How to Dispose of Old Lawn Mower Gas

How to Dispose of Old Lawn Mower Gas

Year after year, you faithfully cut your grass with the same old lawn mower. But this year, it’s time for a change. You’ve found a new model that you can’t wait to try out. So what do you do with the old one?

If you’re like most people, you probably just store it in the garage and forget about it. But if your old lawn mower is still running, there’s no need to get rid of it – you can recycle the gas instead.

Let us discuss a few tips on how to dispose of old lawn mower gas properly.

How to Identify Bad Gasoline in your Lawn Mower

Bad gasoline can cause a lot of damage to your lawn mower. It can make the engine run hot, leading to damage or even a fire. It can also cause the carburetor to become clogged, which will make it difficult for the lawn mower to start.

So how can you tell if the gasoline in your lawn mower is bad? Here is what to look for:

  • The gasoline should be a light color, like straw. If it’s darker than that, it might be bad.
  • The gasoline should have a strong odor. If it doesn’t smell very strong, it might be bad.
  • The gasoline should be free of sediment and water. If there’s sediment or water in the tank, it won’t burn entirely and cause problems.
  • If you put the lawn mower out in the sun to get rid of bad gasoline, there shouldn’t be any signs of rust or corrosion on the outside parts of the machine. If you see rust spots, that indicates that the gasoline was bad because it likely contained water, which accelerated the metal corrosion.

The lawn mower should be used regularly. If it’s been stored for a long time and does not run often, that can also indicate bad gasoline because gas will evaporate and clog up the carburetor over time.

It isn’t always easy to identify bad gasoline in your lawn mower. If you’re not sure, consider taking the lawn mower to your local mechanic and asking them to look at it.

If you want other alternatives for disposing of old lawn mower gas, consider trying these tips:

2. Use Bad Gasoline as Weed Killer

Another alternative for disposing of bad gasoline is to use it as a weed killer. Just pour the gasoline onto the weeds and let it soak in.

The weeds will die within a few days, and you won’t have to worry about them taking over your garden. Just make sure to wear gloves and goggles while you do this, and follow all safety precautions.

3. Burning Bad Gasoline

You can burn off bad gasoline by pouring it into the lawn mower’s carburetor and operating the machine until all of the gas is gone. If there are any remaining fuel traces in the engine afterward, just let it sit for ten minutes. The engine should then be clear of any bad gasoline.

4. Leave the Top Off of the Lawn Mower

Or, better yet, remove it altogether. That’s right, just leave the top of your lawn mower off and let the bad fumes evaporate naturally. Just make sure to put it back on before you try to start the engine again.

How to Start an Engine that Has Been Exposed to Bad Gasoline

If you’ve been storing your lawn mower for a long time and the gasoline has gone bad, the engine will likely be difficult to start. Here are a few tips to help you get it going again:

  • Remove the spark plug wire from the spark plug and attach it to the spark plug cap
  • Pour a small amount (1/4 cup) of good gasoline into the fuel tank
  • Turn the lawn mower on its side so that the gas can flow into the carburetor
  • Once the gas has flowed into the carburetor, turn the lawn mower upright and reattach the spark plug wire to the spark plug
  • Turn on the fuel and let it mix for a few seconds before you try starting the mower
  • Add more gas, if necessary, then carefully pull the starter cord to start up your lawn mower

    Hi, I’m Ricky. I’ve been involved in lawn care and landscaping from when I was 15. To be honest, I didn’t like the idea of pushing mowers, collecting grass clippings, and maintaining flowerbeds at the time. But having seem the passion my parents had for gardening and outdoors and the effort they put in maintaining the health and beauty of our landscape, I couldn’t help but not only admire their hard work but also I became a part of it. As someone who loves to spend time with nature’s best, I find myself learning a lot more about gardening and outdoors on a daily basis. Not to mention I love to share the knowledge I’ve gathered over the years with my readers at We Mow Dallas. To be clear, I don’t have a Master’s degree in gardening or anything like that. Everything I’ve learned about gardening, landscaping, and lawn care spring from passion and engagement with my parents. And with a ton of free information out there, plus the ability to run tests and determine what works best for lawn care and landscaping, every day is an opportunity to learn and implement something new. My goal with We Mow Dallas is to teach you exactly how to maintain your lawn and landscape. And since I walk the talk in reality, you shouldn’t hesitate to join me in this wonderful world of landscaping and lawn care.
