I happen to have 10 spare gallons of 99% anhydrous isopropyl alcohol with no particular use. I'm wondering if I should use this as a fuel additive? I know that's all that "Heet" fuel dryer is made out of. Would it be really bad to add more alcohol on top of the 10% ethanol we already get? Could I use as an octane booster? The jeep has been pinging a little on 87 lately...
I remember once I was trying to start my lawnmower on old/wet fuel. It wasn't gonna happen. So I dumped a bottle of 91% rubbing alcohol into the gas tank to soak up the water, but, the engine actually ran great on the mix...probably about 50/50. It just so happens I was going to take the head off and replace the gasket anyway, and when I did, it was REALLY OBVIOUS that the big dose of alcohol had knocked off a lot of built up carbon. I wonder what the max safe ratio would be? Does this stuff eat rubber like ethanol and methanol?
