What Ethanol Gas Is Really Doing to Your Engine

🚫 Why You Should NEVER Use Ethanol Gas in Your Handheld Lawn Equipment


You rely on your handheld lawn tools to get the job done—fast, efficient, and without drama. But what if we told you one simple mistake at the gas station could destroy your equipment from the inside out?

At M&D Enterprises, we’ve seen it happen too many times: ruined engines, hard starts, expensive repairs. The silent killer? Ethanol in your fuel.

In this post, we'll explain why ethanol is the #1 enemy of two-stroke engines, how it causes piston scarring and compression loss, and why our ethanol-free premixed fuel is the safest option for your handheld tools.



⚠️ Ethanol and Two-Stroke Engines: A Recipe for Failure

While ethanol may be fine for your car, it's devastating for small engines—especially in two-stroke tools like:

Ethanol attracts water from the atmosphere and breaks down quickly, leading to internal corrosion, gummed-up carburetors, and most critically—engine damage.


🔥 The Real Danger: Piston Scarring and Compression Loss

What most homeowners don’t realize is that ethanol doesn’t just clog up your carb—it burns hotter and drier, which can lead to:

  • 🔧 Piston scarring – Ethanol runs lean, overheating the engine and scuffing piston walls
  • 📉 Loss of compression – Scarred pistons and cylinders reduce power, making the engine hard to start or run at full strength
  • 💸 Premature failure – Replacing a two-stroke engine often costs more than buying a new tool

We've opened up hundreds of engines in our repair shop, and the story's always the same—ethanol-fueled damage leaves its mark. Quite literally.



💡 Think You're Buying Ethanol-Free at the Pump? Think Again.

Even when a gas station advertises “no ethanol” fuel, there’s still a hidden risk: unless they use dedicated fuel lines for ethanol-free gas, you may still be getting ethanol in the first few gallons.

Why? Because residual fuel from previous blends remains in the hose. So unless you're pumping several gallons (and wasting money), your small gas can is still likely to get a mix of ethanol-laced fuel.

💥 It only takes one tank of contaminated gas to damage your engine.



✅ The Safe Solution: M&D's Ethanol-Free Premixed Fuel

At M&D Enterprises, we carry professional-grade premixed fuel that takes all the risk—and guesswork—out of the equation.

💬 Final Thoughts: Don’t Let Bad Gas Cost You a Good Tool

Using gas with ethanol in your two-stroke equipment is like pouring sugar in your gas tank—it may not break it instantly, but the damage adds up fast.
