I always considered isoprophyl alcohol like "rubbing alcohol" a step in the wrong direction since, if you read the label, it can already contain from 30% to 50 % water.
I recommend NO additives for our low compression engines and non-alcohol added gasoline.
The kerosene works against the octane booster.
keep the tank full-buy your fuel where a lot of GOOD brand fuel is being sold-run it enough to keep the fuel fresh.
Maybe a little Nitrotoluene???
