Has anyone seen the home brew octane booster you can make really cheap? I found it at: www.gnttype.org/techarea/misc/octanebooster.html Has anyone tried any of these brews and does it work? When I was with my truck today, I noticed on air cleaner lid, that it says to use 91 octane or better. I am running 87 unleaded right now, and am not experiencing any knocks or pinging. Would an octane booster improve engine performance, or should I stay away from this stuff? I have the 350 eng. w/Quadracrap carb. and THM 350 auto tranny. When I took air cleaner off today I noticed a brand new Quadrajunk carb. Also the snorkle tube on my air cleaner was not removed and replaced with different one, someone manufactured one with sheet metal, mighty fine job too. Hope I am not considered a pest in these forums, as I am still learning.
He is a good friend, who speaks well of me behind my back.
