Well, I didn't think there was any conspiracy going on, but do as you like.

The info is out there to help others that may not know there are differences in oils to make the right choice.

EDIT: The above tests were done on standard auto engines, which typically have less lift and valve spring pressure than motorcycle engines. As the lift and valve spring pressures increase, so does the chances of galling.

Really Jim - there are inexpensive solutions (diesel oil) that have what are generally agreed to be "safer" levels, so unless you really want to run an inexpensive auto oil to save a few cents there shouldn't be much debate.
