Description

Introducing Star Tron Enzyme Fuel Treatment - the revolutionary fuel additive that will take your engine's performance to the next level. Whether you're using ethanol-blended fuel or ethanol-free gasoline, or if your engine has been sitting idle for months or used every day, Star Tron's unique enzyme technology ensures that your engine will start easily and run smoothly every time. Star Tron is a multifunctional additive that works in all engines and fuels and is more than just a fuel stabilizer for engine storage. Its powerful enzyme technology removes and prevents gum, carbon deposits, and varnish build-up, so you can be sure that your engine will always perform at its best year-round. Star Tron cures and prevents most ethanol problems, so you can enjoy your engine worry-free. Star Tron also helps prevent phase separation by dispersing water throughout the fuel as submicron-sized droplets that are safely eliminated while the engine operates. Poor combustion results in wasted fuel, smoke, and exhaust emissions. Star Tron not only improves performance and fuel economy but also reduces smoke and other emissions that are harmful to our health and our environment. Star Tron is ideal for all engines, including cars, trucks, boats (2-cycle & 4-cycle), motorcycles, ATVs, lawn mowers, generators, heavy equipment, snowmobiles, RVs, weed eaters, personal watercraft, and anything else that uses regular gas, ethanol blends, ethanol- free, rec fuel, rec-90, or pre-mix fuels. With Star Tron, you can be confident that your engine will run smoothly and efficiently, no matter the application. So why wait? Get the top ethanol fuel treatment + fuel stabilizer + gasoline stabilizer on the market today. Choose Star Tron Enzyme Fuel Treatment and experience the ultimate engine performance. ADD TO CART now and see the difference for yourself. DIRECTIONS: Using Star Tron Small Engine Formula 143 is easy. Simply add 1 fl. oz. (30 ml) for every 3 gallons (11 L) of gas as an initial dosage, and then add 1 fl. oz. (30 ml) for every 6 gallons (11 L) of gas as a refill. Unlike other stabilizers, Star Tron can be mixed with any other fuel additive without worry. There is no need to know the exact amount of fuel in the tank, or the need for expensive measuring bottles because Star Tron is fuel-based so overdosing is not harmful.

    • Very Critical Review long time user
Color: Blue Size: 8 Fl Oz (Pack of 1)
Back in 2008 I tried this product in what is now the standard E10 or gasoline containing 10% ethanol and was very surprised. My father is a very experienced street or high performance engine builder, tuner, and mechanic with almost 50 years of experience he has always been against adding anything to gasoline or diesel. To my surprise without asking he dumped some of this fuel treatment in my gas tank of my 2007 Harley Davidson. I was so shocked at this sight I didn't know what to say or know what that blue bottle of stuff even was. Dropping the bottle into my saddle bag he told me -Go fill up, go for a ride, read the instructions on the bottle before you fill up. If your mileage is no better or you don't notice anything give me your cost of fuel and food for the whole day I will pay for everything." So I topped my tank to full 3.3 gallons and rode to the coast. Instead of 80 miles from a full 3 gallon tank of gasoline 120 miles from the first dosage I was stunned. This motorcycle has EFI all stock no engine modifications. So I zero my trip meter, add more treatment, fill up my tank, go eat, and back on the road. 125 miles later speeds from in town to freeway I find a gas station and fill up again this motorcycle has never been able to get decent mileage, run this smoothly, and actually perform like this on the ethanol type gasoline easily getting 150 miles on a tank as long as I add this product as the instructions say. Also my Harley Davidson 2000 Softail Standard 88" Twin Cam has a carburetor and this product makes a world of difference used with clear or even 10% ethanol 92 octane gasoline. Ever since that day I have used this product in my motorcycles, vehicles, camp stoves, heaters, mowers, saws, and pressure lanterns. I can honestly say yes It will stabilize fuel for 2 years. True story I left a fuel system stabilized with Startron in a older vehicle with a carburetor with a full tank of gasoline that sat outside in the elements. This vehicle sat with the same gasoline for six years occasionally being started to warm up for 20 minutes to keep the battery up or to be just moved out of the way never leaving the parking area. The gasoline after 6 years sure it had a stale smell yet it was not rotten, carburetor was just fine inside, no crud or gunk in the fuel filters, no gunk or crud in my gas tank, and fuel line no problems. That vehicle didn't get any better or worse mileage on the 6 year old gas or even run funny I didn't expect that from any treatment or this one yet it happened. I personally wouldn't recommend anything over a year or two six no im not proud of yet im grateful this product helped it didn't cause harm. So if you have anything from your Power Equipment, ATV, Generator, Motorcycle, Tractor, your classic car, or anything else that you care about give it a try for storage so your gasoline doesn't turn into a varnished mess. Or better yet use it every fill up and keep everything running. I treat my "white gas" stove fuel with Startron my camp stove warms up faster burning just as clean as ever. I treat kerosene with Startron and wicks in my kerosene heaters don't get contaminated with moisture from storage or normal use keeping them burning clean safe like they are supposed to. This product says on the label exactly what it does and I can honestly say it really works. Cleaner burning fuel will help keep your engine oil cleaner and reduce contamination your engine will last longer. Carbon build up or deposit build up inside your combustion chambers and exhaust system will be reduced. Start with a clean fuel system with this product and it will actually stay clean. You will still have to replace a fuel filter yes your filter traps dust and debris. What I have noticed with fuel filters when I replace them is they are now just normally dirty from dust from the environment no more sticky gums or varnish. Spark plugs last longer is the other benefit of this product. This product does not clean dirty fuel systems yet it will not cause any problems or damage if added to a dirty fuel system from my experience. This is not a tune up in a bottle do not expect that read it closely. Tune your engine as recommended by the manufacturer and run this product. You might not notice any better mileage for the first tank full yet try again when you burn that second tank I am going to say that yes you will notice a difference especially on the highway or Interstate or freeway. Winter weather and summer weather this product works exactly like it says. Money is hard to make, engines are very expensive to repair, keep engines maintained as recommended by manufacturer, and if you use this you will notice that you will have a better experience which is not something that you can place a price on. Have some fun do some of your own tests or experiments with this product and share what it did or did not do for you because I am not the only curious person here. I am sharing my personal experiences with this product to hopefully help other people and hopefully learn more uses for Startron. Thank you for taking the time to read this review. P.S. I will probably add more to this review stay tuned. ... show more

