into synthetic production, they still had shortages throughout the entire war. Not only did they have to supply their own population and armed forces, they had to supply their allies and occupied territories also.
This paper is a good overview on how oil shaped Britain and Germany's strategies in both world wars:
