A fuel stabilizer is a product that can be of great advantage if you are a boat owner or if you don’t drive your vehicle that often. It can stop the gasoline that is in the tank from degrading by preventing oxidation and breakdown.
You don’t need to be an expert to figure out how a fuel stabilizer works. Once you buy the product, it all comes down to pouring it into the tank and letting the engine run for a couple of minutes to ensure even distribution.
On the other hand, choosing the right one can be tricky, which is why we did the research for you and came up with a list of the best fuel stabilizers. Let’s take a look at what they have to offer so you can make an educated purchasing decision that meets your needs and preferences.

STA-BIL 360 Marine Ethanol Treatment and Fuel Stabilizer
When it comes to brands that can provide efficient fuel stabilizers for an affordable price, STA-BIL is one of the best. This particular product comes in a bottle that holds 32 fluid ounces of this agent, and it can treat up to 320 gallons of fuel. For anyone who wants to ensure better in-season performance, it is definitely one to be considered!
This fuel stabilizer is made in the United States and is a product that can be used for your vehicle or boat. As mentioned above, it is incredibly efficient. With just one fluid ounce, you can clean and prevent degradation of up to 10 gallons of fuel.
The main advantage that you will be looking at is that your engine will be running smoother, leaner, and cleaner. The fact that it doesn’t contain any alcohol makes it an even better choice when it comes to water removal and corrosion prevention.
It can keep gasoline fresh for up to 12 months, which is especially important when it comes to jet skis and boats that you can enjoy only during the spring and summer seasons. Apart from increasing power, it also provides a protective layer for all metal parts, thus ensuring that ethanol-based fuels won’t cause damage.
Keep in mind that this product isn’t something that you should use if you are looking for phase stage separation. Other than that, it is of fantastic quality, is efficient for all types of fuel, and comes at a great price!

There are several points to this product that make it such a great choice. First, you can use it no matter the fuel type (including ethanol-based), and it is suitable for both 2-cycle and 4-cycle engines. Much like STA-BIL, it comes from a well-recognized brand.
It is great for preventing gasoline breakdown, and the fact that it is so simple to use makes it just the perfect choice for boating enthusiasts. On the other hand, you have to keep in mind that it is not as concentrated as the aforementioned product.
Still, that is to be expected given the much lower price it comes at. Most importantly, it doesn’t include any alcohol. It is not only good for preventing corrosion but also for ensuring that the gasoline you are using provides a more powerful engine performance. Overall, it is a worthy choice that you should definitely consider.

Sea Foam SF-16 Motor Treatment
Moving on with our list of the best fuel stabilizers, this Sea Foam product can be considered a superb choice if you are looking for an engine cleaner. Coming in a 16-ounce bottle. It is ideal for gas and diesel motor treatments, so this EPA-registered agent is one that you shouldn’t miss out on.
First and foremost, you should know that this fuel stabilizer can be used for several different purposes. You can clean passageways, injectors, and carb jets with it. Not only that, but it is also perfect for cleaning and lubricating valves and cylinders in your boat.
Apart from corrosion prevention and water removal, it has efficient properties that work to dissolve any fuel residue and oil deposits. You won’t have to worry about metal parts in your motor being damaged by the fuel, which is one of the main reasons why we consider it to be such a good choice.
It is made out of 100% pure petroleum. With this in mind, there isn’t much that we can say against it, apart from the fact that the product smells a bit funny. Still, given its price and reliability, the SF-16 is among the best.

Star Tron Enzyme Fuel Treatment
If you are looking for a super-concentrated formula that can cure any ethanol-based problem and that maintains the freshness of fuel in 2-cycle and 4-cycle engines, you are in the right place. Although this product is made in China, the quality of it shouldn’t be doubted.
Similar to the STA-BIL option, this product comes in a canister of 32 fluid ounces. However, you shouldn’t be fooled by the fact that it is a somewhat smaller package. With this container, you can clean up to 512 gallons of gasoline!
This is a multi-purpose additive that you can rely on when it comes to ensuring that an engine runs smoothly even if it has been inactive for months or if you are using a fuel that is based on ethanol. Along with minimizing the chance of corrosion and damage, it also goes a long way in terms of removing any excess water and gas residue.
This formula can treat up to 16 gallons of fuel with just 1 fluid ounce of the agent. The only thing that you should be cautious about is to follow the instructions and make sure not to overdose your engine with it, given how concentrated the formula is.
Overall, this is an affordable and powerful cleaner that will do wonders to your boat, jet ski, or car!

Quicksilver Quickstor Fuel Stabilizer
At the end of our list is a product that is made for all grades of gas and ethanol blends. Coming in a 12-ounce bottle, it is an affordable and efficient additive that is going to stabilize the quality of your fuel for up to 24 months.
The main use for a product such as a fuel stabilizer is to prepare your boat for active use after a couple of months of staying idle. By pouring the appropriate dose of Quickstor Stabilizer in the engine a few hours before you decide to take it to your garage to be stored for some time, you will be ensuring that it stays at the same quality.
This stabilizer is quite concentrated and can treat up to 5 gallons of fuel with one ounce of the agent. It prevents breakdown and oxidation and can be used in a carb jet, injector, valve, or vehicle motor.
The fact that it removes residue and minimizes the chance of gum forming will go a long way when it comes to saving money that you would spend on a new canister of fuel (because your old one isn’t good anymore).
The issue that we have with it is that it has a strong smell, but once it is mixed with the fuel, that shouldn’t be a huge issue. It is a reliable and reasonably priced product that we definitely recommend.
- Perfect for any vehicle
- Prevents gum formation
- Eliminates residue and build-up
- Lasts for up to 24 months
- Strong smell when opening
When it comes to which one of the five products mentioned above is the best, it isn’t that simple to determine. Our personal favorite would have to be the STA-BIL 360, given how powerful the formula is. Also, you can efficiently use it no matter the fuel type or ethanol blend.
If you are on a tighter budget but don’t want to miss out on the numerous benefits of using a fuel stabilizer, then we would recommend the Sea Foam SF-16 product that offers fantastic cleansing performance for an affordable price!
