Zimnismoboy34, Greetings from North Carolina.
In the past I experimented quite a bit with octane boosters.
As others have posted, most commercial products sold as octane boosters are slightly better than useless!
I used to use 104 plus (MMT) at LARGE concentrations $$$ in a non emissions controlled application.
(As much as four 8 oz cans to 5 gallons premium unleaded in a "street legal" 13.5 to 1 compression race motor, fun times.)
This gave good results with the exception of fouling plugs occasionally.
Of course this concentration would wreck a catalytic converter and foul the O2 sensor in short order.
By far the best results I have obtained were with aromatic hydrocarbons.
Specifically Xylene and Toluene.
These are sometimes used as paint thinners and may be found at paint supply houses.
Alternately they may be purchased in bulk from industrial chemical supply houses.
The aromatics (are) were standard additives for octane enhancement in years past in fuels sold to the public.
So adding aromatics at up to 40 percent has been reported to cause no issues.
(I have added at this concentration and more!)
I would advise you start with about 5 percent and work up or down from there as needed. I have no experience with Acetone.
My second option of preference was Ethanol.
Of course Ethanol has more undesirable side effects than the aromatics.
Such as: leaning the mixture, being slightly corrosive, attracting and combining with water, among others.
Up to 10 percent "should" cause no issues.
Use with caution however regarding the leaning effects which can melt expensive things in the engine!
I don't recommend methanol as it is far more aggressive in attacking the fuel system components as compared to ethanol.
The benzenes, propaline oxide, analine oil, and tetraethylead are all quite hazardous to humans, and are generally not recommended for anyone not accustomed to handling of such substances.
I must admit that I am not a chemist by a long shot.
What I post is simply from my hands on experiences.
My 2 cents for what its worth.
I hope this is helpful.
Good Day Sir.
Rickey.
