STA-BIL Marine Fuel System Treatment | Full Fuel System Cleaner, Injector Cleaner | Additive for Boats & Watercrafts, In-Season Cleaning & Protection 8oz (12 Pack)

The gasoline they sell in stations now is AWFUL. Ethanol gas is the worst thing they could have come up with. For small engines, like lawn mowers, weed wackers, and especially snow blowers, ethanol gas turns to shellac and gums up the carburetor before you get a chance to use it all. I prepared my snow blower for winter in November; had it running perfectly. By January it wouldn't even start. This marine-grade Sta-Bil is made for ethanol gas, and keeps it from destroying your engine. Gas will last a few months, at best, so I threw out my 5 gallon gas can and only buy a gallon at a time. There are a couple other products that supposedly do the same thing that Sta-Bil 360 does, but I haven't tried them. This works so I stick with it. I even use it in my car because I don't drive that much anymore, and this garbage gas really gums up the injectors too. Cheap enough to use in any gas engine that uses consumer gasoline. You need this.

I run a fleet of outboard powered charter boats. Ethanol problems are something we can't have and the humidity and severe weather changes here in the southeast US wreaks havoc on tanks and fuel. Stabil 360 does what it says.. Period. Many people don't realize the actual engine benefits of 360. Remember, this not only fights phase separation in ethanol fuel, conditions the fuel system to prevent corrosion, but it's also an engine decarb.. This stuff smells nearly identical to Yamaha ring free in the bottle and when it burns through my outboard engines. Saves us all the fuel system storage worries while cleaning my engines fuel system, injectors, vst tank and fuel rails.. My Yamahas run great on 360 stabil. For the money, there's no product by FAR that can touch this stuff. Easy 5 stars from me and my guys!

This stuff works wonders for my small engines. Who decided it was a good idea to use our food source as a fuel? Ethanol has been the biggest scam the American government has ever forced on its citizens.

I buy this fuel treatment for my boat fuel tank. I use it every time I add fuel.. 1oz to 10 gallons of fuel. I have an older 2 stroke outboard... so far no fuel issues.I want to clarify a misconception about this product vs the red stabil. This product has more anti-corosive additives than the red product and is also cheaper to use. This 360 product used 1oz to 10 gallons where the red stabil is 1oz to 4 gallons. The price tag seems more, but the marine 360 goes farther. Especially when you have a 125 gallon fuel tank.

I've been using this product for years, and its been good in all my vehicles for a variety of reasons. BUT, my boat with new engine in it died this week. The fuel and water separated, per my 5 star mechanic. I buy gas at a busy marina , and my last fill up was 2 weeks ago. Its' been very humid. You need to have products that include phase separation prevention, which this doesn't, per testing results I researched. I will continue to use, but adjust how, when, and where.

The product may be good, the specs and value are there, but I recommend using caution when pouring it into your gas tank. I have used the other additives, and puncture the albumin seal and pour it in. I did the same on Sta Bill and found out too late that the aluminium seal is not glued very well to the bottle cap. I saw it pour out into my gas tank, just a little to late to stop. There are no problems at this point, but very concerned about potential gas line clogs. I hope my gas filter stops this. I hope the manufacturer changes there method of sealing the bottle with something that does not pour out into your gas tank.

Sta-Bil goes in gas when I fill up my gas cans- it isn't expensive and helps protect equipment, especially things that don't get used every week (or month, or longer). Sta-Bil marine has an ethanol treatment that the regular red version doesn't, and since where I live all gas has ~10% ethanol, this is what I go with. Ethanol absorbs water from the air, more so over time, and that can wreck small engines. Worth it.

My lawn mower is a pain to start as I have to leave it outside. I typically had to disassemble the carburator filter and float every time I used it in the winter before I started using STA-BIL products. STA-BIL 360 and Marine products have eliminated the starting problems completely!!!!! My Craftsman 6.5 self drive Lawnmower is 25 years old and runs better than ever!!!!! Highly recommended for those who have to keep their lawnmower outside.I also use this in my Ninja ZX-9r, my generators, and my 1965 Mustang that rarely sees the road. All start easily even after months of sitting.

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.

This is a great deal for large boats. I put about a full solo cup in each 150gal tank and enough is left to do the boat for another year or two easily.

Good product.
