I want to make some experiment with high octane fuel. But in my county is not posible to get one. We only have RON 95 and RON 98 with 5% etanol
So i decidet to make my own, but need some of your sugestion if someone try this or do some research about this.
First cheap option is mix acetone with fuel.
Acetone is cheap one, it is 60% cheaper than petrol but can't find information how much octane does it have and how hamerful for engine is.
Second option is alcohol. I can get 96% etil alcohol, price is twice expensive than a petrol.
So mixing 96%etil alcohol(113 octane) with RON 98 petrol, in proportion 50/50 I can get about 105 octane
Third option is octane boosters something like this
https://www.merlinmotorsport.co.uk/p/silkolene-pro-boost-octane-improver-oct-bdatasheet say that mixing 1.5% can give 0.5-2 MON, max mixing is 3%
So if I have luck i can get 3-4MON aprox 6-7RON 98+7=105RON
That doesen't give me too much hope,and it is too expensive.
Soo what you say? one thing you must know, I drive car at cruise speed 95% of time, and it runs on LPG. This mixture in tank will be only for experiment and some WOT
1. Acetone(0.5€/L) petrol (1.15€/L) with 20:80 mix at 50L cost about 55€ octane number: uknown?
2. Alcohol (2.5€/L) petrol with 50:50 mix at 50L cost about 90€, octane number : around 105
3. 2L octane booster (40€) with petrol at 50L cost more than a 90€, octane number 101-105
