From your first link: Acetone operates on the unburned portion of the fuel through better vaporization to improves combustion efficiency.
If there is unburned fuel, it's going out the exhaust valve. How can anything that is going out the exhaust valve, improve combustion efficiency? Does the acetone go back in time & create more power in the (now spent) combustion cycle?
Again from your first link: Acetone further operates like an electron absorber.
Ask a chemistry teacher about how THAT works. I'm sure he'll have a good laugh at your expense. Where's the proof that free electrons are bad in the first place?
The whole article sounds like a bunch of buzz words stung together, for the purpose of impressing gullible people, and Ricers.
