STA-BIL 360 Marine Fuel System Treatment, 32 oz

Very good product, especially for ethanol gas that absorbs water, upon sitting, from the air. This stuff added at about 5 oz. Per 5gal can stops free water from falling out and plugging carbs and filters. Cheap insurance. Saves multiple filter changes and engine troubles. I don’t go boating without using it.

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.

Put in the boat for some over-winter protection from moisture in the gas tank. We'll see how well it works if the boat starts first try next spring. Haven't had any issues in the past. Very easy to use.. large size allows treatment of larger gas tanks. Good two years from the original open.

I use this stuff in all my small engines, outboard engines, and my play car. Its good for any low usage engine. Much less expensive on Amazon than at my local stores.

Seems to work well

this is a great was to order this product and at 1/2 the price - lasts all summer

Essential additive for marine engines. Especially the old carbureted motors. Ethanol can play havoc in carburetors and fuel systems. I've always used stabil marine since I started buying my own outboards . I've used it religiously in every outboard I've owned since I found it. I haven't had a fuel related problem since I started using it. I never bought ethanol free fuel , I just used Stabil marine. No carburetor problems. No hard starts. I actually believe it ties up the ethanol. In the fall, I run the fuel system dry and refill in the spring with fresh fuel treated with Stabil Marine. Never a problem.

Great for keeping gas from spreading when you mix gas and oil

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

Excelente producto. Realmente cumple su función de mantener el combustible libre de humedad y en buen estado durante muchos meses Además, el envío hasta la puerta de mi casa fue excelente.

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.

Works well.
