That’s the stuff. You said it with some incredulity, like perhaps you can’t believe I would recommend this garbage. I mean, just the caps and double question mark. Not trying to give you grief, just not sure what your POV is here. I’ve read good reviews for the stuff. Lately I’ve been reading that you don’t want to use too much. I saved a couple of those Lucas fuel additive bottles, the tall skinny ones, to use as a sort of a measuring device and convenient thing to keep in the trunk. I fill them in my shop. Instructions call for one fluid ounce for 5 gallons, those Lucas bottles hold 5 ounces. My SDL holds 23 and some gallons, I often put the whole thing in on a fill up. I could estimate four ounces, might be better. The stuff costs about eight cents an ounce, not too much to add to the price per gallon.
