I poured in a full bottle to a 2/3 full tank (first time using it), I should have read the reviews first! Some reviews say it can gum up spark plugs and the cats and rings! Maybe Ill fill the tank to dilute it or go to a gas station have them siphon out the gas! Anyone use this stuff??

 

Fill the tank up to full with the highest octane you have access to. You should be OK. I don't use octane boost I just use 93 octane (Premium octane in FL). I do use Liqui Moly fuel system treatment at each oil change interval. If I were in your shoes I'd use it or something like it ASAP on that tank of gas as well as the fillup.
