Does Non Ethanol Gas Go Bad? (Essential Tips for Woodworkers)
Let’s face it, as woodworkers, loggers, and firewood enthusiasts, we rely on our tools. And those tools often rely on gasoline. But the question that keeps popping up in the back of our minds is: “Does non-ethanol gas go bad?” The answer, in short, is yes, but understanding how and why it goes bad, and more importantly, what we can do about it, is crucial to keeping our chainsaws, log splitters, and other essential equipment running smoothly. I’ve seen firsthand the frustration of a stalled chainsaw in the middle of a big felling job, and I’m here to help you avoid that same headache.
The Shelf Life Saga: Understanding Non-Ethanol Gas Degradation
We all know that gasoline isn’t like fine wine; it doesn’t get better with age. But let’s dive deeper into the specific ways non-ethanol gas degrades and what factors accelerate the process.
Oxidation: The Silent Killer
Oxidation is the primary culprit behind gasoline degradation. When gasoline is exposed to air, it reacts with oxygen, leading to the formation of gums and varnishes. These sticky substances can clog fuel lines, carburetors, and injectors, leading to poor engine performance and starting problems.
- The Science: Gasoline is a complex mixture of hydrocarbons. Oxidation breaks down these hydrocarbons, creating larger, less volatile molecules that form gums and varnishes.
- The Impact:
- Difficulty starting the engine.
- Rough idling.
- Reduced power.
- Increased fuel consumption.
- Potential engine damage.
Evaporation: Losing the Light Stuff
Gasoline is a blend of different hydrocarbons, some of which are more volatile than others. Over time, the lighter, more volatile components evaporate, changing the overall composition of the fuel.
- The Science: The lighter hydrocarbons are responsible for the easy starting and quick acceleration of an engine. As they evaporate, the remaining fuel becomes less volatile and harder to ignite.
- The Impact:
- Hard starting, especially in cold weather.
- Poor engine performance.
- Knocking or pinging.
Water Absorption: A Recipe for Corrosion
While non-ethanol gas doesn’t attract water as readily as ethanol-blended gas, it can still absorb moisture from the air, especially in humid environments.
- The Science: Water in gasoline can lead to corrosion of metal fuel system components, such as fuel tanks, lines, and carburetors. It can also promote the growth of bacteria and fungi, forming sludge that clogs fuel systems.
- The Impact:
- Corrosion of fuel system components.
- Fuel line blockage.
- Carburetor problems.
- Engine damage.
- Fuel tank rust.
Data Points and Statistics
- Shelf Life: Non-ethanol gasoline typically has a shelf life of 3-6 months when stored properly.
- Oxidation Rate: The rate of oxidation doubles for every 20°F (11°C) increase in temperature.
- Evaporation Rate: In an open container, gasoline can lose up to 50% of its volume in just a few weeks due to evaporation.
- Water Absorption: Gasoline can absorb up to 0.01% of its volume in water per month in humid conditions.
Maximizing Your Fuel’s Lifespan: Essential Storage Tips
Okay, so we know gas goes bad. But how do we extend its life and keep our equipment purring? Proper storage is the name of the game.
Choosing the Right Container: Steel vs. Plastic
The container you use to store gasoline plays a crucial role in its longevity.
- Steel Containers: Steel containers are generally preferred for long-term storage because they are less permeable to oxygen and moisture than plastic containers. However, they can rust if not properly coated.
- Pros: Durable, less permeable to oxygen and moisture.
- Cons: Can rust, heavier than plastic.
- Plastic Containers: Plastic containers are lightweight and rust-proof, but they are more permeable to oxygen and moisture.
- Pros: Lightweight, rust-proof, less expensive.
- Cons: More permeable to oxygen and moisture, can degrade over time.
My Experience: I once stored gasoline in an old plastic container that I thought was airtight. After a few months, I noticed the container was bulging, and the fuel had a distinct varnish-like smell. Needless to say, that fuel was unusable. Now, I always use high-quality, properly sealed steel containers for long-term storage.
Sealing the Deal: Airtight is Key
Ensuring your gasoline container is airtight is essential to prevent oxidation and evaporation.
- Proper Sealing: Make sure the container cap is tightly sealed to prevent air from entering.
- Gasket Condition: Check the gasket on the cap regularly and replace it if it’s cracked or damaged.

Where you store your gasoline can significantly impact its shelf life.
- Cool, Dark Place: Store gasoline in a cool, dark place away from direct sunlight and heat sources.
- Temperature Fluctuations: Avoid storing gasoline in areas with significant temperature fluctuations, as this can promote condensation and water absorption.
- Ventilation: Ensure the storage area is well-ventilated to prevent the buildup of flammable vapors.
Data Points and Statistics:
- Temperature Impact: Storing gasoline at a constant temperature of 60°F (16°C) can extend its shelf life by up to 50% compared to storing it at 80°F (27°C).
- Sunlight Impact: Direct sunlight can increase the rate of oxidation by up to 25%.
Stabilizers to the Rescue: A Proactive Approach
Fuel stabilizers are chemical additives that help prevent gasoline degradation. They work by inhibiting oxidation, preventing gum and varnish formation, and protecting against corrosion.
- How They Work: Fuel stabilizers contain antioxidants that react with oxygen before it can react with the gasoline. They also contain metal deactivators that prevent corrosion.
- When to Use: Add fuel stabilizer to gasoline when you plan to store it for more than a month.
- Dosage: Follow the manufacturer’s instructions for the correct dosage.
- Choosing the Right Stabilizer: Look for a fuel stabilizer specifically designed for gasoline engines. Some stabilizers are also formulated for two-stroke engines.
My Experience: I always add fuel stabilizer to my gasoline when I’m preparing my equipment for winter storage. It’s a small investment that can save you a lot of headaches in the spring.
Identifying Bad Gas: Signs and Symptoms
Even with the best storage practices, gasoline can still go bad. Knowing how to identify bad gas can save you from damaging your equipment.
