Review: It even works on old gas to bring it back to life! - Poured 4oz in a 97k mile MZR 2.3l DI turbo "parts car" tank that was 1/4 full and had been parked from what the previous owner had said "years" so guessing 3 years minimum by the blackberry bramble, water level in the trunk and paint condition. Let it slosh around for the 2 hr trailer ride home, then after a health check reluctantly tried to fire it up thinking the gas had to be as bad as the paint and mold condition. I was blown away when it fired up first crank, and even idled down no issues. It's possible the PO had put some gas treatment in it prior to "it just stopped running" (when it was only a bad battery) but I didn't find any clues amognst the mold. I give it all to Star Tron and their Enzyme Fuel Treatment. My father used it in all of our boats and never had any issues with water during storage in the PNW. I swear by this stuff now for any project car in the future and to clean up the e15 that is now in all the pumps. Review: Very Good. - As good or better than Sta-Bil. Treats more gallons. Has never let me down on my boats winter gas. ## Features - UNLEASH YOUR ENGINE'S FULL POTENTIAL - Star Tron Enzyme Fuel Treatment uses advanced enzyme technology to ensure all engines start easily and run smoothly, even after months of inactivity. - ADDRESS ETHANOL-RELATED PROBLEMS - Helps prevent and cure most ethanol-related issues, including poor performance, rough idling, and decreased fuel economy, supporting improved engine operation when used as directed. - MAXIMIZE FUEL ECONOMY - By removing and preventing gum, carbon deposits, and varnish build-up, Star Tron keeps your fuel delivery system clean, resulting in improved fuel economy. - WORKS FOR ALL ENGINES AND FUEL TYPES - Whether you have a car, boat, RV, or lawn mower, Star Tron works in all engines and all fuels, making it the ideal fuel treatment and stabilizer for any vehicle. - PREVENT WATER BUILD-UP - Helps prevent phase separation by dispersing water throughout fuel as submicron-sized droplets that are safely eliminated while the engine operates, keeping your engine running smoothly in humid or wet conditions. - REVITALIZE OLD FUEL - Star Tron stabilizes fuel for up to 2 years and can help rejuvenate old, sub-spec fuel. - SUPPORT CLEANER FUEL SYSTEMS - Helps maintain cleaner fuel systems to support optimal combustion and engine performance. - COST-EFFECTIVE SOLUTION - At just one fluid ounce per six gallons of fuel, Star Tron Fuel Treatment provides an economical way to optimize engine performance and efficiency. - TOP SELLING FUEL ADDITIVE - Star Tron is a top-selling and highly rated gasoline treatment trusted by thousands of customers to enhance engine performance and prevent ethanol fuel problems. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00EXIVUMM | | Best Sellers Rank | #2,033 in Automotive ( See Top 100 in Automotive ) #6 in Fuel Additives | | Brand | STAR BRITE | | Customer Reviews | 4.7 4.7 out of 5 stars (3,302) | | Date First Available | August 26, 2013 | | Item Weight | 8.5 ounces | | Item model number | 14308 | | Manufacturer | Star brite | | Manufacturer Part Number | 14308SS | | Model | Star Tron Enzyme Fuel Treatment - Classic Gas Formula | | Product Dimensions | 2 x 3 x 7.25 inches | ## Images ![Star Tron Enzyme Fuel Treatment - Gas, Stabilizes Old Gasoline - Image 1](https://m.media-amazon.com/images/I/71mRy89ppjL.jpg) ![Star Tron Enzyme Fuel Treatment - Gas, Stabilizes Old Gasoline - Image 2](https://m.media-amazon.com/images/I/81Zs+GIiEtL.jpg) ![Star Tron Enzyme Fuel Treatment - Gas, Stabilizes Old Gasoline - Image 3](https://m.media-amazon.com/images/I/81NqT0icUvL.jpg) ![Star Tron Enzyme Fuel Treatment - Gas, Stabilizes Old Gasoline - Image 4](https://m.media-amazon.com/images/I/810z+6mwZ+L.jpg) ![Star Tron Enzyme Fuel Treatment - Gas, Stabilizes Old Gasoline - Image 5](https://m.media-amazon.com/images/I/81ghepKUh+L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the mixing ratio of this particular product, since I understand there are 2 different strengths. Thanks!** A: There are two different strengths. The more concentrated mixture usually has a silver bar (with varying words) across the center of the label but that's just my observation, not guaranteed. The strength ratio is odd: stronger is 2.66 times normal and is more economical.For THIS product, you should add 1 ounce for every 6 gallons of fuel, stated on the label. The label also states that adding too much is not harmful. **Q: Can you add this to the gas can that may sit unused for months?** A: We’ll you could. However, I would not use any gas that has been stored for several months. I recommend only get what you will use in a couple of months and not store unused gas for several months **Q: Should you pour it into a tank with fuel in it? I know ideally you should use it before a fill-up but if my car is sitting with gas in the tank, will** A: Depends on the configuration of your gas tank and the fuel filler neck. If it makes a lot of turns all the product might not reach the tank and would be suspended in the filler neck. In the situation you describe I would mix the Star Tron in a small 1 or 2 gallon container with gas and pour the entire contents into your tank. **Q: Is this unit easy to use?** A: Yes it is easy. Follow the directions. Pour a measured amount into the amount of gasoline. The measurements are on the side of the star tron container ## Customer Reviews ### ⭐⭐⭐⭐⭐ It even works on old gas to bring it back to life! *by F***N on June 26, 2026* Poured 4oz in a 97k mile MZR 2.3l DI turbo "parts car" tank that was 1/4 full and had been parked from what the previous owner had said "years" so guessing 3 years minimum by the blackberry bramble, water level in the trunk and paint condition.
