Avoid Ethanol in Small Engines / Outboard Motors
Ethanol has the ability to attract greater amounts of water and "phase separate", or form two separate solutions in the gas tank, usually over a long period of time. According to BoatUS.com, "Fuel stabilizer does not prevent phase separation." The best solution is to use ethanol-free fuel in all small engines.
Boat owners have been plagued by the effects of ethanol fuel since the government mandate to increase the amount of ethanol in the nation’s fuel supply, which not only damages boat engine and fuel systems but can present very real safety concerns.
It will dissolve your rubber hoses, clog up your filters, cause you to make unnecessary repairs and eat up precious camping and fishing time. Do not use ethanol fuel in your off-road vehicles, yard machines or other small engines like chainsaws, weed-eaters or lawn mowers.
