I buy this product 4-5 cases per year great fuel additive&price
Startron is a staple in my garage. I originally used a product called Soltron but found that it was licensed to Starbrite as Startron. I used it to treat outboards that had fuel performance. I put some in the fuel water separator and it cleared the issue, saving me a carb tear down. I have been using Startron for about 13 years in my boat, vehicles and lawn equipment without any phase related issues. I have not had a fuel separation issue on my boat with a 210 gallon tank. While working at a Navy marina, I used it successfully on military boats. I've also used the diesel version on a Ford truck with great result. It keeps carb jets and diesel injectors clean and engines running smoothly.
I have used this for several years, has been very good. everybody I have given it to for a try could not believe the results. My son in law just tried it in a chain saw. He said it never started so easy, and run better than it ever has before
