A buddy told me about OPTI-2 several years ago. Been using it ever since. I do have one question however. Can I store my what’s left in my gas can to use the following year and do I have to run my weed eater dry (drain the carb) when I put it away for the winter? I told several neighbors about OPTI-2 and they love it just as much as I do. Thanks for a great product.
