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 5 out of 5 by good product Been using other stability products for years. Haven't had any problems caused by ethanol in either of my outboards since. June 20, 2016
Rated 5 out of 5 by does what it's supposed to Really happy with the Sta-bil 360 Marine. It seemed to make my boat engine run smoother and it seemed to run leaner. Very pleased...and I'm glad I tried it! May 10, 2016
Rated 5 out of 5 by Trusted Brand This product delivers. Fuel was good after sitting for over a year. May 4, 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. 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 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. April 26, 2016
Rated 5 out of 5 by The Right Tool for the Job!!!! I got this product about a month ago and used it in my 4.3 FI boat that had not been run in 1-1/2 years. I added 5 gal of fresh gas and the Marine Sta-Bil. It fired right up and ran perfect. You just can't beat Sta-Bil products. Marine engines need all the help with fuel freshness due to our 5 month storage through the winter. April 26, 2016
Rated 4 out of 5 by good stuff ! I tried this out an it seems to do a good job in my outboard motor April 26, 2016
