Fresh, unleaded gasoline with an octane rating of 87 or higher – this is the type of gas a snow blower uses for best performance. You should never use gas with more than 10% ethanol in it, as that can damage the engine over time.
I get this question a lot when winter hits. People pull their snow blower out of the shed and stare at the gas can. They want to know what to put in the tank.
Using the wrong fuel can cause big problems. It can lead to hard starts, poor performance, and even engine damage. I’ve seen it happen to friends who didn’t know better.
This guide will walk you through everything about snow blower fuel. We’ll cover the right type, what to avoid, and how to store it properly. Let’s get your machine running right.
What Type of Gas Does a Snow Blower Use? The Simple Answer
Let’s cut right to the chase. Most two-stage and single-stage snow blowers need regular unleaded gasoline. The octane rating should be 87 or higher for good results.
You can find this fuel at any gas station. It’s the same stuff you might put in your car. Just make sure it’s fresh and doesn’t have too much ethanol in it.
Ethanol is a type of alcohol added to gas. It can be bad for small engines. That’s why you need to pay close attention to the fuel mix.
So what type of gas does a snow blower use? The answer is clear. Use fresh, unleaded gas with low ethanol content for a happy engine.
I always check the pump label before I fill my can. I look for the ethanol percentage listed right there. It keeps my snow blower running smooth all season.
Remember this simple rule. Good gas equals easy starts and strong performance. Bad gas leads to headaches and repair bills.
Why Gasoline Choice Matters for Your Snow Blower
Your snow blower’s engine is small but tough. It needs the right fuel to work its best. Using the wrong type can cause many issues.
Old or stale gas is a common problem. It can gum up the carburetor and fuel lines. This makes the engine run rough or not start at all.
High ethanol gas attracts water from the air. This water can then sit in your fuel system. It leads to corrosion and engine damage over time.
Think about when you need your snow blower most. It’s during a big storm when you’re in a hurry. The last thing you want is a machine that won’t start.
Using the correct type of gas for your snow blower prevents these headaches. It’s a small step that makes a big difference. Your future self will thank you during the next blizzard.
I learned this lesson the hard way one winter. My snow blower wouldn’t start during a major storm. The problem was bad gas I’d left in the tank all summer.
The Ethanol Problem in Snow Blower Gas
Ethanol-blended gas is everywhere now. Most pumps sell fuel with 10% ethanol, called E10. This can be okay for cars but tricky for small engines.
The issue is ethanol’s ability to absorb water. Water and gas don’t mix well in your engine. It can cause phase separation where the ethanol and water sink to the bottom.
This watery mix then gets sucked into your engine. It doesn’t burn well and can cause corrosion. Your snow blower might sputter or stall when this happens.
So what type of gas does a snow blower use to avoid this? Look for ethanol-free fuel if you can find it. Many stations now offer this option for small engines.
If ethanol-free isn’t available, use E10 but add a fuel stabilizer. This helps protect the fuel during storage. It’s a good backup plan for winter months.
The Environmental Protection Agency notes ethanol reduces emissions. But for small engines, the trade-offs are real. You need to manage the fuel carefully.
Octane Ratings Explained for Snow Blower Owners
You see those numbers on the gas pump – 87, 89, 91, 93. These are octane ratings that measure fuel stability. Higher numbers mean the fuel resists knocking or pinging.
Most snow blower engines are designed for 87 octane fuel. This is regular unleaded gasoline at most stations. There’s no need to pay extra for premium fuel.
Using higher octane gas won’t hurt your engine. But it also won’t provide any real benefits. You’re just spending more money for no good reason.
The key is consistency. Pick one type of gas and stick with it. Switching between grades can confuse the engine’s tuning over time.
I always use 87 octane in my snow blower. It’s cheap and works perfectly. My machine starts on the first or second pull every time.
Check your owner’s manual for specific recommendations. Some models might suggest a different rating. But 87 is the safe bet for nearly all machines.
Fresh Gas vs. Old Gas: What Your Snow Blower Needs
Gasoline doesn’t last forever. It begins to break down after about 30 days. This process accelerates when the fuel is stored in a small engine.
Old gas loses its volatility, meaning it won’t vaporize as easily. Your engine needs vaporized fuel to start and run properly. Stale gas makes starting much harder.
The breakdown also creates varnish and gum deposits. These can clog your carburetor jets and fuel lines. Cleaning these parts is a messy, time-consuming job.
So what type of gas does a snow blower use? Fresh gas, always. I never use fuel that’s more than a month old in my machine.
During snow season, I buy gas in small quantities. A two-gallon can lasts me several storms. This way the fuel never sits too long in storage.
