OMC,
Do you recall the origin of this info? I seem to remember the same. In 2007, the Turbo Diesel Register performed an excellent study on both dino and syn oils (Issue 56 and 57). Unfortunately, since the study was specific to the Cummins, it's impossible to draw any conclusions about shear properties. Redline was one of the top performing oils in that test. However, at a whopping $35/gal., the thinking was that there were other good oils that were more economical.
Sorry...didn't mean to hijack.
