Gasoline is a common fuel used to power our vehicles and machines. However, if you leave gasoline sitting for too long, it can become stale and cause problems for your engine. This is where fuel additives come in!
Fuel additives are chemical compounds that are added to gasoline to improve its performance, stability, and longevity.
When it comes to old gas, the best additive to use is a fuel stabilizer. A fuel stabilizer is designed to prevent gasoline from deteriorating over time by slowing down the oxidation process. This helps to keep the gas fresh and usable for longer periods of time.
When choosing a fuel stabilizer, it’s important to pay attention to the type of engine you have and the type of gas you’ll be using it with.
Some fuel stabilizers are designed specifically for small engines, while others are better suited for larger engines. Additionally, some fuel stabilizers are formulated for use with ethanol-blended gasoline, while others are not.
We spent hours researching and testing various fuel stabilizers to identify the best one for old gas.
