I had a long conversation with the, possibly owner and chemist from Starbrite at a trade show a couple of years ago. Very nice guy, and FWIW local to me. The week following the trade show I went and purchased a bottle of Startron. Small Engine Formula. Learning at the trade show that this worked great in generators and small engines. I mixed as instructed and took my Moms Honda Generator, that had sat for a while but still ran, however it surged. The verbal face to face claims from the manufacturer indicated the engine would run and smoke, while it removed carb deposits and cleaned build up from the intake and combustion area. I was told this would be approximately 30 minutes and the engine would run better as the 30 minutes expired. Fired it up, and yes it smoked a bit, let it run more than 30 minutes. Also, after letting the machine sit, I ran it a second time. For whatever reason, the product did not live up to the claim in my application. I am sure it did absorb any water from the fuel. Without doubt it stabilized the fuel for longer life. In the end the little carb was torn down, properly cleaned, and reassembles with the original seals. Once together it fired right up, and ran like a champ on gasoline with no Startron in it. Five minutes ago, I went to the garage and there on the shelf is 3/4 of the bottle of unused Startron. I won't say it's good, won't say it's bad, just noting it is there for me to try again in another small engine with woes, but I expect similar results.
Mike, you asked specifically about the claim of negating harmful effects of ethanol in gasoline. Taken as a copy and paste from Startrons webpage, I am going to plead the 5th and just quote them. This was also what I learned / was explained at the trade show. Probably one of the products besides the majority product of Naptha, is engineered to grab the ethanol molecule and bind it to the Naptha, nut honestly...I am not sure. The guy is very nice from what I recall. Passionate about his products, and may be worth a phone call to hear it directly.
Small engines are especially susceptible to ethanol problems such as gum deposits that clog carburetors, making engines difficult to start and run rough. Star Tron Enzyme Fuel Treatment cures and prevents ethanol fuel problems by preventing gum formation, stabilizing fuel chemistry and allowing fuel to burn more completely for optimal engine performance and full power. Star Tron can actually clean dirty carburetors and keep them clean, while also stabilizing fuel for up to 2 years and rejuvenating old, substandard fuel. It helps prevent phase separation by dispersing water throughout the fuel as submicon-sized droplets that are safely eliminated while the engine operates.
I know it's not an answer you wanted, but it is my experience with the product. The reading of the MSDS the other night let me know it is a lot of Naptha in a blue bottle...it will raise octane of gasoline, certainly changes the burn or flame speed and makes any comparison really difficult when compared to a heavier unmodified gasoline.
PK[/QUOTE......Paul , are " STARBRITE " and " STARTRON " connected ? ? ?..................and as stated later I only use the Startron for it's claims about " ETHYL " , I don't believe there is anything you can just add to GAS to substitute for dis-mantling and properly cleaning the parts JMHO.......Mike :thumbup:
