I don't know that the term 'idiot' was entirely deserved...

Either way, I broke my OMP lines on my '86 about 5 years ago. This resulted in me running premix for 5 years. I pulled my tank down a few months back and had no oil residue in it at all (I did have some water though). I do run the OMP now (got new lines) due to my desire to do DOD (Displacement On Demand) at a later date.

Bear in mind that all the bumps on the road and the fuel pump mix the oil and gas in the tank very well. The fuel in the line is moving too quickly to settle out. Besides that- it takes several years for two-cycle oil to settle out of gas in a can.

As to the no injection on decel. The OMP does not inject very much on decel either (the injection quantity is throttle-related - at least on an S4).
