These fuel additive threads are starting to smell like oil threads!
I wish someone would "truly unravel" ( my phrasing for using real scientific knowledge combined with pro level wrenching skills) the question of if and how you treat stored 10% fuel to not cause the problems that -YES!- do actually happen to fuel lines filters,fuel pumps,floats,carb. diaphragms,etc..I live where & how I need a chain saw ready to go all the time & that's just one version of the issue of gas storage aside from the seasonal MC one.
I have now read here & other threads as to how every fuel additive is actually some commonly available "other stuff" such as kerosene,naptha & other various goop. That doesn't mean that "branded cures" don't work but do cost lots more of course.
and take your time answering while I run after some STP...
"If I had my life to live over,I'd dare to make more mistakes next time...I'd relax,I'd limber up.I'd be sillier than this trip, take fewer things seriously, I would take more chances... take more trips...climb more mountains...swim more rivers...eat more ice cream." Jorge Luis Borges, at age 85
