STA-BIL 360 Marine Ethanol Treatment and Fuel Stabilizer - Prevents Corrosion - Helps Clean Fuel System For Improved In-Season Performance - Treats Up To 80 Gallons, 8 fl. oz. (22260)

This is specially made for your ethanol free gas. STA-BIL is a good 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.

I have used Sta-bil for years. The marine lasts longer in the tank than the standard..Great product!

Not much to say from a layperson's point of view. Does this actually work? It seems to - I apply it religiously after each refuel and have not had any fuel issues with my OB motor - a 250 Evinrude e-tec G2. I've got a pretty large gas tank for the boat's size so there's always gas left after a run and even between seasons and again, I've never had a fuel problem - so I suppose it works. It's an ounce of prevention proposition. The bottle is convenient - the squeeze to measure feature with the long neck applicator is handy so you don't need to guess or use an outside measuring container - just squeeze an ounce at a time and pour it into your tank until you hit the desired ratio of stabilizer to fuel. And if you have a gigantic gas tank you can just upend the bottle through the non-metered spout. I'm not sure why it has to be blue. I'm guessing Stabil went with a marine theme but I'd just as well have it clear or as clear as they can make it. If your wax job is not up to snuff and there's a gust of wind while you're pouring (or some jerk doesn't observe the no-wake rule) this stuff will temporarily stain your white gel coat. It seems to bleach away in the sun though, but it takes a while. Otherwise - it seems to do what it's supposed to do and is cheap insurance against the problems that old or water-infiltrated gas can cause.

In the past, I’ve used normal Sta-Bil and it worked well. This winter I’ve decided to try the marine formula.

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.

Great product

This STA-BIL 360 Marine Ethanol Treatment works wonders for my boat's engine, providing top-notch care like a spa day. It's truly a game-changer, maintaining a clean fuel system and enhancing performance as a fuel injector cleaner. Additionally, it effectively eliminates water from the fuel and safeguards the entire system. Boasting the capacity to treat 320 gallons, this 32 fl. oz. bottle packs a punch. I always make sure to use it before hitting the water. A must-have recommendation for fellow boat owners seeking peak engine efficiency! 🌊👍
