Understanding Bad Gas in Lawn Mowers
Bad gas can prevent your lawn mower from operating efficiently. It leads to performance issues and can even damage your mower. Recognizing the causes and signs of bad gas helps you address problems quickly.
Common Causes of Bad Gas
- Age of Gas: Gasoline degrades over time. Typically, gas remains stable for about 30 days. After that, it can start to break down and cause issues.
- Water Contamination: Water can enter the fuel system, reducing combustion efficiency. This often happens when gas sits too long or when storing your mower outdoors.
- Fuel Additives: Some gasoline contains additives that might create deposits over time. These deposits can clog filters or injectors.
- Improper Storage: Storing gas in unsealed containers can lead to evaporation of the more volatile components, leaving behind thicker fuel.
- Difficulty Starting: If your mower struggles to start or won’t start at all, bad gas may be the culprit.
- Rough Idle: A mower that sounds shaky or runs unevenly could indicate fuel problems.
- Stalling: Frequent stalling while mowing can signal that the mower’s engine isn’t receiving the proper mix of fuel and air.
- Unusual Odors: A sour or aged smell can indicate old gas. Fresh gasoline typically has a sweet odor.
Being aware of these factors helps you take proactive measures in maintaining your lawn mower and ensuring a smooth mowing experience.

Step-by-Step Guide on How to Clean Bad Gas Out of a Lawn Mower
Cleaning bad gas from your lawn mower is straightforward. Follow these steps to restore your mower’s performance effectively.
Draining the Old Gas
- Locate the Fuel Tank: Find the fuel tank on your mower and check for the drain plug.
