Japan is a resource-poor country, and during World War II, Japan's advantage over the attack on Pearl Harbor lasted only half a year before it was gone. After Japan lost its maritime supremacy in the Pacific, oil could not be transported back, and a very serious oil crisis occurred.
When the Japanese reached the end of their ropes, they had a lot of ideas, the most typical of which was to mobilize men, women and children to dig up the roots of pine trees, a campaign called the "Pine Root Oil Emergency Production Campaign".
Because Japanese experts have discovered one thing, that is, the pine root has a high oil content, which can be boiled out of pine root oil, and if these oils are distilled, then light oil can be obtained, and then stirred with a little alcohol, then it can be turned into pine root gasoline.
But Matsune gasoline is a very garbage thing, because its oil is very poor, the viscosity is very high, and it is also prone to carbon deposit, which is especially easy to scrap the machine.
The Japanese can't help it, everyone knows that Matsune gasoline doesn't work, but it's much better than nothing.
At that time, Japan's slogan on "Matsune Oil" was "200 pine roots can make an airplane fly in the air for an hour", and before the collapse of the Japanese militarism, the Japanese could drum up 70,000 barrels of "Matsune Oil" every month. But this thing is a drop in the bucket compared to the production madness of the United States.
The "Matsune Oil Emergency Production Campaign" was a black joke at the end of World War II, and Japan, which was weak in national strength, was unable to do its own power, and started the war in vain, and finally ended up being baptized by the atomic bomb, which can be regarded as self-inflicted.
