Star Tron Enzyme Fuel Treatment - Small Engine Formula - 16 Oz Treats up to 96 Gals, Gas Additive Rejuvenates & Stabilizes Old Gasoline, Cures & Prevents Ethanol Problems, Improves MPG (014316)

I am a Journeyman Technician for General Motors. I use Startron on my GMC Sierra SLT and Buick Verano. It keeps fuel system clean and works quite well. I also use it in my lawn mower , snow blower and tractor. I used it when in Kalifornia as their gasoline is terrible on vehicles due to their special (clean air) blends which are terrible on fuel system especially in tank fuel pumps and fuel injectors. Rest of the US States the fuel is much better but still could use a little lubricant and detergent to keep thos fuel pumps and injectors working to keep vehicle running and if the parts are clean you get better mileage as well as longevity.

This stuff works great in my older muscle car. Price is good and delivery makes me happy…

i like it... no fuel problems any longer

I am using it in an older Generac 7000W generator. I only put 2 treatments in the gas so it's hard to tell any difference. The generator does run pretty smooth, but it ran like that before I added anything. At this point I hope it's doing all the good things it's suppose to be doing. That's why I only gave it 4 stars. Time will tell.

Been using this for years with great results,If you cant find or buy expensive NON ethanol fuel this is a great alternative.Most of the boaters use this since they usually sit most of the time.A cap full in a full tank of my off season small engine equipment(mowers/saws/weedwackers/etc) lets them start up when back in season with no issues.I believe its better than Stabil IMO

Before I knew that ethanol fuel was/is the worst thing you can put in a small engine or outboard motor, I had to have the carburetor on my Yamaha 4 wheeler completely vatted and rebuilt because of the terrible residue left from ethanol fuel. My mechanic told me to use 100% gasoline and NO ethanol along with a dose of Startron from now on. Sometimes it sits for months before hunting season and since I started to use Startron, the fuel smells just as fresh as the day I bought it and the engine runs like it is new again. I use it in ALL my power equipment and my Evinrude outboard as well. Well worth the price, buy it!

keeps gas good

A little goes a long way in saving any gasoline engine that sits for any period of time with gas in the system, cats, boats , lawn mowers etc . This stuff works great for keeping the gas from going bad and gumming up the fuel system . Works as advertised
