You ought to know that ethanol destroys gasoline for 30 days, but with this fuel stabilizer, it can be stopped.
This formula is a step up from the one that I used for small engines. I’ve been using it for four years to change fuel at every end of the season. Thanks to it, in the winter, water separation caused by ethanol-blended gas is no longer a problem. Aside from keeping the gas clean, my boat engine also has zero carb issues. Hence, long-term storage won’t end up with troubles and conflicts.
You’ll know that it stabilizes fuel excellently because the tank and lines don’t get rusty. The injectors or the entire fuel system don’t corrode as well. It also works for small engines and even eliminates the sound coming from the cylinder ones. So, you don’t have to hesitate to have it on a snowblower, mowing trucks, and other lawn equipment.

6. K-100 K100-G MG Fuel Treatment & Additive
I’ve used many gas fuel additives, but this one simply rocks! When phase separation occurs, water usually goes to the bottom of the gas tank. However, this fuel treatment doesn’t allow it because it breaks the large water particles in the first place. Not all additives can do this trick so I can’t help but be fascinated.
Believe it or not, it activates my 115 HP Mercury outboard boat engine that was idle for two years. I thought I would have to be burdened with more than 20 gallons of old gas and pay for a costly dealership. But I don’t need these procedures that require hundreds of dollars because of this K-100’s wonderful abilities. A single bottle can completely get rid of the old gas. From then on, I use it for my outboard motor.

I call this fuel additive for ethanol gasoline a ‘mechanic in a bottle’. The improvements in boats, vehicles, and equipment are undeniable. Even though it promotes itself as an injector cleaner and fuel conditioner, you’ll be in awe to uncover other results.
It’s made for both gasoline and diesel engines. Even so, it’s a blend of great additives, slick oil, and detergent action to assist the engine for maximum efficiency. Although it increases power, there’s less fuel consumption. The most noteworthy effect of this formula is the acceleration of my boat. I think it increases the horsepower, and the engine runs smoothly at the same time.
The promotion of speed also applies to cars. Although my boat and car age each day, they continue to run like brand new. What the manufacturer says about this product is true. The engine becomes noticeably cleaner than before and this fuel treatment even lubricates its upper end. Since it can clean properly, no unwanted noise can be heard from my car anymore. Start-up issues also disappear.
The highlight of using this formula is dissolving heavy carbon deposits around the cylindrical head and intake valve. Accordingly, I’ve never met any issues caused by ethanol. Most people have mentioned the same thing in Lucas ethanol fuel treatment reviews. You can let it reach inaccessible areas for cleaning.
- With great additives to maximize engine efficiency

Factors To Consider When Choosing Ethanol Fuel Treatments For Boat
Types of ethanol fuel treatment based on additives
Here are some additives that can help a lot in treating ethanol gas:
- Conventional fuel storage – With this gas additive for ethanol, the storage period of the fuel is extended. It can’t happen with regular gasoline, but this additive doesn’t ensure separation.
- Ethanol fuel storage – This additive has the same ability as conventional fuel storage. Nonetheless, it can only deliver limited improvement of E-10 phase stability.
- For restoration – The name is misleading since this doesn’t work for restoration. Instead, it hinders separation and restores separated fuel.
These are different marine fuel additives that quality fuel treatments combine with. You can tell the excellent marine fuel stabilizer vs regular type apart based on their effects.
Benefits of using ethanol fuel treatment
- Can prolong fuel’s lifespan – You don’t need to drain the fuel from your tank when placed in long-term storage. The fuel stabilizer will preserve its quality as time goes by.
- Cutting down emissions – It’s known that smoke, soot, and other emissions are hazardous to humans and the environment. These things can be minimized through a clean fuel system made possible by a fuel stabilizer.
- Lubricates engine parts – Contamination and friction can deteriorate many engine parts such as carburetors and engine lines. A stabilizer can make the engine function smoothly as it can be a form of lubrication.
- Blocks water and moisture – When the engine remains inactive for a long time, water and moisture accumulation is unavoidable. A fuel stabilizer can stop this from happening while minimizing the formation of rust and corrosion.
- Enhancing fuel efficiency – Fuel treatment wipes off emission and enhances combustion for fuel-efficiency. Every drop of fuel is put into good use, and the boat’s mileage increases as well. When the engine runs smoothly, the fuel consumption is minimized without a decrease in power.
Is Ethanol Gas Bad For Boats
Marine engines are designed to handle ethanol gas or E-10 bears 10% ethanol. It’s recognized as a superior marine fuel because it can maintain low levels of water and keep the system dry. However, it’s necessary to treat it if not used within a few weeks. It’s a must if an engine is set aside for winterization or long-term storage.
When the fuel is under storage, it tends to oxidize or become sour. The next thing that happens is absorbing water from condensation. The water capacity held by ethanol turns low when there’s a low temperature.
Thus, phase separation mostly occurs in winter, and it’s known to damage engines and motors, including the ones in boats and crafts. To reverse this, you have to fill your tank with fuel and add a recommended dose of stabilizer.
Does Fuel Stabilizer Prevent Ethanol Damage
Yes, it does. As mentioned, damages on the boat engine are from phase separation. But fuel stabilizers can counter them by prolonging their life span and functions. It also protects against sludge, corrosion, rust, and other contaminants that impede engine performance.
How Much Additive Do I Need To Remove Ethanol From Gas
An excess amount of additives doesn’t pose harm in most cases. But it’s best to follow the recommendation of the manufacturer on the label or product description. If the suggestion is to use an ounce, there’s no difference in the effects if you add more. Always check the recommendation before using; extra additives may bring adverse effects in some cases.
What Is The Most Trusted Ethanol Fuel Treatment For Small Engines
The most trusted ethanol fuel treatments for small engines are STA-BIL, Sea Foam, STAR BRITE, Lucas, B3C, and CRC.
Summary
Your boat engine is the reason why you have a wonderful sailing experience. So, buying the best ethanol fuel treatment for boat is necessary. Spending on this solution saves you from spending more money for repairs of broken engines. It’s a must when your boat engine is placed in winterization or long-term storage. The fuel treatment keeps the fuel fresh while it prohibits damages that are caused by ethanol.
