360 Marine Fuel System Treatment, 8 oz 12-Pack

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.

Easy to use and prices right

I've been using the Sta-Bil marine fuel tripment for many years in cars,trucks,boats, riding lawnmower, chain saws and anything that burns gas with no gas issues with gas going bad. 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.

Seems to work well

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.

I ain't gonna bite my tongue when I say that if you have any small engines, outboards or other things gas powered which might be affected by the goo and crap found in almost all gasolines. When you treasure your time and purchases this is a super cheap way to keep your weedeaters, mowers, etc., etc. out of the repair shops. Almost 10 years ago, while living out in the country, I had to replace my generator. I had saved money by not spending a few dollars for fuel treatments. Well I had a rude awakening when a storm hit and my generator was dead from carb' problems. Now I do mean DEAD! Well it was old and after a quite expensive repair bill ready for the next storm. Finally it died the death from another gasoline issue where I had also saved money by no gas treatments. (can we spell stupid?) Here came my new generator and from minute one every drop of gasoline is treated with this product, religiously. At the end of each season or running of my generator now I proceed to run the fuel totally out and then store it "dry". Last week in view of our early hurricane season we again broke out, fueled up and tested Lil' Sparky. Seemingly Lil' Sparky was all ready to go to the races because on the first pull it was once again performing perfectly. Oh, it has been over two years since we last ran Lil' Sparky and as I said "one pull".

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

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.

I've used this product for about years, paying a lot more for it because I've been buying those little squeeze bottles at retail. Now I refill them from the big jug and save big bucks. I use this in all our gas equipment....mainly because it neutralizes the ethanol issues. Also, I notice a significant, satisfying uptick in the fuel mileage of all the cars.
