Evinrude Carbon Guard:

Anybody knows if Evinrude Carbon Guard would help an older outboard motor. (Evinrude 1992). Evinrude says “Per OMC BRP Bombardier (Evinrude - Johnson) recommendations: Add Carbon Guard to the fuel tank each time you add gasoline.
For 2 cycle and direct injection engines add 1 ounce of carb guard for every 8 gallons of gasoline” For 4 Stroke engines add 1 ounce of Carbon Guard for every 16 gallons of gasoline. Can I just insert some in each cylinder via the spark plug holes and then turn the engine over? Also if it goes in the fuel tank can I add 2-3 ounces for ever 8 gallons instead of the recommend ion of I once Thank you.
 
"Carbon guard is for fuel and

"Carbon guard is for fuel and fuel ONLY! Do not exceed the recommendations.
If You want something in the cylinders to get rid of carbon build-up use Engine Tuner (BRP) or Sea Foam, but follow the instructions on the can."
