STA-BIL 360 Marine Fuel System Treatment, 32 oz | Treats 320 gallons. Cleans fuel systems and injectors, removes water, and helps protect marine engines.

I've been using the Sta-Bil marine fuel tripment for many years in cars,trucks,boats, riding lawnmower, chain saws and anything that burns gas with no gas issues with gas going bad. Great product.

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.

Works as advertised. Needed for ethanol added gasoline.

Easy to use and prices right

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.

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.

a must for todays crappy gas. material is solid, easy to fit in a boat cubby. easy to adjust the levels needed when adding to tanks.

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.

Go’s a Long way in concente

This is an excellent if pricey product, been using it over a year all of my equipment starts and runs much better

Easy to use and economical additive for boat fuel.
