Product Description

As America's #1 Ethanol Treatment, you can trust STA-BIL 360 Marine to keep your gasoline-powered engine running at peak performance, and is safe for use in all gasoline engines, including 2-cycle and 4-cycle. By preventing the buildup of unwanted gum and varnish, this product is recommended for use in your boat, jet ski, and other nautical gasoline-powered equipment. STA-BIL 360 Marine Ethanol Treatment & Fuel Stabilizer prevents corrosion caused by ethanol blended fuel. Effective in all gasoline blends, including ethanol and non-ethanol, this product helps increase engine power and fuel efficiency. STA-BIL 360 Marine is engineered to combat the negative effects of ethanol-blended fuels. This industry-leading formula prevents corrosion, cleans the fuel system, and prevents the buildup of unwanted gum and varnish ensuring your equipment will be ready to go whenever you need it. 1oz treats 5 gallons of gas. If using with small engine equipment pour directly into your gas can. If adding directly to your boat it is best practice to add STA-BIL 360° Marine before adding fresh fuel at the pump. This product is designed to be added to the fuel as soon as you get it that way you know the fuel is fresh. This formula will also keep gas fresh for up to a year. Use throughout the season to ensure smooth sailing year-round!.

    SAME 1oz/10 gallons instructions on rear label; 1oz/5gallons label suggestion removed.  Good for up to 12 months storage.
    5 Stars
    SAME 1oz/10 gallons instructions on rear label; 1oz/5gallons label suggestion removed. Good for up to 12 months storage.
    I (hubby) habitually buy the 32oz Marine Stabil because it makes my car run better than the standard "red" Stabil, and is more economical in this size than in the smaller size (?12oz?). I was a bit concerned when I saw this "360" variant, and wondered if this was just a new label, or a new formulation. My confusion stems from the OLD rear label telling you to use 1oz/5 gallons for storage, while ALSO instructing you to use 1oz/10 gallons for in-season use & everyday performance; but, the manufacturer's description here at Amazon for the new-label 360 Marine Stabil just says 1oz/5 gallons. So, is this a new formulation? Having bought 2 of these 360 Marine Stabils, and now holding them in my hand, it seems Gold Eagle Co. could use some more detail-oriented marketers. The NEW rear label has been updated, and while the online description here (October 2, 2015) says use 1oz/5 gallons and NOTHING about 1oz/10 gallons, the NEW rear label says NOTHING about 1oz/5 gallons, and only says: "USAGE DIRECTIONS: 1 oz (30ml) treats 10 gallons (38L) of fuel. Recommended for use AT EVERY FILL UP in season for year round performance & protection." A bullet point on the rear label says "Stabilizes fuel for up to 12 months." Another bullet point on the rear label says "Treats 320 gallons". While I do treat my mower gas cans with Stabil at 1oz/5 gallons so I never deal with spring varnish in my gas powered mowers/weedeaters, I do use this Marine Stabil at 1oz/10 gallons at every fillup, and get much better car performance and mileage than if I do not use Stabil. So, is the description variance from the old label to the new 360 label from lack of marketing attention or Legal Department fussiness? Dunno. But having used Stabil products for over 30 years, the discrepancy between online description and new rear label certainly is annoying. I'm glad the effective concentration (1oz/10gal) has remained intact because this is an awesome product, and I highly recommend its use.
