360 Marine Fuel System Treatment, 32 oz

Got the sputter out of mower 2nd cut!! Good stuff.

I use it on all my vehicles, Boots mileage and performance. Corrects the problems caused by ethanol. More Noticeable when I used it on an Older Porsche and My Audi. I have 2 Chevy Astro vans that run better with this boosting the fuel. The Gallon is the best value, but you need 2 drivers to use it up before it loses shelf life from opening. The Quart is working good for just me. Keeps injectors cleans, spark plugs run cleaner. Keeps my Honda Mower starting good, even sitting through the winter. But I store it with a full tank.

This STA-BIL 360 Marine Ethanol Treatment works wonders for my boat's engine, providing top-notch care like a spa day. It's truly a game-changer, maintaining a clean fuel system and enhancing performance as a fuel injector cleaner. Additionally, it effectively eliminates water from the fuel and safeguards the entire system. Boasting the capacity to treat 320 gallons, this 32 fl. oz. bottle packs a punch. I always make sure to use it before hitting the water. A must-have recommendation for fellow boat owners seeking peak engine efficiency! 🌊👍

I've been using Sta-bil for years in my lawn equipment and vintage bikes. Simple to use. I about 1/4oz for 2-2.5 gallons and 1/2oz for 4-5 gallon tanks typical on motorcycles. I do the same for gas cans for the mower, weed wacker, chainsaw, etc. Might be slightly over by a slight amount but it won't hurt anything. Just keep it in all this stuff year round and it'll always start at the beginning of the season. Ethanol is blamed a lot, but the real problem is the aromatics in the fuel. They've been removed in recent years so fuel goes bad in as little as 3 weeks in these puny carburetor bowls. I've been using this with 10% 87 for over a decade, never an issue. Running the carbs dry at the end of the season is not enough. There's still some residue in those tiny idle passageways so you really want to have the fuel stabilizer in there at all times so you don't have to clean carbs every year. The 32oz bottle is a good value if you have a lot of equipment like me and keep it topped off all the time.

Great marine sta-bil,just wish it had the pre measurements built in

Do your research and you'll likely find that STA-BIL makes the best fuel stabilizer. I've been using the blue and red formulations in power equipment and marine engines for decades. Never an issue in the Spring time with last Fall or Summer's gas. Combine this with Yamaha Ring Free for your boat engines.

if you have a lawn mower, snow blower, weedeater, vehichle that isnt driven very much, a boat , this is a must have in the tank of so called gasoline, it isnt gas any more, it ethanol , corn liquor , nothing ruins a good fuel system like bad gas, with corn in it , that cost way more to fix, than using this ounce of prevention, follow instruction's

If you're looking for a genuinely effective solution to keep your boat or watercraft's engine in top shape, I wanted to quickly recommend STA-BIL Marine Fuel System Treatment. This 32 oz. product is fantastic – it works as a full fuel system and fuel injector cleaner, providing excellent in-season cleaning and crucial protection. It's a reliable fuel additive that helps ensure your engine runs smoothly and reliably, making your time on the water even more enjoyable.

This Sab-Bil product is like having your own personal Mechanic. I have been using Sta-Bil for such a long time now that it's a must have in my opinion, in fact i find it as important as a life jacket. I park up for 3 months at a time over winter and when i start the engine it Puuurs. I have just fitted a new 250hp Yamaha and this motor will also be looked after with Sta-Bil Marine Ethanol Treatment.

Best stabiliser I have found. Run it in my Bf115 Honda outboard.

Easy to use and economical additive for boat fuel.

A good product, however found this item cheaper locally

It seems not as my fuel separator has no water in it but only time will tell.