If you’re storing your snow blower for summer, drain the tank first. Run the engine until it stops from lack of fuel. This prevents old gas problems next winter.
How to Choose the Right Gas for Your Specific Model
Not all snow blowers are exactly the same. Some older models might have different fuel requirements. Always check your owner’s manual first.
Most modern snow blowers use four-stroke engines. These definitely need unleaded gasoline. Never put mixed gas (oil and gas) in a four-stroke engine.
Some very old or very small snow blowers use two-stroke engines. These require a gas-oil mixture. The ratio is usually 50:1 or 40:1 depending on the model.
If you’re unsure, look at the fuel cap or tank. Many manufacturers put stickers there with fuel information. It’s a quick way to check without digging for the manual.
You can also check online. Most brands have PDF manuals available on their websites. A quick search with your model number should find it.
When in doubt, ask at a small engine repair shop. They see all kinds of machines and know the fuel requirements. It’s better to ask than to guess wrong.
Step-by-Step: Fueling Your Snow Blower Correctly
Let’s walk through the right way to add gas. Doing it properly prevents spills and contamination. It also keeps your machine running better.
First, let the engine cool completely if you’ve been using it. Adding gas to a hot engine is a fire risk. I always wait at least 30 minutes after use.
Use a clean funnel with a fine mesh screen. This catches any dirt or debris before it enters the tank. Even small particles can clog the fuel system.
Pour slowly and don’t overfill the tank. Leave about an inch of space at the top. This allows for fuel expansion and prevents overflow.
Wipe up any spills immediately with a rag. Gas on the engine casing can create dangerous fumes. It can also damage paint and plastic parts over time.
Always store your gas can in a cool, dry place. Keep it away from direct sunlight and heat sources. Proper storage keeps the fuel fresh longer.
The Occupational Safety and Health Administration has guidelines for fuel storage. Following them keeps your home and family safe from fire risks.
Common Fuel Mistakes Snow Blower Owners Make
I’ve seen people make the same errors year after year. These mistakes lead to frustrating breakdowns. Let’s go through them so you can avoid the trouble.
Using gas from last season is the biggest error. That fuel has broken down and absorbed water. It will cause starting problems and engine damage.
Another mistake is using fuel with high ethanol content. Remember, E15 (15% ethanol) is becoming more common. This is too much for most small engines.
Some people add diesel or kerosene by accident. These fuels won’t work in a gasoline engine at all. The machine simply won’t start with the wrong fuel type.
Overfilling the tank is another common issue. Fuel expands as it warms up, and overflow can create a mess. It also wastes money and creates fire hazards.
Not using a fuel stabilizer is a mistake for seasonal equipment. If you must store gas in the tank, add stabilizer first. It preserves the fuel for months.
So what type of gas does a snow blower use? Not last year’s gas, not high-ethanol gas, and definitely not diesel. Fresh, proper fuel keeps it running right.
Fuel Additives and Stabilizers: Do You Need Them?
Fuel additives claim to do many things. Some clean your engine, others stabilize fuel for storage. The question is whether they’re worth the money.
For snow blowers, I recommend using a fuel stabilizer. This is especially important if you store gas in the machine over summer. It prevents the fuel from breaking down.
Add the stabilizer to fresh gas before you put it in the tank. Mix it well according to the bottle’s instructions. This ensures even distribution through the fuel.
Some people use fuel system cleaners occasionally. These can help remove deposits from the carburetor and fuel lines. I use one at the start of each season.
Be careful with “octane boosters” or performance additives. Your snow blower doesn’t need more power from the fuel. These products are usually a waste of money.
The Food and Drug Administration doesn’t regulate fuel additives closely. Stick with brands from reputable companies in the small engine world. They understand our equipment needs.
Storing Your Snow Blower with the Right Fuel Strategy
Winter ends, and you need to put your snow blower away. How you handle the fuel affects next season’s performance. Do it wrong, and you’ll have problems.
Option one: drain all the fuel from the tank and carburetor. Run the engine until it stops from lack of gas. This leaves the system dry for storage.
Option two: fill the tank completely with fresh, stabilized gas. This prevents air space where condensation can form. The stabilizer keeps the fuel fresh for months.
I prefer option one for long summer storage. An empty fuel system can’t develop problems. It’s the safest approach for the engine.
Store your snow blower in a dry, covered area. Moisture leads to rust on metal parts. A garage or shed works much better than an open carport.
Before storage, clean the machine thoroughly. Remove any packed snow or ice from the auger and chute. Wipe down the engine and controls with a dry cloth.
Remember what type of gas a snow blower uses next season. It will need fresh fuel, not what’s been sitting all summer. Plan to get new gas when winter returns.
