How to Winterize & Store Equipment- What Most People DONT KNOW

What happens here

It's crucial to understand that typical gasoline purchased from a gas station, especially E10 (ethanol-blended), has a very short shelf life—as little as 30 days from manufacturing. Non-ethanol blended fuel lasts slightly longer, approximately 90 days from manufacturing. By the time it reaches your equipment, its usable life is significantly shorter. Therefore, storing fuel for the season without treatment will lead to degradation, separation, and potential damage to your engine components. A fuel stabilizer is almost mandatory for any long-term storage.

Goal: Recognize the importance of fuel stabilization due to short fuel shelf life.

All right, guys. I've got Matt. He's the head of the engineering department for both Stable Bill and Gold Eagle fuel products on the line. And we're going to talk about the shelf life of your fuel. After discussing this with Matt, I've just discovered that your typical gas that you get from a gas station has a shelf life of about 30 days max. And that means that's from the time of manufacturing. By the time it gets to the gas station and then gets in your gas tank, it may have already had two weeks on it. Meaning you've got about two weeks of shelf life left on that. Is that right, Matt? Yeah, that's right. The most common fuel you buy in the United States is E10 and has a shelf life of as little as 30 days or it starts to go bad in as little as 30 days. And then some of these guys are going with this non oxy or non-ethanol blended fuel. What can they expect out of that? That can start going bad as little as 90 days. The quality varies depending on where you buy it, but it still does go bad. All right, so you've got 30 days for your standard fuel and 90 days from the date of manufacturing for the non oxy fuel. So that means guys when you're looking at storing your fuel for the year, a fuel stabilizer is almost mandatory, isn't it? Yeah. You got to treat your fuel right, it's it's just proper fuel maintenance and then you won't have problem with your equipment come spring.
