Small Engines Fail with Ethanol
A Department of Energy study found that gasoline with 15 percent ethanol (E15) caused hotter operating temperatures, erratic running, and engine-part failure on smaller engines. Findings also revealed that gas with only 10 percent ethanol (E10) can help destroy engines.
Ethanol is an alcohol-based fuel made by fermenting and distilling starch crops, such as corn. It can also be made from “cellulosic biomass,” such as trees and grasses. Read more from the article here.
