When it comes to keeping our engines running smoothly, we all want the best protection, especially if you own a vehicle or equipment that gets stored for long periods or runs on ethanol-blended fuels. Whether you’re a collector car enthusiast, a boat owner, or just someone who likes to keep their lawn mower in top condition, choosing the right fuel stabilizer is essential.
You’ve probably heard of two popular products on the market—Sta-Bil and Sta-Bil 360—but how do you know which one is best for your needs? In this article, I’m going to break down the differences between these two products, so you can make an informed decision about which one to use in your engine. Whether you’re storing a vehicle for months or need ongoing protection during regular use, this guide will help you understand when and why you should choose each product.
Let’s dive in and explore the Sta-Bil and Sta-Bil 360 fuel treatments, and see which one stands out depending on what you need.
What is Sta-Bil?
If you’ve ever had to store a vehicle for an extended period, like a boat, motorcycle, or even a classic car, you know how important it is to keep your fuel in good condition. Over time, gasoline can degrade and lead to the formation of gum, varnish, and corrosion inside your engine’s fuel system. That’s where Sta-Bil comes in.
Sta-Bil Storage Fuel Stabilizer is specifically designed for long-term fuel storage. The main job of this product is to preserve the freshness of your fuel for an extended period, even up to 24 months. If you plan to store your equipment or vehicle for months or even longer, Sta-Bil Storage is a fantastic solution. It works by preventing the build-up of harmful deposits and protecting your engine from rust and corrosion caused by moisture and condensation.
But what if you’re using your equipment more regularly, or you’re concerned about the effects of ethanol on your fuel system? That’s where Sta-Bil 360 comes into play.
What is Sta-Bil 360?
As the name suggests, Sta-Bil 360 is designed for ongoing, year-round protection. This fuel treatment is perfect for engines that are used frequently, where you need to worry about ethanol and moisture build-up on a regular basis. If you’ve ever dealt with the problems caused by ethanol-blended fuels, you know they can attract moisture, leading to corrosion and phase separation, which can wreak havoc on your engine.
Unlike Sta-Bil Storage, which is intended for long-term storage, Sta-Bil 360 is meant to be added with every fill-up. It works by preventing ethanol damage, removing water from the fuel system, and cleaning the fuel system to improve performance. This product uses advanced technology like Polyetheramine (PEA) fuel system cleaners to remove carbon build-up, varnish, and other deposits. This makes it a great choice for anyone looking to maintain the health of their engine all year long.

Maximizing the Effectiveness of Your STA-BIL Products
Now that you’ve chosen the right Sta-Bil product for your needs, it’s important to use it correctly to ensure the best results. Here are some tips to help you get the most out of your fuel stabilizer, no matter which product you’ve selected.
1. Always Add Stabilizer to Fresh Fuel
One of the most important things you can do is to add the stabilizer to fresh fuel. Don’t wait until the fuel is already old or degraded. When you add stabilizer to fresh fuel, you’re giving your engine the best possible protection from the start.
Tip: If you’re storing your vehicle or equipment, it’s best to add the stabilizer before you fill up your tank or storage container. This ensures that the stabilizer is thoroughly mixed with the fuel.
2. Follow the Recommended Treat Rate
Each Sta-Bil product has a recommended treat rate, which tells you how much stabilizer to use per gallon of fuel. It’s important to follow this to get the full benefits of the product.
- For Sta-Bil Storage, the typical treat rate is 1 ounce per 2.5 gallons of fuel.
- For Sta-Bil 360, the treat rate is 1 ounce per 5 gallons of fuel.
While Sta-Bil 360 might seem like a better deal because it treats more fuel per ounce, remember that Sta-Bil Storage is meant for long-term storage, so you’ll only need to treat the fuel once during the storage period.
3. Run Your Engine After Adding the Stabilizer
After adding the stabilizer, it’s a good idea to run your engine for a few minutes. This allows the treated fuel to circulate through the entire fuel system, including the fuel lines, carburetors, and fuel injectors. Running your engine helps ensure that every part of your engine is protected and clean.
4. Fill the Tank for Storage
When preparing your equipment for storage, make sure to fill the fuel tank as much as possible. This minimizes the air space in the tank, which reduces the potential for moisture build-up. Less air means less condensation, which is a major cause of rust and corrosion in your fuel system.
5. Store the Fuel Stabilizer Properly
Like any chemical, fuel stabilizers have a shelf life. After you open the bottle, it’s best to use it within a couple of years. Make sure to store the stabilizer in a cool, dry place with the cap tightly sealed. This will help maintain its effectiveness and ensure that it works when you need it.
Fuel Stabilizers Are Essential for Engine Health
Whether you’re looking to preserve fuel for a long period or protect your engine from the effects of modern ethanol fuels, Sta-Bil products offer a reliable solution. Sta-Bil Storage is great for long-term storage, while Sta-Bil 360 offers year-round protection for engines in regular use.
By using the right product for your needs and following these tips, you can keep your engine in great shape and avoid the frustration of dealing with fuel-related problems down the line. So, next time you’re prepping your equipment for storage or getting ready for a season of use, make sure to reach for the right Sta-Bil product and get the peace of mind that comes with knowing your fuel and engine are protected.
