STAR BRITEStar Tron Enzyme Fuel Treatment SEF Gasoline Formula - 1 oz. Treats 6 Gallons - 32 OZ (14332)

This is the best fuel additive I have found over the years. Sta Bil is good too but Starbrite is what the professional boat mechanics use to prevent build up in the boat tanks so it's what I use any time I have gas that will be sticking around a long time. Living in New England, our snowblowers don;t get used year round and there's nothing worse than needing to clean a carburetor in the middle of winter.

Works great

Good quality, decent price.

It's a very good product for my European car. Unfortunately, it arrived with a small leak, even though it was sealed.

We add this to our lawn mowers gas (push and tractor ) for an easy start up in the spring. Upstate NY.

Startron is a great product!!

Helps combat ethanol in gasoline for my antique car

My boat motor starting running rough so I drained 5 gallons of gas from the tank into white 5 gallon plastic container and noticed it was a yellow/orange color and cloudy. I researched and decided to try this. I poured the recommended amount into the gas container and waited a couply days and it looked like normal gas again. I added the recommended amount to my boat gas tank and on my next outing, after a short time (to run the bad gas through the lines), the motor ran fine and have had no problem since. I had been using another gas treatment that I liked but now will be using this and it seems to stablize the fuel better and is said to last longer.
