I've read that 0116 can be used at a "reasonable" concentration greater than the recommended amount of 1oz. per gallon of gas. That's vague. What is the max oz./gal. that will not be harmful, and what is the minimum oz./gal. that will actually be effective.

The maximum safe concentration of Berryman B-12 Chemtool Fuel System Cleaner (part #0116) will vary greatly depending on the application. For instance, an older boat or lawn mower with rubber fuel lines might not hold up to more than 2 oz/gal of 0116 while a new boat or mower with modern fuel lines might be fine with 4 or even 8 oz/gal. That said, please note that the maximum permissible concentration for on-road use per EPA regulations is 1 oz/gal of gasoline.
The minimum concentration of 0116 that will be effective also depends considerably on the application. For instance, cleaning dirty intake valves is a much more demanding task than cleaning dirty fuel injectors or carburetors. The minimum effective concentration also depends on how severe the deposits are.
