I seem to recall a product...but I can't seem to find the exact same thing as I believe I remember. There was a Techron fuel system cleaner in a 32 oz bottle, but it really seems like it only took a few ounces for an entire gas tank...the bottles I find now in 32 oz say add 1 oz per gallon, so it takes almost the entire bottle for my fuel tank, and I just don't recall that, I could be wrong though. It is slightly possible I am thinking about another product, like Lucas that was more concentrated, but I haven't used anything but techron in several years. So I'd just like to confirm if such a product existed/if it still exists, or if I am recalling from a long time ago some other product that I tried. Am I crazy??
