Why You Should Not Use Fuel With Ethanol
Protect Your Equipment: Understanding the Effects of Ethanol
Why Does Bad Fuel Damage Engines?
Modern fuels often contain ethanol and bio-diesel, which attract water and lead to issues such as:
- Phase Separation: Water in the fuel separates, forming a corrosive ethanol/water mix.
- Corrosion: Ethanol accelerates rust and decay inside engines.
- Fuel Decay: Ethanol-based fuel degrades faster, leading to gum, varnish, and sludge.
What is Ethanol-Blended Gasoline?
Most gas today, like E10 (10% ethanol), attracts water. This mix settles at the bottom of your tank, creating a corrosive layer that can:
- Damage Plastic and Rubber: Ethanol makes rubber and plastic brittle, especially in older equipment.
- Corrode Engine Parts: Ethanol accelerates rust, especially in humid climates.
Common Ethanol Issues in Small Engines
-
Phase Separation in Two-Stroke Engines
Ethanol separates from gasoline, creating a lower-octane, corrosive mixture. This causes overheating, running issues, and even engine failure. -
Phase Separation in Four-Stroke Engines
Water from rain or humidity can exacerbate corrosion, leaving the carburetor beyond repair. -
Varnished Fuel and Engine Failure
Fuel with ethanol decays in 60 days, leaving varnish that clogs components, damages pistons, and reduces engine performance.
Did You Know?
Ethanol issues are responsible for over 75% of repairs related to starting and running problems in small engines!
How to Protect Your Equipment
- Use Ethanol-Free Fuel: Consider ethanol-free options to avoid phase separation and corrosion.
- Add a Fuel Stabilizer: Use a stabilizer to slow fuel decay and protect your engine.
- Regular Maintenance: Let us test and service your equipment to prevent long-term damage.
