This article is going to cover two of winter’s great saviors, snow blowers and fuel stabilizers.

They work hand in hand to help you keep your property as snow-free as possible during the cold winter months.

But what exactly is a fuel stabilizer, how does it work and why are fuel stabilizers so vital for your snow blower?

We will answer all of those questions and more in this article…

Why Is Fuel Stabilizer Important For A Snow Blower?

If fuel is left unused in a snow blower it can start to degrade in as little as 30 days. Bad fuel can clog up the fuel system and prevent your snow blower from running properly or, at worst, mean you can’t start it at all. Fuel stabilizers can keep fuel fresh for up to two years, alleviating the problems associated with bad fuel.

What Do Fuel Stabilizers Do?

Fuel stabilizers have been around longer than you might imagine.

Sea Foam was founded in the 1930s and STA-BIL in the 1950s (other brands are available of course).

In recent decades the market has become big business, and fuel stabilizers are particularly important when it comes to snow blowers.

But why exactly?

In short, it can prolong the life of fuel.

If you leave regular fuel (with ethanol in it) in your tank, it can begin to degrade in as little as 30 days.

It is the ethanol in regular fuel that is the main problem, as it attracts and absorbs moisture.

As this moisture is heavier than the fuel it is in, it sinks to the bottom of the tank where it can turn into a varnish-like substance that can block up the fuel system and cause parts to corrode.

The result? When you get your snow blower out for the winter it doesn’t start, or if it does start it doesn’t run properly.

And it is all a result of stale fuel gumming up the carburetor and fuel lines.

Now if only there was something that could prolong the life of your fuel and stop it from going stale so quickly…

This is where fuel stabilizers come in.

A fuel stabilizer will reduce the evaporation rate of the ethanol compounds by bonding with the fuel.

It forms a protective layer over the top of the fuel, that prevents moisture from being absorbed. 

And with no moisture absorbed there is nothing to sink to the bottom of the fuel and block up the fuel system.

Some stabilizers also have detergents that dissolve fuel system deposits entirely.

Fuel stabilizers can keep fuel fresh and effective for up to two years. Much better than it starting to go stale after 30 days right?

Fresh and effective fuel means a snow blower that starts more easily and runs more smoothly.

It is no wonder fuel stabilizers are becoming increasingly popular.

How Do You Use Fuel Stabilizers?

It is pretty simple, add the required amount of stabilizer to the fuel and then run it through the engine for around five minutes to ensure it is thoroughly distributed through the fuel system.

If you are storing gas in an approved can, you can also add stabilizer to that and it will keep the fuel fresh in the same way.

Either way, you want to add the stabilizer to the fuel when it is as fresh as possible. Note that fuel stabilizer isn’t a miracle worker either, adding it to already stale fuel will not turn it good once again!

You certainly don’t need to add much fuel stabilizer to fuel to keep it fresh. Usually a tablespoon or two (which works out at one or two ounces will be fine).

Just follow the instructions provided by the manufacturer and you can’t go wrong.

The role of fuel stabilizers also comes into play when considering whether you should store your snow blower with or without gas when you are done for the season.

I am in the drain your snow blower dry at the end of the season, but many people do like to store their snow blowers for the winter full of gas to keep the fuel system saturated all year round.

If you are a fan of this approach then you will need to stabilize the fuel to keep it good for the next 9 or 10 months.
