                                According to the TruFuel brand, ethanol is a major problem for small engines because it attracts water and degrades parts. This issue is why many turn to engineered fuels like TruFuel, which is a blend of high-octane, ethanol-free gasoline combined with synthetic lubricants and stabilizers designed for optimal outdoor equipment performance.
