Is the Golden Wheat Pool Energy Saver Really Useful?

The working principle of Jinmaichi economizer is to stabilize the ignition voltage of spark plug and make the engine oil sprayed by injector burn fully, thus achieving the effect of fuel saving. This principle is correct. But plug this thing into the cigarette lighter to control the voltage when the ignition is stable. That's an exaggeration. Nowadays, the engines of cars are all electronically controlled. To change the ignition, at least some computer programs or ignition coils should be changed, but some circuits should be changed, otherwise there will be fault codes. You said that the cigarette lighter is only a live wire and a ground wire, and it is not controlled by the computer version. How does it accurately transmit the output signal to the spark plug? They have nothing to do with each other. Jin Maichi said that in order to stabilize the vehicle voltage, it is a myth to connect two wires to stabilize the vehicle voltage. The fuel saving effect of Jinmaichi at 30 km/h is 16%, and that at 60 km/h is12%. 95 km/h at high speed saves fuel by 9%. The average fuel saving is 9%-22%. If it really has such a good fuel-saving effect, the current gasoline should be one liter of 5 yuan. Imagine that crude oil only lasts 50 years for the earth, because you invented this economizer, and now it is enough for human beings for 60 years. Then it is estimated that you will be the richest man in the world in the next 50 years. China's automobile level has been a big step ahead of the world, so it is not impossible to produce several truly independent brands by now. In fact, I have seen an advertisement for this product on CCTV, and I really doubt my judgment, because I have seen such an advertisement on local TV stations before, but after consulting professionals, I found it to be false.
