According to the DINAN techs at Prestige BMW in Ramsey NJ, yes. To my untrained eye the contents of my OCC was just fuel vapor but apparently I was wrong. They told me they checked an N55 last month with the OCC on it and the build up was significantly less than stock, in some areas bone dry.
It is not a DINAN product, so I would think they would have no vested interest in promoting the worthiness of the OCC unless they saw the results and believed in its effectiveness. As a result, I bought it again, and I am currently awaiting its arrival from Terry.
I am of course going by a DINAN tech, so I would think I should trust his judgement
Yea I spoke too soon on the rattle- the search continues
