If Supertech has moly why is it not considered a good oil by a lot of people?
For the same reason that some people find Amsoil or Mobil 1 or Red Line or Pennzoil or Shell or Havoline or any other oil "not good." It's human nature.quote:

Not sure. In the past they found some sealants were hurting the Oxygen Sensors,,these were the Silicaamorphous and Acetoxysilane types. I think many are using the Dimethylsiloxane type sealants today that still appear as though they are regular old RTV. It would be very difficult I would think to find out exactly what type a manufacturer was using.quote:
