STA-BIL Marine Fuel System Treatment | Full Fuel System Cleaner, Fuel Injector Cleaner | Fuel Additive for Boats & Watercrafts, In-Season Cleaning & Protection 32 Fl. Oz.

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.

Our favorite fuel treatment to use. I add it anytime we use ethanol gas in the boat and for every winter storage. Keeps the fuel good for next time!

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.

Stabil owns the market when it comes to fuel saving additive. I find the marine blue is a much better product than the red.

If you're looking for a genuinely effective solution to keep your boat or watercraft's engine in top shape, I wanted to quickly recommend STA-BIL Marine Fuel System Treatment. This 32 oz. product is fantastic – it works as a full fuel system and fuel injector cleaner, providing excellent in-season cleaning and crucial protection. It's a reliable fuel additive that helps ensure your engine runs smoothly and reliably, making your time on the water even more enjoyable.
