As the summer months approach, many of us are eager to get back to our lawn care routines. However, after a long winter of inactivity, our trusty lawn mowers can sometimes refuse to start, often due to old gas that has broken down over time. This issue is more common than you might think, and it can be frustrating, especially if you’re not familiar with the inner workings of your lawn mower. Fortunately, fixing old gas in a lawn mower is a relatively straightforward process that can be completed with a few simple steps and some basic knowledge. In this article, we will delve into the world of small engine repair, exploring the reasons behind old gas problems and providing a detailed, step-by-step guide on how to fix them.
Understanding the Problem: Why Old Gas Causes Issues
Before we dive into the solution, it’s essential to understand why old gas can cause problems for your lawn mower. Gasoline is a volatile liquid that can break down over time, leading to the formation of varnish, gum, and other deposits. These deposits can clog the fuel system, including the carburetor, fuel lines, and engine cylinders, making it difficult or impossible for the engine to start. Stale gas can also separate into different components, leaving behind a sticky residue that can gum up the works and prevent the engine from running smoothly. Furthermore, old gas can contain moisture, which can lead to corrosion and further damage to the engine and fuel system.
The Effects of Old Gas on Lawn Mowers
The effects of old gas on lawn mowers can be significant, ranging from poor performance to complete engine failure. Some common symptoms of old gas problems include:
Difficulty starting the engine
Rough idling or stumbling
Loss of power or Decreased performance
Increased fuel consumption
Engine knocking or pinging
These symptoms can be frustrating and may require costly repairs if left unchecked. However, by addressing the issue of old gas, you can prevent these problems and keep your lawn mower running smoothly.
Prevention is the Best Medicine
Preventing old gas problems is always better than trying to fix them after they’ve occurred. To minimize the risk of old gas causing issues, it’s essential to use fresh, high-quality gas and to store your lawn mower properly during the off-season. Here are a few tips to help you prevent old gas problems:
Store your lawn mower in a dry, well-ventilated area
Use a fuel stabilizer to prevent gas from breaking down
Drain the fuel tank and run the engine dry before storing
Use a gasoline with a high octane rating to minimize the risk of engine knock
By following these simple tips, you can help prevent old gas problems and keep your lawn mower running smoothly.

What are the common signs that my lawn mower’s gas is old and needs to be fixed?
The common signs that your lawn mower’s gas is old and needs to be fixed include difficulty in starting the engine, rough idling, and a decrease in overall performance. Old gas can also cause your lawn mower to stall frequently or not start at all. Additionally, you may notice a decrease in the engine’s power and efficiency, which can make it difficult to cut your lawn effectively. If you notice any of these symptoms, it’s likely that the old gas in your lawn mower is the culprit and needs to be addressed.
To confirm that old gas is the problem, you can try checking the color and consistency of the gas in your lawn mower’s tank. Old gas tends to break down and separate over time, which can cause it to appear cloudy or discolored. If you notice that the gas in your tank has an unusual color or consistency, it’s likely that it’s old and needs to be drained and replaced. It’s also a good idea to check your lawn mower’s manual for any specific recommendations or guidelines for dealing with old gas, as different models may have slightly different procedures for addressing this issue.
How do I drain old gas from my lawn mower’s tank?
Draining old gas from your lawn mower’s tank is a relatively simple process that can be done with a few basic tools. The first step is to locate the gas tank and find the drain plug or valve, which is usually located at the bottom of the tank. Once you’ve found the drain plug or valve, you can use a wrench or pliers to loosen it and allow the old gas to drain out. Be sure to wear protective gloves and eyewear when draining the gas, as it can be hazardous to your skin and eyes. It’s also a good idea to have a container or pan ready to catch the old gas as it drains out.
It’s also important to dispose of the old gas properly, as it can be harmful to the environment if not disposed of correctly. You can take the old gas to a recycling center or an auto parts store that accepts used gasoline for disposal. Once you’ve drained the old gas, you can refill the tank with fresh gasoline and add a fuel stabilizer to help prevent the gas from breaking down over time. It’s also a good idea to check the tank and fuel system for any damage or corrosion that may have occurred as a result of the old gas, and make any necessary repairs before refilling the tank and using the lawn mower again.
What is the best way to stabilize old gas in my lawn mower’s tank?
The best way to stabilize old gas in your lawn mower’s tank is to use a fuel stabilizer, which is a chemical additive that helps to prevent the gas from breaking down over time. Fuel stabilizers can be purchased at most auto parts stores or home improvement centers, and are usually added to the gas tank according to the manufacturer’s instructions. Some popular brands of fuel stabilizers include Sta-Bil and Sea Foam, which can help to extend the life of the gas in your lawn mower’s tank and prevent it from becoming stale or deteriorated.
When using a fuel stabilizer, it’s generally recommended to add it to the gas tank as soon as possible after filling up with fresh gasoline. This can help to prevent the gas from breaking down over time, and ensure that it remains stable and effective for a longer period. It’s also a good idea to follow the manufacturer’s instructions for the fuel stabilizer, as different products may have slightly different recommendations for use. By using a fuel stabilizer, you can help to keep the gas in your lawn mower’s tank fresh and effective, and prevent the problems that can occur when old gas is left to sit for too long.
Can I use old gas in my lawn mower if it’s been mixed with a fuel stabilizer?
While a fuel stabilizer can help to extend the life of the gas in your lawn mower’s tank, it’s not a guarantee that the gas will remain effective indefinitely. Even with a fuel stabilizer, old gas can still break down over time and become less effective, which can cause problems with your lawn mower’s engine and performance. If you’ve added a fuel stabilizer to the gas in your lawn mower’s tank, it’s still important to use the gas within a reasonable timeframe, such as within a few months.
In general, it’s recommended to use the gas in your lawn mower’s tank within 30 to 60 days, even if you’ve added a fuel stabilizer. If you won’t be using your lawn mower for an extended period, it’s usually best to drain the tank and store the mower in a dry, well-ventilated area. This can help to prevent the gas from becoming stale or deteriorated, and reduce the risk of problems with the engine or fuel system. By following these guidelines, you can help to keep your lawn mower running smoothly and effectively, and prevent the problems that can occur when old gas is left to sit for too long.
How can I prevent old gas from becoming a problem in my lawn mower’s tank?
One of the best ways to prevent old gas from becoming a problem in your lawn mower’s tank is to use up the gas within a reasonable timeframe, such as within 30 to 60 days. This can help to prevent the gas from breaking down over time and becoming stale or deteriorated. You can also help to prevent old gas by adding a fuel stabilizer to the tank, which can help to extend the life of the gas and prevent it from becoming less effective.
Another way to prevent old gas from becoming a problem is to keep the gas tank clean and free of debris, which can help to prevent the gas from becoming contaminated or deteriorated. You can also help to prevent old gas by avoiding the use of low-quality or dirty gasoline, which can be more prone to breaking down over time.
