I was looking at the ingrediants of Berryman's B-12 Fuel Additive:
2- Butoxethanol (111-76-2)
Mixed Xylenes (1330-20-7)
Methyl Ethyl Ketone (78-93-3)
Curious as to what all that stuff is and what it does?
As it turns out, 2-butoxyethanol is very similar to cellosolve. Commonly used as degreasers (it is the smell you notice in Formula 409), these chemicals will help clean deposits in engines and carburetors, and they have some function as co-solvents, holding alcohol/water/gasoline mixtures together. They can also strip paint and destroy hoses and gaskets, even those formulated for gasoline and alcohols. They are relatively safe at the typical recommended dosage rates, though aggressive additives have been implicated in elastomer failures.
The fallacy is this; yes, it is possible to add enough chemical and soap to the fuel to hold the water in solution, but it takes a lot, not the small doses we are used to seeing in fuel additives. We did test 2 products like this. Typically, the required dose was as much as 20:1 (greater than the 50:1 2-stroke oil dose) and we were VERY uncomfortable adding emulsifiers in such large doses. Unless the additive manufacturer is prepared to run engine durability tests with a manufacturer and get the seal of approval, I think such treatments are risky and unwarranted. The risk to lubrication effectiveness is far too high.
