It’s common for people to fill up their snowblowers as the winter months come around.
This can create a situation where you are ensuring the motor continues to function as required and you don’t have a situation where something breaks down.
A lot of people deal with this because they don’t drain old gas from a snowblower. They let it sit in the machine and that starts to ruin its performance.
This is why it’s important to figure out what to do if you forget to drain gas from the snowblower.
If you forgot to drain the gas from the snowblower, start by letting it run until it stops. If this does not work, add fresh fuel and a fuel stabilizer. This will help alleviate the issues associated with old fuel in the snowblower and get it to work again.
You will need to be diligent while doing this and it is always best to start with the simpler solution of letting it run out.
Here is more on how to drain gas from a snowblower and what to do when there is old gas in the snowblower.

How To Drain Gas From A Snowblower
1. Let The Snowblower Run
You are going to start with a straightforward solution.
If there is old fuel in the snowblower, your best bet is to make sure the snowblower can run. This is going to include letting it motor along for a few hours.
You should not use it during this period or move it around.
Just let it sit in one spot and make sure the fuel runs out.
This is going to ensure the fuel burns out naturally and you are then going to have an empty tank to work with. This will allow you to pour fuel into the snowblower.
This is a good solution because it does not take a lot to do it and you are going to see wonderful results along the way.
For the most part, this should take care of the issue for you.

2. Add Fresh Fuel
Let’s assume running the snowblower until the fuel runs out is not efficient.
What are you going to do then?
You are going to need to think about adding fresh fuel.
This is the best way to help top up the tank and then see if that helps get the snowblower to run efficiently. Sometimes, it might sputter a bit at the beginning but then it is going to pick up again. This is normal.
You just have to be patient and make sure the fresh fuel has time to settle in the tank.
If you do this the right way, the fresh fuel is going to be a good starting point for getting the snowblower to function as you want it to.
3. Add A Fuel Stabilizer
You will want to remove old fuel from a snowblower as soon as possible but that is not always the only solution.
There are fuel stabilizers sold on the open market for situations such as these.
Fuel stabilizers are good at creating a consistent finish for the fuel and that is how you can begin to see better results from the machine.
You will always want to add the right amount of this formulation to get the results you are after.
Read the label and only pour in as much as you need. By mixing it with fresh fuel, you are going to help set up the tank in a way where it will get the snowblower to work efficiently.

4. Re-Test The Snowblower
Now it is time to re-test the snowblower.
You will want to turn on the snowblower and see if it runs as you want it to.
This includes letting it run along a small patch of snow. If it is generating enough power, the snow is going to go flying in the direction you want it to and you are going to see excellent results too.
This is something you should be aiming for when it comes to seeing good results with the snowblower.
Final Thoughts
I forgot to drain gas from the snowblower!
If you forgot to drain gas from the snowblower, it’s best to let it run until the tank is empty. If this does not work, add fresh fuel along with a fuel stabilizer to help get the snowblower to work.
This is how you are going to get it to work as planned.
Snowblowers should not have old fuel in them for more than 30 days. This is why refueling the machine is a must at the start of the winter season.
If you forgot to drain the fuel from a snowblower, it is important to make sure you do not use it right away. Either let it run out or add fresh fuel with a stabilizer to get the results you are after.
