"The first problems encountered with transitioning to E-10 is the loosening of sludge from the fuel tanks. Ethanol is a very effective solvent and it will attack varnish, gum, and resins - the sludge that can build up in fuel tanks. Once cleaned off the fuel tank walls this build-up leads to poor performance and frequently clogged fuel filters and injectors. The enzymes in Star TronŽ will safely break down and disperse this sludge. After a filter change or two the fuel tanks will be clean and you can focus on the next, more serious, ethanol related issue."

I just heard about this stuff today. I am concerned about E10 negative effects on mileage and mechanics. Is it worth adding?

Here's one I saw. I'm sure there are many others:

I've never used the stuff, but I just changed your link so it's not active (per forum rules).

 

I have a 2003 Accord and the manual allows up to 10%. Just keep hearing bad things plus less mileage. Everything around me is E10 now.
