Re: "dry gas" vs ISOPROPYL Alcohol
isopropyl works better than methyl, but is harder to keep dry and more expensive (withour water in it) so companies use methanol in most dry gas formulations. DON't use the stuff from the grocery store or you're adding a significant amount of water along with it. Kind of defeats the purpose, eh?
Ethanol is also a good dehydrating alcohol for fuels and solubilizes a good bit of water allowing it to be passed through the fuel system and burned. The rub is that it picks up water from the air and at 10% in fuel, especially in a wet marine environment, can pick up enough water over time to phase separate with a viscous lower layer (sludge) that won't redissolve in the etoh / fuel mix. as long as you keep it dry you're golden, water is the enemy here.
