I know topic has been covered before but I was hoping to find some level of scientific, or at least something greater than anecdotal, evidence on which product is better for long term gasoline (E-10, realistically) preservation.
I have used both before with fine results but I have some "stuff" from my motorcycle to some outboard and even OPE engines which seem very rare use. Certain things like the chainsaw and the motorcycle I like to keep with a full tank for various reasons (ie: chainsaw "grab and go" and motorcycle to prevent tank rust). Currently using marine stabil, but have used the red stabil as well as seafoam in the past for up to a full year with no issues.
Does anybody have real information and which offers the best fuel preservation? I guess its two fold; which one keeps fuel fresh and effective longer? Which one prevents gumming and varnish even after the gasoline is past its effective lifespan?
