The affidavit on page 26 of the study says "the test results reported in the document entitled 'A Study of Motorcycle Specific Oils' prepared for the AMSOIL Power Sports Group in March of 2006 are correct."
To me, that indicates AMSOIL contracted for and paid a company to conduct the study. That leaves me and everyone else who read that document to draw our own conclusions about it. I didn't need to read this study, as it is an ex post facto insignificance to my decision to use their products. My point is, in the end, AMSOIL is tooting their own horn. See for yourself @ http://www.amsoil.com/lit/g2156.pdf
I read all that too, Henry, and a few months ago as well. Plus had an aquaintance who was an engineer for Mobil I and provided me a history of the development of the VTWIN they offer...of course, he tooted the Mobil I product, and it was developed specifically for HD engines...but, he was also an honest man, and said Amsoil was also an excellent product and woud not hesitate in using it either. So, even if Amsoil is tooting their horn, I don't think they are misleading anyone.
