The isopropanol is what would concern me. It will react with various metals along the fuel system and engine. In small % quantities the isopropanol would take the water out of your fuel system is whats in gas dryers like Heet and stuff. And it is probably a one time deal every once in a while in the tank and not tank after tank clear full like you would have if you bought this mixture.
Lots and lots of confusion out there about the grain and petro alcohols. Ethanol doesnt destroy rubber parts. Theres no magic grade rubber out there. Rubber is rubber. I know lots of people running E85 in older Mopar Muscle cars. You have to decide to run E85 all the time and jet things up to get them to run good.
If you have a race car running alcohol (methanol) and you put that alcohol fuel into a street vehicle it will corrode and eat things up.
If it was me I would not fill a tank clear up with this mixture. Maybe a gallon or 2 mixed into a tankful. I would think it would be more of a pain to deal with this mixture then what you will get out of it running the engine. I bet it would be near impossible to get it to start on that stuff in the winter.
