I poured 5 ounces of MMO into my tank last night with 12 gallons of gasoline. The bottle says to add 4 ounces to 10 gallons, so I figured I was pretty close to the recommended ratio. It'* supposed to keep your fuel system clean AND lubricate the valve stems. Anyway, I put in a relatively small amount of it, so I'm not to worried about ill effects. Any of you guys try this stuff in your tank?

Well so far there hasn't been any changes in performance that I can tell; that'* probably a good thing concidering that it ran fine before I started this experiment.
