Ethanol Defense

MSDS only shows percentage of chemicals used in Ethanol Defense by volume. Their formula is proprietary. This has nothing to do with how much you add to you gas tank.

ie... Maximum of 80% magnesium sulfate to 20% fuel oil or
Minimum of 55% magnesium sulfate to 45% fuel oil or anywhere in between, to make up 100% of the bottle they sell.

MSDS is actually an outdated term, the sheets are now called SDS or Safety Data Sheets. OSHA regulations require this information for all chemicals. As a worker you have the right to know what the health issues are with the chemicals you work with and or exposed to. An SDS contains, chemical composition, flammability, volatility, first aid, handling and storage information
 
Here's the SDS for Ethanol Shield sold by Home Depot. We use it + lead additive in our classics + 2 cycle engines. The ethanol destroys the seals in small gas blowers, etc, so some of the rental tool vendors "import" and sell their ethanol free gas on the left coast.

I have used Ethanol Defense, but the price is quite high compared to Stabil, so I use Stabil. I doubt that Ethanol Defense is better than Stabil for counteracting the effects of alcohol gas.
 
Adding some automatic transmission fluid to gas is a good trick to clean up the fuel system and lubricate the valves.
