Call me a believer. MMO worked to loosen up stuck valves in a 36 Ford LB engine parked for thirty years. I add 5 ounces at every oil change to my high-mileage 2008 GMC Sierra pick-up and there is a very noticeable difference in valve train noise. I add a couple of capfuls to every small lawn and garden equipment engine, both 2 and 4 cycle. Snowmobiles and Honda minibikes, too. No carb issues, whatsoever.
