Am owner of 2 cycle 583cc MXZ with 3200 miles. Is there an additive that should be added to gas or an oil that has "decarb" agents mixed with the oil to prevent carbon buildup and oil "coaking" of the rings? I use TCW 3 rated for my 150HP bassboat motor with "carb X" mixed with the oil. I assume that the technology is the same? Thanks for any clarification.
