Product Details

Sta-Bil® 360°™ Marine™ fuel stabilizer is designed to make your marine engine perform better year-round. Use it at every fill-up to boost engine power and fuel efficiency, and add it to the fuel line before storage to stabilize fuel up to 12 months.
The additive removes excess water from the fuel tank for a smooth idle, and provides effective protection against ethanol blended fuels. It is formulated specifically for marine environments, with extra corrosion preventers and fuel system cleaners to help protect against corrosion from moisture and ethanol-induced water attraction. 360 Marine removes carbon buildup, gum, and varnish to help increase performance, power, and fuel efficiency. The treatment coats all metal parts in the fuel system, above and below the fuel line, to protect from rust and corrosion, even when the engine is not running.

Rated 4.9 out of 5 by 45reviewers.
Rated 5 out of 5 by Use it at every fill up. My boat has over a 50 gallon fuel tank. I get out to use my boat probably 10 times a year. That adds up to a lot of gas just sitting around not being used. Using StaBil, I never have engine startup or performance problems no matter how long it is between uses.

Rated 4 out of 5 by Seems To Work Great It seems to work very well but it's hard to tell with this product because it goes into your fuel tank. I can tell you that I have never had 1 bad product from Stabil and Gold Eagle so I'm sure this one works great too! [This review was collected as part of a promotion.] August 25, 2016

Rated 5 out of 5 by Prevent fuel issues by using Sta-bil 360 - I do I have used Sta-bil fuel products for years in my boat, lawn items, generator and classic car and have never had a fuel issue. A friend mine just started using this Sta-bil 360 for his outboard boat motor gas. He used to have Ethanol issues but after using this additive has no more issues. Using Sta-bil 360 is an automatic no brainer that prevents a lot of frustration and saves money from the problems of bad gas. [This review was collected as part of a promotion.] April 26, 2016
Rated 5 out of 5 by Sta-Bil 360 Marine I've been using Sta-Bil nearly all my life and I've never had any long term storage issues. Always start right up without fail, no matter what the product is: car, boat, lawn mowers, anything [This review was collected as part of a promotion.] April 26, 2016
Rated 5 out of 5 by Easy to use This is easy to measure and use, I keep one bottle on my boat at all times. [This review was collected as part of a promotion.] April 26, 2016
