Thankfully I've now got access to "sober gas" that's VERY convenient but it's only 87, so I still use Stabil in the boat, and keep my fingers crossed on the Carrera. It's freaking amazing the difference in mpg I get in my truck although I've never calculated it. 10 cents more per gallon (less than 3%), and the mpg increase is easily several times that. Hopefully this mandated crap will end soon, as both political parties have contributed to it, and I "think" that awareness (opposition) is growing. It would hurt businesses though...small engine repair businesses
.
ps: for those without access to non-ethanol (and I realize Stabil isn't a cure all)...it's not the use of it that causes harm, it's sitting in the tanks during storage etc. Before "my good" station began carrying it a few months ago, I had began the practice of leaving all my two-cycle engines dry (and I have a bunch - a total PITA) when finished. YMMV...
