Is your trusty snowblower refusing to roar to life this winter, leaving you stranded with a driveway full of snow? The most common culprit behind a stubborn snowblower is often stale or contaminated gasoline. Over time, fuel can degrade, absorb moisture, and clog vital engine components, preventing your machine from operating as it should.
Understanding how to safely and effectively remove old gas from your snowblower is a crucial skill for any homeowner. This article will guide you through the process, from identifying the signs of bad fuel to the step-by-step methods for draining your tank, ensuring your snowblower is ready to tackle the harshest winter conditions. We'll cover the necessary tools, safety precautions, and best practices to keep your equipment in prime working order.
Recognizing the Signs of Stale Snowblower Fuel
The first step in addressing old gas is to recognize the symptoms that indicate it's the problem. A snowblower that sputters, runs rough, or simply won't start after a period of inactivity is a strong indicator. You might also notice a distinct, varnish-like smell emanating from the fuel tank or carburetor, a tell-tale sign of fuel degradation.
Visually inspecting the fuel itself can also provide clues. Fresh gasoline is typically clear or has a slight yellowish tint. If the fuel in your tank appears cloudy, discolored (dark brown or even black), or has visible sediment at the bottom, it's likely past its prime. Water contamination can also lead to a milky appearance.
Beyond these visual and olfactory cues, consider the age of the fuel. Gasoline, especially ethanol-blended fuel, has a shelf life. If the fuel has been sitting in the tank for more than a few months, particularly through a warm season, it's a good candidate for removal and replacement. This is especially true if the snowblower was stored without a fuel stabilizer.
Essential Tools and Safety Precautions
Before you begin the process of draining your snowblower, gathering the right tools is paramount for a smooth and safe operation. You will need a clean, approved gasoline container for collecting the old fuel, a siphon pump (either manual bulb or electric), a funnel, and protective gear such as gloves and safety glasses. A shop rag or paper towels will also be useful for any minor spills.
Safety is non-negotiable when dealing with gasoline. Always work in a well-ventilated area, away from any open flames, sparks, or heat sources, as gasoline is highly flammable. Ensure the snowblower's engine is completely cool before you start. Never smoke while handling gasoline, and keep children and pets away from the work area.
Proper disposal of old gasoline is also a critical safety and environmental consideration. Never pour old fuel down a drain, into the soil, or into regular trash. Contact your local waste management facility or an auto parts store for information on hazardous waste disposal sites in your area.
Method 1: Using a Siphon Pump
The most common and straightforward method for removing old gas is by using a siphon pump. Begin by placing your approved gasoline container on the ground, lower than the snowblower's fuel tank. Insert one end of the siphon hose into the fuel tank, ensuring it reaches near the bottom to draw out as much fuel as possible.
Next, insert the other end of the hose into the gasoline container. If you have a manual bulb siphon, squeeze the bulb repeatedly until fuel begins to flow. For electric siphons, follow the manufacturer's instructions to initiate the pumping action. Continue siphoning until the fuel tank is empty or you've removed the desired amount of old fuel.
Once the fuel is transferred, carefully remove the siphon hose, allowing any residual fuel to drip into the container. Securely cap both the fuel tank and the gasoline container. Clean up any minor spills with your shop rag. This method is effective for most snowblower fuel tanks and requires minimal mechanical expertise.
Method 2: Draining via the Carburetor Bowl
An alternative method, particularly useful if your snowblower has a carburetor with a drain screw, is to drain the fuel directly from the carburetor bowl. Locate the carburetor, which is typically a metal or plastic component connected to the engine's intake. You'll see a small bowl at the bottom of the carburetor.
On the bottom of this bowl, you'll usually find a drain screw or a bolt. Place your approved gasoline container and funnel directly beneath this screw. Carefully loosen and remove the drain screw. The old fuel, along with any sediment or water that has accumulated in the bowl, will drain out into your container.
After the fuel has drained, clean the drain screw and the area around the drain hole. Reinstall the drain screw, tightening it snugly but without overtightening, which could damage the threads. This method is excellent for removing the last vestiges of old fuel and any contaminants that may have settled in the carburetor bowl.
Refueling and Preparing for Use
With the old fuel successfully removed, it's time to refuel your snowblower with fresh gasoline. Always use fresh, unleaded gasoline with an octane rating recommended by your snowblower's manufacturer. For most modern snowblowers, this is typically 87 octane. If your snowblower uses a 2-stroke engine, you will need to mix the correct ratio of gasoline and 2-stroke oil as specified in your owner's manual.
When adding fresh fuel, use a clean funnel to prevent debris from entering the tank. Fill the tank to the recommended level, usually indicated by a fill line or the bottom of the filler neck. It's also a good practice to add a fuel stabilizer to the fresh gasoline, especially if you don't anticipate using the entire tank in one season. This will help prevent future fuel degradation.
After refueling, start the engine and let it run for a few minutes. This allows the fresh fuel to circulate through the fuel lines and carburetor, clearing out any remaining traces of old fuel. Listen for smooth operation and check for any leaks. Your snowblower should now be ready to tackle any winter snow event.

Frequently Asked Questions
How often should I drain the gas from my snowblower?
It's recommended to drain the gas from your snowblower at the end of each winter season before storing it for the summer. If you use fuel stabilizer, you can often leave fresh fuel in the tank, but draining is still the safest bet for long-term storage. If the snowblower has been sitting for more than 3-4 months with untreated fuel, it's a good idea to drain and replace it.
Can I mix old gas with new gas?
It's generally not advisable to mix old, degraded gasoline with fresh fuel. The contaminants and water in the old fuel can still negatively impact your engine's performance, even when diluted. It's best to completely remove the old fuel and start with a clean tank of fresh gasoline.
What kind of gas should I use in my snowblower?
Most modern snowblowers use fresh, unleaded gasoline with an octane rating of 87. Always consult your snowblower's owner's manual for the specific fuel recommendations. If your snowblower has a 2-stroke engine, you will need to use a pre-mixed fuel or mix unleaded gasoline with the correct type and ratio of 2-stroke oil as specified by the manufacturer.
How do I dispose of old gasoline properly?
Proper disposal of old gasoline is crucial for environmental safety. Never pour it down drains, into the ground, or in your regular trash. Contact your local municipality's waste management department or search online for "hazardous waste disposal near me." Many auto parts stores and local recycling centers also accept used gasoline for proper disposal.
My snowblower still won't start after draining the gas. What else could be wrong?
If draining the fuel doesn't resolve the starting issue, other common problems could include a clogged spark plug, a dirty air filter, a clogged fuel filter, or issues with the carburetor itself. Inspecting and cleaning or replacing these components, or seeking professional service, may be necessary.
Conclusion
Safely removing old gasoline from your snowblower is a vital maintenance task that ensures reliable performance when you need it most. By recognizing the signs of stale fuel, employing proper safety precautions, and utilizing effective draining methods like siphoning or carburetor bowl drainage, you can keep your snowblower in optimal condition. Refueling with fresh, appropriate gasoline and considering a fuel stabilizer will further protect your investment and guarantee a smooth start to your winter snow-clearing duties.
Don't let old fuel leave you out in the cold. Take the time to perform this essential maintenance, and your snowblower will be ready to power through any snowstorm. If you're unsure about any step or encounter persistent issues, don't hesitate to consult your snowblower's owner's manual or seek assistance from a qualified small engine mechanic.