    • good price
Color: Blue Size: 8 Fl Oz (Pack of 1)
I love this stuff! As someone who’s battled ethanol-blended gas turning into a gummy nightmare in my outboard motor and lawn equipment, Star Tron has been a total game-changer. I’ve been using the 8 oz. bottle for years now—treats up to 96 gallons—and it keeps everything starting on the first pull, running smoother than ever, and no more phase separation issues after months of sitting idle. Poured it into a buddy’s chainsaw that was acting up, and he couldn’t believe how effortlessly it fired up and purred along. The peace of mind and performance boost are unreal. If you’re dealing with modern fuels, grab this—your engines will thank you! Highly recommend for boats, mowers, ATVs, you name it. I think the price is great. ... show more

    • My favorite additive for small engines!
Color: Blue Size: 8 Fl Oz (Pack of 1)
I use this in all my 2 stroke and 4 stroke small engines. I fill up my gas cans, and add this Startron at the same time. I use it in my motorcycles, ATV's, Dirt Bikes, Lawnmower, and snowblower. I also put it in my mixed gas. I always use ethanol free gas, but many of my toys don't get used all that often. My ATVs don't get run very often; they are carburated and sit for longs periods of time. This year one of them won't go through a whole tank of gas. In order to NOT have Carb issues I use StarTron. Since using this product with Ethanol free gas I haven't had any issued with carb problems on my machines. All my engines run well too, and I think part of that is from using StarTron. I will start each engine every 6-8 weeks and run it for 15-20 minutes to allow the carb to put some fuel through it. I then turn off the Petcock valve and allow the engine to run out of gas in the carb. Works great for me! I over-treat the gas as it is hard to put the exact amount it. But it says that adding too much won't do any harm. I think this is better than seafoam, or stabil. I had carb issues when using the blue stabil as well as SeaFoam. This StarTron works better in my opinion and experience. Pick up a bottle, you won't be dissapointed! Especially important to do over the winter when the engines are going to be in storage! ... show more

No carb issues with pump gas for small engines. Just one ounce per 5 gallons that saves headaches from gelled ethanol gas.

Last year I bought this product locally at a higher cost and used it on a car I stored for 7 months. The gas seemed fresh when I put the car back in service with no white smoke form the tail pipe. Then I could not find it again locally so I was very happy to find that Amazon sold the product.
